Students test the GaitMate harness and structure as a tool to help recovering patients walk.
Penn students have been building their knowledge and hands-on experience in places all over the world through Penn Global Seminars. Last May, “Robotics and Rehabilitation” brought Penn students back to the tropical island of Jamaica to collaborate with local university students and make an impact on recovery and quality of life for patients in Kingston and beyond.
Course leaders Camillo Jose (CJ) Taylor, Raymond S. Markowitz President’s Distinguished Professor in Computer and Information Science (CIS), and Michelle J. Johnson, Associate Professor of Physical Medicine and Rehabilitation at the Perelman School of Medicine and Associate Professor in Bioengineering (BE) and Mechanical Engineering and Applied Mechanics (MEAM) at Penn Engineering, brought the first cohort of students to the island in 2019.
“CJ and I are both Jamaicans by birth,” says Johnson. “We were both excited to introduce the next generation of engineers to robotics, rehabilitation and the process of culturally sensitive design in a location that we are personally connected to.”
As they built relationships with colleagues at the University of West Indies, Mona (UWI, Mona) and the University of Technology, Jamaica (UTECH), both Johnson and Taylor worked to tie the goals of the course to the location.
“In the initial iteration of the course, our goal was to focus on the applications of robotics to rehabilitation in a developing country where it is necessary to create solutions that are cost effective and will work in under-resourced settings,” says Taylor.
Taylor and Johnson wanted to make the course a regular offering, however, due to COVID-related travel restrictions, it wasn’t until last spring that they were able to bring it back. But when they did, they made up for lost time and expanded the scope of the course to include solving health problems for both people and the environment.
“While we started with a focus on people, we realized that the health and quality of life of a community is also impacted by the health of the environment,” says Taylor. “Jamaica has rich terrestrial and marine ecosystems, but those resources need to be monitored and regulated. We ventured into developing robotics tools to make environmental monitoring more effective and cost-friendly.”
One of those student-invented tools was a climate survey drone called “BioScout.”
“Our aim was to create a drone to monitor the ecosystem and wildlife in Jamaica,” says Rohan Mehta, junior in Systems Science and Engineering. “We wanted to help researchers and rangers who need to monitor wildlife and inspect forest sectors without entering and disturbing territories, but there were no available drones that met all of the following criteria necessary for the specific environment: affordable, modular, water-resistant and easy to repair. So we made our own.”
Another team of students created a smart buoy to reduce overfishing. The buoy was equipped with an alarm that goes off when fishermen get too close to a no-fishing zone.
Five other student teams dove into projects aligned to the original goals of the course. Their devices addressed patients’ decreased mobility due to diabetes, strokes and car accidents. These projects were sponsored by the Sir John Golding Rehabilitation Center.
One of which, the GaitMate, was engineered to help stroke patients who had lost partial muscle control regain their ability to walk.
“We developed a device that supports a patient’s weight and provides sensory feedback to help correct their form and gait as they walk on a treadmill, ultimately enhancing the recovery process and providing some autonomy to the patient,” says Taehwan Kim, senior in BE. “The device is also relatively cheap and simple, making it an option for a wide variety of physical therapy needs in Jamaica and other countries.”
Each year, the the Department of Bioengineering seeks exceptional candidates to conduct summer research in bioengineering with the support of two scholarships: the Abraham Noordergraaf Student Summer Bioengineering Research Fund and the Blair Undergraduate Research Fund in the Department of Bioengineering. These scholarships provide a living stipend for students to conduct research on campus in a Penn research lab under the mentorship of a faculty member. The Abraham Noordergraaf Student Summer Bioengineering Research Fund provides financial support for undergraduate or graduate summer research opportunities in bioengineering with a preference for study in the area of cardiovascular systems. Dr. Noordergraaf, who died in 2014, was a founding member and first chair of Penn Bioengineering. The Blair Undergraduate Research Fund in the Department of Bioengineering supports three to five undergraduate research scholars each year with the support of Dr. James C. Blair II. After a competitive round of proposals, the following six scholars were chosen for the Summer 2022 semester. Keep reading below for the research abstracts and bios of the awardees.

“Lipid nanoparticle-mediated delivery of RAS protease to inhibit cancer cell growth”
Mutations in RAS, a family of proteins found in all human cells, drive a third of cancers, including many pancreatic, colorectal, and lung cancers. However, there are still no therapies that can effectively prevent RAS from causing tumor growth. Recently, a protease was engineered to specifically degrade active RAS, offering a promising new tool for treating these cancers. However, many protein-based therapies still cannot be effectively delivered to patients. Lipid nanoparticles (LNPs), which were used in the Pfizer-BioNTech and Moderna COVID-19 vaccines, have emerged as a promising platform for safe and effective delivery of both nucleic acids and proteins. We formulated a library of LNPs using different cationic lipids. We characterized the LNPs by size, charge, and pKa, and tested their ability to deliver fluorescently labeled protease. The LNPs were able to encapsulate and deliver a RAS protease, successfully reducing proliferation of colon cancer cells.
Ella is a senior from Maryland studying bioengineering and chemistry. She works in Dr. Michael Mitchell’s lab, developing lipid nanoparticles to deliver proteins that reduce cancer cell proliferation. She has also conducted research on early-stage cancer detection and therapy monitoring (at Stanford University) and drug delivery across the blood-brain barrier for neurodegenerative diseases (at University of Maryland). She is passionate about translational research, science communication, and promoting diversity in STEM.

“Investigating Viability in ATR and WEE1 Inhibitor Treated Ovarian Cancer Cells”
High-grade serous ovarian cancers (HGSOCs) are an aggressive subtype of ovarian cancer, accounting for up to 80% of all ovarian cancer-related deaths. More than half of HGSOCs are homologous recombination deficient; thus, they lack a favorable response when treated with common chemotherapeutic trials. Therefore, new treatment strategies must be developed to increase the life expectancy and quality of life of HGSOC patients. To address the lack of effective treatment options, the Brown Lab is interested in combining ATR and WEE1 inhibition (ATRi/WEE1i) to target HGSOC cells. It has previously been shown that low-dose ATRi/WEE1i is an effective treatment strategy for CCNE1-amplified ovarian cancer-derived PDX tumors (Xu et al., 2021, Cell Reports Medicine). Therefore, the next step is to characterize the HGSOC-specific response to ATRi/WEE1i treatment. This project aims to characterize the viability phenotype of ovarian cancer (OVCAR3) cells in the presence of ATRi/WEE1i in both single and combination treatments. With further research, Eleh hopes to prove the hypothesis low-dose combination ATRi/WEE1i treatment will result in the synergistic loss of viability in OVCAR3 cells. This goal will be achieved through the treatment of OVCAR3 cells with ranging doses of ATRi and Wee1i over 24 and 48 hour time intervals. We hope that this data will help set a treatment baseline that can be used for all OVCAR30-based viability experiments in the future.
Chiadika Eleh is a Bioengineering and Computer Science junior and a member of Penn Engineering’s Rachleff Scholar program. As a Blair Scholar, she worked in Dr. Eric Brown’s cancer biology lab, where she studied cell cycle checkpoint inhibitors as a form of cancer treatment.
“Tbc1d2b regulates vascular formation during development and tissue repair after ischemia”
The mechanisms behind endothelial cells forming blood vessels remains unknown. We have identified Tbc1d2b as a protein that is integral to the regulation of vascular formation. In order to investigate the role of Tbc1d2b in tubule formation, fibrin gel bead assays will be conducted to evaluate how the presence of Tbc1d2b is required for angiogenesis. Fibrin gel bead assays simulate the extracellular matrix environment to support the in vitro development of vessels from human umbilical vein endothelial cells (HUVEC) coated on cytodex beads. In order to confirm the success of angiogenesis, immunostaining for Phalloidin and CD31 will be conducted. After confirmation that fibrin gel bead assays can produce in vitro tubules, sgRNA CRISPR knockout of Tbc1d2b will be performed on HUVEC cells which will then be used to conduct more fibrin gel bead assays. We hypothesize that HUVEC with the Tbc1d2b knockout phenotype will be unable to form tubules while wild type HUVEC will be able to.
Gloria Lee is a rising senior studying Bioengineering and Physics in the VIPER program from Denver, Colorado. Her research in Dr. Yi Fan’s lab focuses on the role that proteins play in cardiovascular tubule formation.

“Development and Integration of Dynamically Modulating Control Systems in the Rehabilitation Using Community-Based Affordable Robotic Exercise System (Rehab CARES)”
As the number of stroke patients requiring rehabilitative care continues to increase, strain is being put onto the US health infrastructure which already has a shortage of rehabilitation practitioners. To help alleviate this pressure, a cost-effective robotic rehabilitative platform was developed to increase access to rehabilitative care. The haptic TheraDrive, a one-degree of freedom actuated hand crank that can apply assistive and resistive forces, was modified to train pronation and supination at the elbow and pinching of the fingers in addition to flexion and extension of the elbow and shoulder. Two controllers were created including an open-loop force controller and a closed-loop proportional-integral (PI) with adaptive control gains based on subject performance in therapy-game tasks as well as galvanic skin response. Stroke subjects (n=11) with a range of cognitive and motor impairment completed 4 therapy games in both adaptive and non-adaptive versions of the controllers (n=8) while measuring force applied on the TheraDrive handle. Resulting normalized average power versus Upper Extremity Fugl-Meyer (UE-FM) and Montreal Cognitive Assessment (MoCA) correlation analyses showed that power was strongly correlated with UE-FM in 2 of the conditions and moderately correlated with the other 6 while MoCA was moderate correlated to 2 of the conditions and weakly correlated to the rest. Mann-Whitney U-tests between adaptive and non-adaptive versions of each therapy game showed no significant differences with regards to power between controller types (p<0.05).
Gary is a master’s student in the School of Engineering studying Mechanical Engineering and Applied Mechanics with a concentration in Robotic and Mechatronic systems. His research primarily focuses on developing affordable rehabilitation robotics for use in assessment and game-based therapies post neural injury. Many of his interests revolve around the design of mechatronic systems and the algorithms used to control them for use in healthcare spaces.

“Optogenetic Control of Developing Kidney Cells for Future Treatment of End-Stage Renal Disease”
This project sought to build from prior research in the Hughes Lab on the geometric and mechanical consequences of kidney form on cell and tissue-scale function. While the developmental trajectory of the kidney is well understood, little is currently known about many factors affecting nephron progenitor differentiation rate. Insufficient differentiation of nephron progenitor cells during kidney formation can result in lower nephron number and glomerular density, which is a risk factor for progression to end-stage renal disease later in life. Prior studies indicated that the amount of nephron differentiation – and thus function of the adult kidney – is correlated to the packing of ureteric tubule tips present at the surface of the kidney. Building off of research conducted in the Bugaj Lab, we found that inserting an optogenetic construct into the genome of human embryonic kidney (HEK) cells allowed us to manipulate the contraction of those cells through exposing them to blue light. Manipulating the contraction of the cells allows for the manipulation of the packing of ureteric tubule tips at the kidney surface. We used a lentiviral vector to transduce HEK293 cells with the optogenetic construct and witnessed visible contraction of the cells when they were exposed to blue light. Future work will include using CRISPR-Cas9 to introduce the optogenetic construct into IPS cells.
Priya is a junior studying bioengineering and had the opportunity to work on manipulating developing kidney cells using an optogenetic construct in the Hughes Lab this summer. She is thrilled to continue this research throughout the coming school year. Outside of the lab, Priya is involved with the PENNaach dance team and the Society of Women Engineers, as well as other mentorship roles.

“Expression and Characterization of an Anti-Aβ42 scFv”
Background: Amyloid Beta (Aβ42) fibrils contribute to the pathology of Alzheimer’s Disease. Numerous monoclonal antibodies have been developed against Aβ42. In this study we have designed and expressed a short chain variable fragment specific to Aβ42 (Anti-Aβ42 scFv). To characterize our anti-Aβ42 scFv we have performed structural analysis using transmission electron microscopy (TEM) and binding kinetics using microscale thermophoresis (MST) compared to commercially available antibodies 6E10, Aducanumab, and an IgG isotype control. The goal of this study is to determine if labeling densities and binding constants for Aducanumab and anti-Aβ42 scFv are not significantly different.
Method: To characterize Aβ42 fibril associated antibodies we used negative stain TEM. Aβ42 fibrils were stained on a glow discharged copper grid, and incubated with gold conjugated anti-Aβ42 scFv, 6E10—which binds all Aβ species, aducanumab, or IgG isotype control. Labeling densities were calculated as the number of fibril-associated gold particles per 1 μm2 for each image. Next, we used microscale thermophoresis determine the binding kinetics. Antibodies or anti-Aβ42 scFv were labeled with Alexa Fluor-647 and unlabeled Aβ42 was titrated in a serial dilution over 16 capillaries. The average fluorescence intensity was plotted against the antibody or scFv concentration and the curves were analyzed using the GraphPad Prism software to calculate the dissociation constant (KD) values.
Results: We found a significant difference, tested with a one-way ANOVA (P <0.0001), in gold particle associated Aβ fibrils per 1 μm2 between anti-Aβ42 scFv, 6E10, aducanumab, and IgG isotype control. Further analysis of aducanumab and 6CO3 with unpaired student t-test indicates significant differences in fibril associated gold particles between aducanumab vs. 6E10 (P=0.0003), Aducanumab vs. Isotype control (P <0.0001), anti-Aβ42 scFv vs 6E10 (p=0.0072), and anti-Aβ42 scFv vs Isotype Control (P=0.0029) with no significant difference in labeling densities between Aducanumab and anti-Aβ42 scFv. The expected KD values from MST were 1.8μM for Aducanumab and anti-Aβ42 scFv, 10.3nM for 6E10 and no expected binding for the isotype control. The experimental KD values for anti-Aβ42 scFv and 6E10 are 0.1132μM and 1.467μM respectively. The KD value for Isotype control was undetermined, as expected, however, the KD for Aducanumab was undetermined due to suboptimal assay conditions. Due to confounding variables in the experimental set up such as the use of Aβ1-16 compared to Aβ42 and the use of different fluorophores—5-TAMRA, Alexa Fluor 647 or FITC— the experimental KD values were off by several orders of magnitude.
Conclusion: We have illustrated similar labeling densities between Aducanumab and our anti-Aβ42 scFv. In the future, we will further optimize the MST assay conditions and compare the KD values obtained by MST with other techniques such as surface plasma resonance.

Devin Carroll, a doctoral candidate in the School of Engineering and Applied Sciences, is designing a modular robot called StickBot, which may be adapted for rehabilitation use in global public health settings.
StickBot in walking mode, using the sticks as legs to propel itself across the table.
In late summer, just as the leaves were starting to crisp and curl in the heat, Devin Carroll walked out of his apartment, looked on the ground, and picked up a couple of sticks that he thought might work for his robot. About half an inch thick and the length of an adult hand, he stripped the three sticks of their bark and lashed them with string to StickBot, a modular robot composed of circuitry, actuators, a microcontroller, and a motor driver.
Controlling the robot using an app he designed, Carroll shows how StickBot can pivot from using the sticks as legs in “crawler mode,” to using them as arms. In “grasper mode,” the sticks are attached to a controller plate on one side to form a hinge joint while moving with their free end to hold a cup upright.
Rather than a static, singular invention, StickBot is an idea, a flexible system that can be reconfigured in a variety of ways. A modular robot, StickBot’s components can be added, adjusted, and discarded as needed.

Every spring, the Graduate Association of Bioengineers (GABE) at Penn partners up with iPraxis, an educational non-profit organization based in Philadelphia, to organize BETA Day, an event that brings together Bioengineering graduate students and local Philadelphia grade school students to introduce them to the field of bioengineering, the life of graduate students, and hands-on scientific demonstrations. Due to COVID-19 restrictions, we adapted the traditional in-person BETA Day into a virtual event on Zoom. This year, we assembled kits containing the necessary materials for our chosen demonstrations and worked with iPraxis to coordinate their delivery to partner schools and their students. This enabled students to perform their demonstrations in a hands-on manner from their own homes; over 40 students were able to participate in extracting their own DNA and making biomaterials with safe household materials.
Michelle Johnson presents on her work in robotics
The day began with a fantastic lecture by Michelle Johnson, Associate Professor in Bioengineering and Physical Medicine and Rehabilitation, who introduced students to the field of rehabilitation robotics and shared her experience as a scientist. Students then learned about DNA and biomaterials through lectures mediated by the graduate students Dayo Adetu and Puneeth Guruprasad. After each lecture, students broke into breakout rooms with graduate student facilitators where they were able to get some hands-on scientific experience as they extracted DNA from their cheek cells and fabricated alginate hydrogels. Michael Sobrepera, a graduate student in Dr. Johnson’s lab, concluded the event by giving a lecture on the process of robotics development and discussed where the field is heading and some important considerations for the field.

While yet another online event may seem unexciting, throughout the lectures students remained exceptionally engaged and raised fantastic questions ranging from the accessibility of low income communities to novel robotic therapeutic technologies to the bioethical questions robotic engineers will face as technologies advance. The impact of BETA day was evident as the high school students began to discuss the possible majors they would like to pursue for their bachelor’s degrees. Events like BETA Day give a glimpse into possible STEM fields and careers students can pursue.
Brit Shields, Senior Lecturer in Bioengineering, has brought her expertise in the history and sociology of science to her leading role in developing and improving the ethics curriculum for all students in the School of Engineering and Applied Science. Most recently, this includes adapting the core ethics engineering ethics course “Technological Innovation and Civil Discourse in a Dynamic World” (EAS 204) for the Stavros Niarchos Foundation (SNF) Paideia Program. SNF Paideia courses, open to all Penn undergraduates, “integrate students’ personal, professional, and civic development […] focus[ing] on dialogue, wellness, service, and citizenship from different disciplinary and interdisciplinary perspectives.” A recent SNF Paideia blog post goes into detail about the changes made by Shields and co-instructor Christopher Yoo, John H. Chestnut Professor of Law, Communication, and Computer and Information Science, to suit the SNF Paideia Program, including its “explicit focus on civil discourse and technology.” According to Shields:
“I really wanted to break down the false dichotomy between technological expertise or humanities training for the students and open up the opportunity for Engineering students to consider themselves to have an important role, not just creating technological systems but also being important participants in civil discourse.”
Michelle Johnson, Ph.D.
The course also includes guest lectures by Penn faculty, including Michelle Johnson, Associate Professor in Bioengineering and Physical Medicine and Rehabilitation, and students learn to analyze how guest lecturers communicate their research to the public, for example, in the case of Johnson, in the form of a TED Talk and scholarly articles: “Through her TedTalk, journal articles and visit to the class, Michelle Johnson demonstrates how researchers are attuned to the specific preferences of the rehabilitative robots they are creating for patients…engaged scholarship at its finest.”

Yasmina Al Ghadban, a senior in the School of Engineering and Applied Science from Beirut, was able to connect her undergraduate education in bioengineering and psychology with her passion for public health through teaching, research, and extracurricular activities. Now, she is poised to leverage her “interdisciplinary lens” towards a future career in public health.
While reflecting on her undergraduate journey at Penn, senior Yasmina Al Ghadban says that she has a “ton of memories” she will take with her: lifelong friends made and skills developed through coursework, research, and teaching experiences, the chance to engage with public health communities on campus, and traveling for courses and internships. “That’s the beauty of Penn,” she says. “There’s just so many opportunities everywhere.”
As a double major in bioengineering and psychology, Al Ghadban, who is from Beirut, has certainly taken advantage of many such opportunities. Now, she is poised to leverage her “interdisciplinary lens” towards a future career in public health.
Problem-solving perspectives
Looking for a place to grow and become more independent, Al Ghadban decided to come to Penn after graduating from the International College in Lebanon. After taking an introduction to bioengineering course during her freshman year, she became enthralled by the hands-on nature of the program and enrolled in the School of Engineering and Applied Science. “I really enjoyed working with circuits and Arduino, being able to synthesize things, and I felt like being in engineering was the place where I was going to gain the most skills,” she says.
Al Ghadban is applying those skills as she completes her senior design project. She and a team of four seniors are building an autonomous robot equipped with Lidar sensors that it uses to create a map of a physical space. The team also programmed their robot to recognize high-touch surfaces that it then disinfects with UV light. “It’s a technology that is completely autonomous, cheaper than what’s on the market, and doesn’t put people at risk when they go in to disinfect,” she says. The team recently put the finishing touches on the project and presented their robot as part of a demonstration on April 14.
In addition to her degree in engineering, Al Ghadban’s interests in public and mental health spurred her to take courses and eventually pursue a double major in psychology, a field that she sees as complementary to engineering. “In psychology, we focus a lot on research and study design, research bias, and these things are similar in engineering and psychology,” she says. “Overall, I think they gave me different perspectives in terms of problem solving, and it’s nice to have that interdisciplinary lens.”
One place where Al Ghadban was able to use this interdisciplinary lens was while working as an research assistant in the Rehabilitation Robotics Lab with Michelle Johnson during her sophomore year. “The focus of the lab is to create robots for post-stroke rehabilitation, and the robotics part is very engineering-focused, but there is another part where people struggle doing the exercises,” she says. “Being able to engage with people and increasing their likelihood of doing that intervention, you rely on a lot from psychology, like interventions from positive psychology or research on how people stay engaged.”
The process of discovery sometimes starts with a hunch. Maria Ovando arrived at Penn Engineering with an affinity for math and science, extensive experience volunteering at her local health clinic and an assumption that she was preparing for a career in medicine. She was drawn to Penn Engineering because of the flexibility in the curriculum and the ability to both tailor her course of study and pursue cross-disciplinary subjects.
As a pre-med student, bioengineering seemed to be the natural choice for a major, but during her freshman year, Ovando found that she genuinely enjoyed bioengineering as a discipline in its own right, and only then did her future goals come into view.
“I’ve discovered that I have a passion for research, working on low-cost devices that can have a direct impact on individuals,” she says.
One of the most important opportunities she’s had at Penn is her work with Dr. Michelle J. Johnson at the Rehabilitation Robotics Lab in the Perelman School of Medicine. There, Ovando has been working to improve aspects of the Community-based Affordable Robot Exercise System, which helps stroke patients with lower extremity impairment. She’s also worked on a project that involved analyzing and reevaluating data in the early detection of cerebral palsy in infants. As an undergraduate, she found it both meaningful and moving to have a role in this groundbreaking research.
Since the country began shutting down in March, I have joined the majority of the world in calling the times “unprecedented”: The word, which I rarely used before the pandemic, is now a staple of my lockdown lexicon. In March, we all got the email that changed the trajectory of the rest of our semester and the school year. Since then, COVID-19 has been impacting lives here at Penn, around the nation, and the world. Hanging out with friends and family on Zoom, managing work and school from home, social distancing, wearing masks everywhere, and constantly washing hands have been the reality of our new normal for months.
It has been almost ten months since the World Health Organization declared COVID-19 a pandemic and this has posed a global crisis like nothing most of us have experienced in our lifetime. At Penn, the campus community including students and staff have rallied to keep each other safe, all while doing what is possible to ensure that lectures, teaching, and research are possible in ways that uphold the university’s mission of “strengthening the quality of education and producing innovative research and models of healthcare delivery by fostering a vibrant inclusive environment and fully embracing diversity.”
BE students Alexa Rybicki, Ifeoluwa Popoola, and Caitlin Frazee meet for BE 309 in the Gather.Town virtual lab space.
In Penn Engineering’s Bioengineering Department, the Stephenson Foundation Educational Laboratory & Bio-MakerSpace has been at the heart of ensuring that lab-based classes run as smoothly as possible given the circumstances. First off, during the summer, the lab launched a Slack site that not only kept students engaged and connected through fun, daily “Questions of the Day” but also gave them the opportunity to reach out to our staff and obtain their expertise for coursework and personal projects. The staff at the Stephenson Lab also supported and continue to support Senior Design students (BE 495) with their projects by ordering, receiving, packaging, arranging pickups, or mailing supplies needed to complete their Senior Design projects. In addition, class time takes place using Gather.Town to recreate our Bio-MakerSpace virtually. In other classes, video tutorials of some of the experiments students were missing out on were produced over the summer and made available to students so they could learn by seeing what the lab staff were doing in the videos. For the Bioengineering Modeling, Analysis, and Design (BE MAD) class (BE 309), in addition to videos, our lab Engineer, Michael Patterson, developed software through which students can enter design criteria and have experimental data emailed to them.
Picking up lab supplies outside in the Engineering complex
The staff at the lab also supported a Rehabilitation Engineering course (BE 514) taught by Michelle Johnson, Associate Professor in Physical Medicine and Rehabilitation and Bioengineering, by putting together supplies that enabled students in the class to reengineer toy bunny rabbits to be more accessible to children with disabilities. Optical Microscopy (BE 518), another Bioengineering course, taught by Christopher Fang-Yen, Associate Professor in Bioengineering and Neuroscience, offers students an introduction to the fundamental concepts of optics and microscopy. The staff at the lab put together kits and made them available for pickup by the students in the class.
In a time when the shape of education looks vastly different from what we anticipated this year, the Bio-MakerSpace has been instrumental in ensuring that students still have access to resources that make their learning experience an enriching one. In these unprecedented times, the lab has been able to encourage students to keep up and be engaged with their coursework while also fostering creativity in students, virtually and remotely. While we may not know what life after the pandemic will look like, one thing to be sure of is that the Stephenson Lab will always be a reliable place for Penn students to get support for personal projects and coursework when needed.
