Student Spotlight: Cosette Tomita

Cosette TomitaCosette Tomita, a master’s student in Bioengineering, spoke with Penn Engineering Graduate Admissions about her research in cellular therapy and her path to Penn Engineering.

“What were you doing before you came to Penn Engineering? 

After college I wanted to get some industry experience before going to graduate school, so I spent a year working for a pharmaceutical company in New Jersey. I learned a lot—but mostly I learned that I wanted to go back into academia. So I was looking for a more research-oriented position to boost my graduate school applications, and I found a position at Penn’s cyclotron facility. Shortly after that, I applied to the master’s program. I’m still working at the cyclotron, so I’m doing the program part time. 

How has your experience in the program been so far? 

I love the research I’m doing here. I love the collaboration we have and the fact that I’m able to work with whoever I want to. And I can only say good things about my PI, Robert Mach. He’s a very busy man, but he makes time for his people. And he recognizes when somebody has a lot on their plate and he will go to bat for that person.

What’s your research all about? 

The focus of my PI’s lab is on neurodegenerative diseases and opiate use, so we’re looking to make imaging agents and antagonists that can help with the opioid crisis. 

For my project, I wanted to look at treating neurodegenerative disease from the perspective of cellular therapy. My PI doesn’t have that expertise, so when I came to him with this idea, he said I should talk to Mark Sellmyer in the bioengineering department. He does a lot of cellular therapies, cell engineering, protein engineering and things of that nature. So his lab is more biological. 

I don’t have a grant for my research, so my advisors are supporting it out of their own pockets. They could have said, no, you need to work on this project that’s already going on in the lab. But they gave me the intellectual freedom to do what I wanted to do.”

Could Psychedelics Simultaneously Treat Chronic Pain and Depression?

Ahmad Hammo

Ongoing clinical trials have demonstrated that psychedelics like psilocybin and LSD can have rapid and long-lived antidepressant and anti-anxiety effects. A related clinical problem is chronic pain, which is notoriously difficult to treat and often associated with depression and anxiety.

This summer, Ahmad Hammo, a rising third-year student in bioengineering in the School of Engineering and Applied Science, is conducting a pilot study to explore psilocybin’s potential as a therapy for chronic pain and the depression that often accompanies it.

“There’s a strong correlation between chronic pain and depression, so I’m looking at how a psychedelic might be used for treating both of these things simultaneously,” says Hammo, who is originally from Amman, Jordan.

Hammo is working under the guidance of neuroanesthesiologist and neuroscientist Joseph Cichon, an assistant professor in the Perelman School of Medicine. The effort is supported by the Penn Undergraduate Research Mentoring (PURM) program, administered by the Center for Undergraduate Research and Fellowships, which awards undergraduate students $5,000 to spend 10 weeks conducting research alongside Penn faculty.

Hammo’s project focuses on neuropathic pain, pain associated with nerve damage. Like other forms of chronic pain, most experts believe that chronic neuropathic pain is stored in the brain.

“Neuropathic pain can lead to a centralized pain syndrome where the pain is still being processed in the brain,” Cichon says. “It’s as if there’s a loop that keeps playing over and over again, and this chronic form is completely divorced from that initial injury.”

Student Summer Research Spotlight: Dahin Song

Dahin Song
Dahin Song (BE 2024)

Dahin Song, a third year undergraduate student in Bioengineering, penned a guest blog post for Penn Career Services as part of their ongoing series of posts by recipients of the 2022 Career Services Summer Funding Grant. In this post, Song talks about her opportunity to conduct research in the SMART Lab of Daeyeon Lee, Professor and Evan C. Thompson Term Chair for Excellence in Teaching in the Department of Chemical and Biomolecular Engineering and member of the Penn Bioengineering Graduate Group. During her summer research, Song worked on increasing the stability of the monolayer in microbubbles, gas particles which have been put to therapeutic use. She writes:

“My project was on increasing the stability of the monolayer using cholesterol; theoretically, this would decrease the permeability while maintaining the fluidity of the monolayer. Being given my own project at the get-go was initially intimidating; initial learning curve was overwhelming – along with new wet lab techniques and protocols, I learned a whole new topic well enough to ask meaningful questions. But in retrospect, throwing myself headlong into a project was the best method to immerse me in the research environment, especially as a first-time researcher. I learned how to read papers efficiently, troubleshoot research problems, navigate in a laboratory environment, and be comfortable with working independently but more importantly, with others.”

Fourth year undergraduate Jerry Gao (BE ’23) is the latest student featured in 34th Street Magazine’s “Ego of the Week” series. Jerry, who hails from Coppell, TX, majors in Bioengineering with a minor in Asian American Studies. In addition to his academic studies, he is passionate about education and literacy, working with The Signal, the Asian Pacific American Leadership Initiative, and the Penn Reading Initiative. In this Q&A, he discusses the sense of community that brought him to Penn, the love of cooking (and gifting food to his friends) that powers his @gaos_chows Instagram account, and his experience as a student and now TA in Penn Bioengineering’s “BE MAD” lab class:

“Now that you’re on your way to graduating, what have been your favorite classes or experiences in Bioengineering or Asian American Studies?

‘In terms of bioengineering, there’s definitely a clear favorite that I have. It’s actually the class I’m a TA for right now. It’s “Bioengineering Modeling, Analysis, and Design,” and it’s basically the lab that all junior bioengineers take. There’s one particular lab we do in the class that always catches everyone’s attention; it’s called the cockroach lab. I think it’s one of the biggest reasons why people want to study bioengineering at Penn in particular.

It’s a segue into prosthetics and different medical devices that can help restore people’s limb functions. We order hundreds of cockroaches and then we put them in a little bit of an ice bath to anesthetize. We amputate their legs, which will essentially serve as our prosthetics, and then implant metal electrodes into two different spots of the leg. Then, we go into our computer program and type different lines of code that can help replicate different signal waves to move the legs. If you submit a wave with a particular frequency and particular amplitude, it’ll cause a leg to move in one direction, and if you do a different combination of the amplitude and frequency, it’ll cause it to move in the other direction. The next task is to trace the end of the leg and try to choreograph the leg to spell the letters B and E for bioengineering. It’s so fun to be able to see what combination of leg movements in the servo motor can form the backbone of the B for example, what can form the three lines of the E. I would say that’s probably my favorite moment in the bioengineering department.'”

“You get what you put in”: A First-generation Penn Bioengineering Graduate Student Discusses His Journey

Joseph Lance Casila

Joseph Lance Casila, a doctoral student and Fontaine Fellow in Bioengineering, was profiled by his alma mater, the University of Guam (UOG. Casila was the first person in his family to graduate from a U.S.-accredited university and is now studying tissue engineering and regenerative medicine in the Bioengineering and Biomaterials Laboratory of Riccardo Gottardi, Assistant Professor in Bioengineering in Penn Engineering and Pediatrics in Penn Medicine and the Children’s Hospital of Philadelphia (CHOP). His research in the Gottardi lab employs “tissue engineering and drug delivery for biomedical problems relating to knees, ears, nose, and throat but specifically to pediatric airway disorders.” The article discusses Casila’s journey from valedictorian of his high school, to a first-generation undergraduate interested bioengineering, and now a graduate student studying at Penn on a full scholarship. After completing his degree, Casila hopes to bring what he’s learned back home to advance health care in Guam.

“My mentors, and especially my friends, helped me make the most of what UOG had to offer, and it paid off rewardingly,” he said. “You get what you put in.”

Looking Towards the Future Through an Interdisciplinary Lens

by Erica K. Brockmeier

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.”

Student Spotlight: Sonia Bansal

Sonia Bansal, Ph.D.

Next up in the Penn Bioengineering student spotlight series is Sonia Bansal. Sonia got her B.S. in Biomedical Engineering at Columbia University in 2014. She then came to Penn, where she recently got her Ph.D. in September of 2020 in Bioengineering under the advisement of Robert Mauck, Mary Black Ralston Professor of Orthopaedic Surgery and Professor of Bioengineering. Her dissertation is entitled “Functional and Structural Remodeling of the Meniscus with Growth and Injury” and focuses on the ways the knee meniscus changes while being actively loaded (growth) and under aberrant loading (injurious) conditions. She has presented her work internationally and has first authored four papers, with two more in preparation. She is passionate about K-12 STEM outreach and teaching at the collegiate level. She has been on the teaching team for six classes in the department, and is the first recipient of the Graduate Fellowship for Teaching Excellence from the Bioengineering department.

What drew you to the field of Bioengineering?
I first got interested in Bioengineering when I realized that it would let me merge my interests in biology and the human body with my desire to solve big questions by building and creating solutions. I applied to college knowing it was what I wanted to study.

What kind of research do you conduct, and what is the focus of your thesis?
My research is focused on the knee meniscus, specifically the impacts of its complex extracellular matrix and how that matrix changes during growth and after meniscal injury. My interests are largely translational, and in the future, I’d like to think about how we can use preclinical animal models to create effective therapeutics and drive clinical decision making in the orthopedic space.

What did you study for your undergraduate degree? How does it pair with the work you’re doing now, and what advice would you give to your undergraduate self?
I studied Biomedical Engineering during my undergraduate education and worked in cartilage tissue engineering. These experiences helped guide me to my Ph.D. work here at Penn. The two pieces of advice I’d give my undergraduate self is to ask for help and that it’s important to get more than five hours of sleep a night.

What’s your favorite thing to do on Penn’s campus or in Philly?
My favorite thing to do on campus was to read papers/write lectures/work on grants at a local coffee shop. I used to go to HubBub when it still existed, Saxby’s, and United By Blue.

Have you done or learned anything new or interesting during quarantine?
I have embarked on a journey in culinary fermentation (variety of pickles and sourdough, of course), and recently started homebrewing!
