The School of Engineering and Applied Science has granted tenure to six faculty members, including three from the Department of Bioengineering.

Tenured faculty at Penn Engineering demonstrate teaching excellence and international leadership in their fields of study and research collaborations.

Brian Chow
Associate Professor in Bioengineering
Chow’s research focuses on the discovery and engineering of photoreceptors and sensory proteins for manipulating and monitoring the physiology of genetically targeted cells, and the application of these tools to reveal principles of cellular dynamics. His work has advanced the rational design of light activated proteins and the use of optogenetic reagents to study cell signaling.

David Issadore
Associate Professor in Bioengineering
Issadore’s research combines microelectronics, microfluidics, and nanomaterials to create miniaturized platforms for the diagnosis of disease. His work has the potential to radically change the way we diagnose and treat diseases by bringing the technologies out of the lab and directly to the point of care.

Dongeun (Dan) Huh
Associate Professor in Bioengineering
Huh’s research aims to develop innovative bioengineering tools and technologies using biologically inspired design principles and micro- and nano-scale engineering techniques to create systems that mimic the structure and function of human physiological systems.

Linh Thi Xuan Phan
Associate Professor in Computer and Information Science
Phan’s work focuses on making cyber-physical systems (CPS) safer, faster, and more secure, both by strengthening the theoretical foundations and by developing practical solutions. Her recent projects include a cloud platform with real-time capabilities, a new diagnosis technique for timing-related faults, and new ways to defend CPS against attacks from insiders and/or external attackers.

Amish Patel
Associate Professor in Chemical and Biomolecular Engineering
Patel’s research strives to achieve a molecular-level understanding of solvation and transport in aqueous and polymeric systems, with applications ranging from the prediction of protein interactions to the design of advanced materials for water purification and energy storage. His group combines principles of statistical mechanics and liquid state theory with state-of-the-art molecular modeling and atomistic simulation techniques to study these biological, nanoscopic and polymeric systems.

Aleksandra Vojvodic
Associate Professor in Chemical and Biomolecular Engineering
Vojvodic’s research focuses on theory and computation-driven materials design. Her lab uses computational frameworks to obtain fundamental understanding of surface and interface properties of complex materials that can be used to develop theoretical models for chemical transformations and energy conversion. These models have been used to predict new catalyst materials for several chemical reactions which have been experimentally synthesized and tested, validating the desired properties of the computationally predicted catalyst material.

Brian Chow, Dan Huh, and David Issadore Promoted to Tenured Positions as Associate Professors in Penn Bioengineering

by Sophie Burkholder

We would like to congratulate Penn Bioengineering faculty members Brian Chow, Ph.D., Dongeun (Dan) Huh, Ph.D., and David Issadore, Ph.D., on all of their recent promotions to tenured positions as Associate Professors. Both Chow and Issadore taught the second half of the foundational course in the Penn Bioengineering undergraduate curriculum, Bioengineering Modeling, Analysis, and Design Laboratory, in which students form lab groups to complete modules in microfluidics, synthetic biology, bioelectrical signal analysis, and bioanalytical spectroscopy.

Outside of the classroom, Chow’s research focuses on the creation of dynamic input and output interfaces for cells through the use of optogenetics, synthetic biology, genomics, and device engineering. The Chow lab’s current projects include the exploration of functional diversity of photoreception, engineering optically active genetically encoded tools, and their applications in neuroscience and mammalian synthetic biology. His research is supported by the NIH and he is the recipient of a 2017 NSF CAREER Award. Chow also supports undergraduate innovations in research by hosting the annual Penn team for the International Genetically Engineered Machine (iGEM) competition, a program which he helped to create during his time as a graduate student at MIT. One group of Bioengineering students under Chow’s mentorship used the iGEM project as a springboard to create an accessible, open-source plate reader.

The Issadore lab at Penn focuses on the use of microelectronics and microfluidics for medical diagnostics. In projects that combine elements of bioengineering, electrical engineering, chemical engineering, and applied physics, Issadore and his team use an interdisciplinary approach to create miniaturized low-cost platforms for disease diagnosis. His company Chip Diagnostics received the JPOD @ Philadelphia QuickFire Challenge Award last month. Earlier this year, Issadore taught the Penn Engineering course Appropriate Point of Care Diagnostics (APOC), which culminated in a service trip to Ghana (read blog posts written by participating students here). This fall, he will take over the core Bioengineering undergraduate course in Bioengineering Signals and Systems, which focuses on applications in ECG signaling, cochlear implants, and biomedical imaging.

Dr. Huh is the principal investigator of the BIOLines Lab at Penn, which is best known for its work on bioinspired engineering systems that Huh calls “organs-on-a-chip.” Using design and engineering principles based on microfluidics and biomimicry, the Huh lab creates microengineered systems that can reconstitute the structural and functional complexity of healthy and diseased human physiological systems in ways not possible using traditional cell culture techniques. His research has been featured in TEDx, and he has won several prestigious honors and awards including the Bernard Langer Distinguished Lectureship, Lush Prize, the McPherson Distinguished Lectureship, CRI Technology Impact Award, John J. Ryan Medal, Design of the Year Award and Best Product of the Year Award from London Design Museum, NIH Director’s New Innovator Award, and Analytical Chemistry Young Innovator Award. This fall, Huh will teach a graduate level course in biomicrofluidics that will cover the use of microfluidics for biomedical application.

Chip Diagnostics receives the JPOD @ Philadelphia QuickFire Challenge Award

By Erica K. Brockmeier

Chip Diagnostics is the awardee of the JPOD @ Philadelphia QuickFire Challenge sponsored by Johnson & Johnson Innovation — JLABS. The Challenge was designed to accelerate healthcare innovation and commercialization within the greater Philadelphia area.

Chip Diagnostics is a Philadelphia-based device company founded in 2016 based on research from the lab of David Issadore, Assistant Professor of Bioengineering and Electrical and Systems Engineering in the School of Engineering and Applied Science. The startup combines microelectronics, microfluidics, and nanomaterials with the aim to better diagnose cancer. The company is developing technologies and digital assays for minimally-invasive early cancer detection and screening that can be done using mobile devices.

There has been a long interest in diagnosing cancer using blood tests by looking for proteins, cells, or DNA molecules shed by tumors, but these tests have not worked well for many cancers since the molecules shed tend to be either nonspecific or very rare.

Issadore’s group aims to target different particles called exosomes: Tiny particles shed by cells that contain similar proteins and RNA as the parent cancer cell. The problem, explains Issadore, is that because of the small size of the exosomes, conventional methods such as microscopy and flow cytometry wouldn’t work. “As an engineering lab, we saw an opportunity to build devices on a nanoscale that could specifically sort the cancer exosomes versus the background exosomes of other cells,” he explains.

After Issadore was approached by the IP group at PCI Ventures in the early stages of their research, Chip Diagnostics has since made huge strides as a company. Now, as the awardee of the JPOD @ Philadelphia QuickFire Challenge, Chip Diagnostics will receive $30,000 in grant funding to further develop the first-in-class, ultra-high-definition exosomal-based cancer diagnostic. The award also includes one year of residency at Pennovation Works as well as access to educational programs and mentoring provided by Johnson & Johnson Family of Companies global network of experts.

Junior Bioengineering Students Complete Their Laboratory Course with Creatively Designed Spectrophotometers

by Sophie Burkholder

To finish the second half of Bioengineering Modeling, Analysis, and Design (BE MAD) Laboratory – the hallmark laboratory course of Penn’s Bioengineering program – instructors Dr. Brian Chow and Dr. David Issadore tasked junior undergraduate students with creating their own spectrophotometers for potential use in detecting water-borne pathogens in a design process that involved rapid prototyping techniques, the use of low-cost optoelectronics, and the incorporation of automation software and a graphical user interface for data acquisition. The final projects were assessed for both the creativity of the structural design of the device, and their abilities to measure optical properties of fluorescein, a chromophore used in clinical diagnostics, to determine each device’s accuracy, sensitivity, precision, and dynamic range.

For the final project of the year, many groups planned adventurous structural innovations to house their spectrophotometer circuits. Some of this year’s highlights included a fish tank complete with flashing lights and goldfish, a motorized arm that could successfully shoot a ball into a miniature basketball hoop with every spectrophotometer reading, a guitar with the ability to actually play music, and a working carousel. “My group decided to make a version of the Easy Bake Oven, using an LED oven light bulb, and a motor to open the door,” said junior Alina Rashid. “Of course, it didn’t actually cook anything because of the spectrophotometer inside, but maybe next time!” All of these designs involved the use of CAD-modeling to create sketches and parts that could then be laser-cut or 3D-printed into physical structures. The Department of Bioengineering also allotted each group with a budget for students to purchase any additional parts they required for their designs that were not already available in the lab.

On Demo Day for the spectrophotometer projects, instructors, lab staff, and friends came to the Stephenson Foundation Bioengineering Educational Laboratory and Bio-MakerSpace to assess final designs and celebrate the end of the semester. Given three solutions of unknown concentrations, students used their completed spectrophotometers to create standard curves using Beer-Lambert’s Law and attempt to determine the concentrations of the provided solutions. “I always love Demo Day because that’s when all separate aspects of the project – the mechanical design, the code, the circuitry – come together to make a device that actually works the way we planned and wanted it to all along,” said junior Jessica Dubuque. After nearly a month of working on the projects, each lab group went into Demo Day with designs they were proud of, and ended the semester on a high note with many new insights and lab skills under their belt for the beginning of their Senior Design projects in the fall.

Junior Bioengineering Students Filter ECG Signals for Use in Astronaut Fatigue-Monitoring Device

by Sophie Burkholder

Every undergraduate student pursuing a B.S.E. in Bioengineering participates in the Bioengineering Modeling, Analysis, and Design Laboratory I & II courses, in which students work together on a series of lab-based design challenges with an emphasis on model development and statistical analysis. Recently, junior undergraduates enrolled in this course taught by Dr. Brian Chow and Dr. David Issadore (both of whom recently received tenure) completed a project involving the use of electrocardiography (ECG) to innovate a non-invasive fatigue-monitoring device for astronauts that tend to fall asleep during long operations in space.

Using ECG lead wires and electrodes with a BioPac M-35 data collection apparatus, students collected raw data of their own heart and respiration rates, and loaded the data into MATLAB to analyze and calculate information like the heart rate itself, and portions of it like the QT-interval. “I think it was cool that we could measure signals from our own body and analyze it in a way that let us use it for a real-world application,” said junior Melanie Hillman about the project.

After taking these preliminary measurements, students used a combination of circuitry, MATLAB, and data acquisition boards to create both passive and active filters for the input signals. These filters helped separate the user’s breathing rate, which occurs at lower frequencies, from the heart rate, which occurs at higher frequencies, allowing for the data to be read and analyzed more easily. In their final design, most students used an active filter circuit chip that combined hardware with software to create bandpass filters of different frequency ranges for both input signals.

“It was nice to be able to do a lab that connected different aspects of engineering in the sense that we both electronically built circuits, and also modeled them theoretically, because normally there’s a separation between those two domains,” said junior Emily Johnson. On the final day of the project, Demo Day, groups displayed their designs ability to take one input from the ECG cables connected to a user, and filter it out into recognizable heart and respiration rates on the computer. This project, conducted in the in the Stephenson Foundation Bioengineering Educational Laboratory here at the University of Pennsylvania’s Department of Bioengineering, is just one of many examples of the way this hallmark course of the bioengineering curriculum strives to bring together all aspects of students’ foundational engineering coursework into applications with significance in the real world.

Week in BioE (February 28, 2019)

by Sophie Burkholder

Louisiana Tech Sends First All-Female Team to RockOn

A team of faculty and students from Louisiana Tech University will participate in RockOn, a NASA-sponsored workshop on rocketry and engineering. Mechanical Engineering Lecturer Krystal Corbett, Ph.D., and Assistant Professor of bioengineering Mary Caldorera-Moore, Ph.D., will work together to lead the university’s first team of three all-female students at the event. At the program, they will have the chance to work on projects involving components of spacecraft systems, increasing students’ experience in hands-on activities and real-world engineering.

Refining Autism Treatments Using Big Data

Though treatments like therapy and medication exist for patients with autism, one of the biggest challenges that those caring for these patients face is in measuring their effects over time. Many of the markers of progress are qualitative, and based on a given professional’s opinion on a case-by-case basis. But now, a team of researchers from Rensselaer Polytechnic Institute (RPI) hopes to change that with the use of big data.

Juergen Hahn, Ph. D., and his lab recently published a paper in Frontiers in Cellular Neuroscience discussing their findings in connecting metabolic changes with behavioral improvements in autistic patients. Their analysis looks for multiple chemical and medical markers simultaneously in data from three distinct clinical trials involving metabolic treatment for patients. Being able to quantitatively describe the effects of current autism treatments would revolutionize clinical trials in the field, and lead to overall better patient care.

Penn Engineers Can Detect Ultra Rare Proteins in Blood Using a Cellphone Camera

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many conditions, such as the early detection of certain cancers or the diagnosis of traumatic brain injury, where the relevant biomarkers only appear in vanishingly small quantities. Commercial approaches to ultrasensitive protein detection are starting to become available, but they are based on expensive optics and fluid handlers, which make them relatively bulky and expensive and constrain their use to laboratory settings.

Knowing that having this sort of diagnostic system available as a point-of-care device would be critical for many conditions — especially traumatic brain injury — a team of engineers led by Assistant Professor in the Department of Bioengineering, David Issadore, Ph.D., at the University of Pennsylvania have developed a test that uses off-the-shelf components and can detect single proteins with results in a matter of minutes, compared to the traditional workflow, which can take days.

Treating Cerebral Palsy with Battery-Powered Exoskeletons

Cerebral palsy is one of the most common movement disorders in the United States. The disorder affects a patient’s control over even basic movements like walking, so treatments for cerebral palsy often involve the use of assistive devices in an effort to give patients better command over their muscles. Zach Lerner, Ph.D., is an Assistant Professor of Mechanical Engineering and faculty in Northern Arizona University’s Center for Bioengineering Innovation whose research looks to improve these kinds of assistive devices through the use of battery-powered exoskeletons.

Lerner and his lab recently received three grants, one each from the National Institute of Health (NIH), the National Science Foundation (NSF), and the Arabidopsis Biological Resource Center, to continue their research in developing these exoskeletons. Their goal is to create devices with powered assistance at joints like the ankle or knee to help improve patient gait patterns in rehabilitating the neuromuscular systems associated with walking. The team hopes that their work under these new grants will help further advance treatment for children with cerebral palsy, and improve overall patient care.

People & Places

David Aguilar, a 19-year-old bioengineering student at Universitat Internacional de Catalunya made headlines recently for a robotic prosthetic arm that he built for himself using Lego pieces. Due to a rare genetic condition, Aguilar was born without a right forearm, a disability that inspired him to play with the idea of creating his own prosthetic arm from age nine. His design includes a working elbow joint and grabber that functions like a hand. In the future, Aguilar hopes to continue improving his own prosthetic designs, and to help create similar versions of affordable devices for other patients who need them.

This week, we would like to congratulate two recipients of the National Science Foundation’s Career Awards, given to junior faculty that exemplify the role of teacher-scholars in their research. The first recipient we’d like to acknowledge is the University of Arkansas’ Kyle Quinn, Ph.D., who received the award for his work in developing new image analysis methods and models using the fluorescence of two metabolic cofactors. Dr. Quinn completed his Ph.D. here at Penn in Dr. Beth Winkelstein’s lab, and received the Solomon R. Pollack Award for Excellence in Graduate Bioengineering Dissertation Research for his work.

The second recipient of the award we wish to congratulate is Reuben Kraft, Ph.D., who is an Assistant Professor in Mechanical and Biomedical Engineering at Penn State. Dr. Kraft’s research centers around developing computational models of the brain through linking neuroimaging and biomechanical assessments. Dr. Kraft also collaborates with Kacy Cullen, Ph.D., who is a secondary faculty member in Penn’s bioengineering department and a member of the BE Graduate Group faculty.

Finally, we’d like to congratulate Dawn Elliott, Ph.D., on being awarded the Orthopaedic Research Society’s Adele L. Boskey, PhD Award, awarded annually to a member of the Society with a commitment to both mentorship and innovative research. Dr. Elliott’s spent 12 years here at Penn as a member of the orthopaedic surgery and bioengineering faculty before joining the University of Delaware in 2011 to become the founding director of the bioengineering department there. Her research focuses primarily on the biomechanics of fibrous tissue in tendons and the spine.

APOC Ghana 2018: Day 4

By Xuanjie (Lucas) Gong, Biotechnology MS ’19; Shihan Dong, Biotechnology MS ’19; and Princess Aghayere, Health & Societies ‘19

Today, we all went to the Maternal and Child Health Hospital in Rural Kumasi. The main purpose of the visit was to observe malnutrition cases in children and to interact with doctors and nurses who treat children suffering from malnutrition.

While visiting the clinic, the nutrition group asked the questions that we prepared yesterday. It turns out that the situations here match up with our research. Doctors and nurses use WHO standards to determine the nutrition status of the kids. Also, they use MUAC tape to determine the severe acute malnutrition. Children who have MUAC less than 11.5 cm will be sorted into a severe acute malnutrition group.

As for solutions or treatments, they do know about and have RUTF (Ready-to-Use Therapeutic Food). We also learned that they have therapeutic milk, F-75 and F-100, to treat malnourished children in different phases. They have F-75 to use at the starting phase of treatment. If F-75 helps to stabilize the children, they move onto F-100, and they use diluted F-100 for children under 6 months.

We had 2 cases that we mainly focused on. The first case was of a 3-year-old girl who suffered from Kwashiorkor, Marasmus, and Marasmic Kwashiorkor. All 3 diseases are signs of severe acute malnutrition. She had been there for 3 weeks for treatment, and her condition was not improving. The doctors attributed her declining condition to poverty and the mother’s psychiatric problems. The patient’s mother has already lost two children to the same condition. The doctors describe the girl’s status as unstable because she often vomits and isn’t gaining weight. The second patient is a child exposed to HIV as a result of her mother being positive for the disease. Because she is only 3 months old, blood cannot be drawn, and testing cannot be done to ensure her HIV status.

In the evening, we went to a church to give a presentation to local women with little to no education. We started by asking them what they eat everyday, and luckily we received a lot of responses. From their responses, we could clearly see that their diet lacked components of vegetables and fruits. Then, we delivered a brief speech containing basic nutrition knowledge, mainly based on the six essential nutrients. We explained the function of these nutrients and some local sources to obtain them. Surprisingly, one of the female audience members said that this was her first time hearing about vitamins and minerals.

During the question and answer segment of our presentation, some women asked about the different types of sources for minerals and vitamins. In particular, one woman asked about the foods that she could eat to help with her hypertension. To our surprise, another women asked whether her intake of fruits was excessive. This question made us think about people’s awareness of obesity and other diseases related to overeating. At the end of the presentation, the audience was happy about what we presented today and looked forward to learning more on our next visit.

APOC Ghana 2018: Day 3

By Xuanjie (Lucas) Gong, Biotechnology MS ’19; Shihan Dong, Biotechnology MS ’19; and Princess Aghayere, Health & Societies ‘19

This morning, we had our official kickoff in the morning. It was a great meeting with Dr. Ellis, the Dean of School of Public Health. In the afternoon, professors from different schools delivered three lectures about the state of mental health, maternal and child nutrition, and health systems in Ghana.

Ghana 2018 The mental health lecture, given by Dr. Emma Adjaottor, was impressive and surprising. We are so lucky that we met one of the psychiatric physicians among a hundred across the country. The doctor frankly introduced mental health development in Ghana. Though they have lagged behind, they have made a lot of progress, with the number of psychiatrists in Ghana recently increasing from single digits to the double digits. Dr. Adjattor emphasized that the epidemiology of mental health in Ghana is nearly identical to the rest of the world, particularly in terms of incidence and prevalence, even though it is severely under-reported. The doctor explained that, although the epidemiology is the same, the terms used to describe these issues are often different, relying on more local ideas, such as spirits and witchcraft.

The maternal and child nutrition lecture, given by Dr. Samuel Newton, was even more astonishing. Kangaroo mother care (KMC), in which a prematurely born infant is given constant skin-to-skin contact with the mother, is undergoing study in Ghana, and it has shown promising outcomes. Even with limited studies, KMC has been found to greatly increase the likelihood of survival even when using “surrogates,” such as grandmothers and even fathers. The professor also introduced another study that found that the application of oxytocin during the third stage of labor in mothers at risk of postpartum hemorrhage (PPH) greatly decreased the likelihood of PPH.

Finally, Professor Ellis Owusu-Dabo gave an extensive lecture covering the health systems of Ghana, which are logically and hierarchically managed, with administrations at the national, local, district, sub-district, and community levels. We also learned about the insurance program in Ghana. For formally employed workers, national insurance participation is mandatory, as it is funded by a mandatory tax on their income, like in many socialist countries. However, insurance coverage is a more complicated matter in Ghana, in which a very large proportion of the population is not formally employed and instead earn its living through trading and cash-paying jobs. For these people, other than the free public health services provided by the government such as malaria, tuberculosis, and HIV care, they must pay out of pocket for many other services.

Tomorrow will be the very first clinic visit, where we can observe children suffering from severe acute malnutrition. So the three of us in the nutrition group, Princess, Shihan, and Xuanjie, gathered together after dinner to discuss what we would ask the doctors and nurses during the visit. We agreed that, at first, we should ask whether we can take pictures to record. As for nutrition, we will ask how healthcare workers there define malnutrition.

To our knowledge, malnutrition standards are normally based on BMI, which is a composition of weight, height, and age-related data. We want to know whether Ghanaian healthcare professions use the same standards here, as well as how the local standards differ from the established WHO standards. Furthermore, we will ask for access to their local data sets. In addition to the results of malnutrition, we also want to know what the major causes of malnutrition are. We assumed that the principal cause is poverty, and based on this assumption, we want to ask them whether there are any welfare systems or NGOs helping to resolve the problem. We hope to find out what the clinics’ initial steps are to resolve malnutrition. Our last question involves how macronutrients are measured.

Tomorrow evening, we will give an open presentation in a local church to female market workers. We first planned to deliver the presentation in a discussion form, but considering the language barrier and other factors, we decided to give a speech, but we will ask simple questions. We thought that the scope of our research was not appropriate for local life in Ghana because much of the research was done in the U.S.; thus, it was necessary to get the input of local people. By asking them questions about what they eat on a daily basis, we want to make our research as appropriate as possible. In relation to our presentation, we will briefly introduce what nutrition is and explain the 6 essential nutrients through definitions and explanation. For example, when introducing carbohydrates, we will refer to fufu or banku, which are local main dishes basically consisting of starch. Also, we came up with an educational idea for the future. If we have a projector, we could possibly show some dishes to let the audience choose which is more nutritious, to provide general idea of a nutritious diet.

APOC Ghana 2018: Day 2

By Sandy Tang, Bioengineering ’19; Eliza Culp, Fine Arts ’20; and Jessica Fan, Biotechnology MS ‘18

This morning, we had a chance to sleep in a bit and recover from our busy travel day. We had a delicious breakfast that consisted of porridge with sugar cubes, sausage, hard boiled eggs, a locally specialized donut made of beans, watermelon, butter bread, and a variety of hot drinks: yum. After our breakfast, a group of us went on a walk around campus, and another group went to a church service at First Love Church.

The church service started with praise worship, followed by numerous student performances. There was a dance group, a drama group, a praise group, and a traditional Twi praise group, and the congregation members were bursting with energy. The pastor then gave her sermon and afterward greeted the congregation. We made a few friends who happened to be students at the university we are staying at: KNUST.

For the other group, we explored KNUST’s expansive campus. We started to wander, and only when we noticed excessive nature did we realize we were no longer on campus. Once back on track, we saw some lizards, baby goats, and plenty of flora and returned to the residential area of campus. We accidentally entered a boy’s dorm but caught a glimpse of what it would be like to be a student at KNUST. Inside the dorm, a pastor was giving a fiery sermon, and many students were hand washing laundry in the courtyard. After leaving the dorms a few of us bought some amazing meat pies, for only 1 Cedi (about a quarter)!

Around 1 p.m., we all got into our bathing suits to head to the pool! The ride was short, and we were excited to have some relief from the heat. We ordered some food before entering the water; there was a choice of jollof or fried rice with either fish or chicken. After ordering our food, we applied sunscreen and dove into the water. There were many other people in the pool already, so we made some friends with the swimmers our age, many of whom were instructors. Shortly after being in the water, Genevieve and Estabelle, two young girls, joined us in the pool, and we played with them and carried them around in the pool. It was such a great time.

We stayed until the pool closed at 6 p.m. and then dried off and took the bus back home. A few of us bought sweet treats from the little shop in our graduate student hostel, Tek Credit. Then, dinner was brought to us by Nana Yaa: a meal of yams, spinach fish stew, rice, fried fish, beef and water melon. We had a brief Twi lesson from Nana Yaa on basic greetings. Our night ended with a quick debrief from Dr. Wattenbarger about our upcoming week.

Excited for the days that lie ahead!

APOC Ghana 2018: Day 1

By Ethan Zhao, Bioengineering ’19 and Sheldon Amoo-Mitchual, Biological Basis of Behavior ‘20

Like last year, a group of Penn Engineering undergrads enrolled in ENGR566 – Appropriate Point of Care Diagnostics, a large number of them Bioengineering majors, have gone to Ghana to get some hand-on experience. They’re blogging their experiences daily.

Today we touched down in Accra bright and early at 8 a.m. We went through immigration and baggage claim without a hitch, and we met up with Nana Ya Awua-Boateng, a PhD student at the Kwame Nkrumah University of Science and Technology (KNUST), who helped us with arrangements as a translator. We loaded up the bus with luggage (both inside and out) and set off for the 5-hour bus ride to Kumasi. Along the way, we slept (a lot), given that we touched down at the equivalent of 4 a.m. EDT. We stopped in the middle for lunch and our first taste of Ghanaian jollof rice and grilled tilapia, which were incredible.

Afterward, we finished our journey to Kumasi and arrived at KNUST, where we unpacked our belongings in the hostel. We also met Salim, a medical student, and Nana Ya’s children, Nana and Genevieve. Soon after, we all took a quick trip down to Big Chinese Restaurant (its literal name) to taste Ghana’s version of Chinese food. We then went back to campus, where we finally went to bed after a long day’s journey.
