Last year marked not just the 50th anniversary of the Department of Bioengineering (BE) but the 10th anniversary of Bioengineer-Teach-Aspire (BETA) Day, one of the most beloved and impactful programs run by the Graduate Association of Bioengineers (GABE).

BETA Day, an annual event in which a diverse group of Philadelphia middle school students learns about bioengineering and a variety of science, technology, engineering and math (STEM) fields from BE graduate students, has grown into an institution, one whose impact no one could have foreseen.

GABE’s original goal was to provide social opportunities for BE graduate students. While this is still an important function of the group, in the mid-2010s, students and board members found themselves looking for opportunities to provide more formalized outreach and mentorship. They wanted to have an impact on Philadelphia and cultivate the next generation of bioengineers.

The Seeds of BETA Day

Benjamin Freedman, a principal investigator at Beth Israel Deaconess Medical Center, Assistant Professor of Orthopedic Surgery at Harvard Medical School, and founder of biotech startup Limax Biosciences, earned his doctorate in Bioengineering in the lab of Louis Soslowsky, Fairhill Professor in the Department of Orthopaedic Surgery within the Perelman School of Medicine (PSOM) and in Bioengineering within the School of Engineering and Applied Science (Penn Engineering). Freedman played a key role in BETA Day’s founding. 

In 2009, Freedman, then an undergraduate at the University of Rochester, attended a talk at the City College of New York (CCNY), which sparked his interest in mentorship. Sheldon Weinbaum, a Distinguished Professor in Biomedical and Mechanical Engineering at CCNY and the Biomedical Engineering Society (BMES) inaugural diversity award winner, spoke about “fulfilling the dream” of mentorship and the struggle for inclusion in STEM fields, echoing the language of Martin Luther King Jr. 

Inspired by this encounter, Freedman got involved with a mentorship program during his senior year. He later signed up for a lunch with Weinbaum to talk about mentorship. Freedman recalls that Weinbaum’s face “lit up” when he realized that this student didn’t just want to talk science but was genuinely interested in inclusion, diversity and mentorship.

Arriving at Penn Engineering and PSOM for graduate school in 2011, Freedman joined GABE, bringing this passion and experience with him and helping GABE to shape and clarify their outreach and mentorship programs. 

From Campus to Community

Along with other GABE board members, such as Cori Riggin and Shauna Dorsey, Freedman worked over the course of a year and a half to identify the mentorship needs within BE and gauge student interest. David Meaney, Solomon R. Pollack Professor and then Chair of BE, and former BE faculty Susan Margulies, now Professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, were particularly involved in these discussions.

The GABE board reorganized to include mentorship and outreach chairs, and eventually started a formal mentorship program in partnership with the Penn undergraduate Biomedical Engineering Society (BMES). The mentorship program continues to this day, creating opportunities for BE graduate students to engage with undergraduate concerns through one-on-one meetings to discuss career or graduate school advice, summer BBQ’s, roundtable discussions and monthly meetups.

With an internal mentorship program established, the team turned their focus to Philadelphia. Initially, GABE established a partnership with iPraxis, a local STEM education non-profit, to do some outreach activities in middle schools. This partnership resulted in an Outstanding Outreach Award from the national Biomedical Engineering Society in 2014. But with the department’s 40th anniversary approaching, GABE’s members wanted to do something spectacular to celebrate and give back to the community.

Service Learning in Action

By then, Ocek Eke, Director of Graduate Students Programming at Penn Engineering, had been recently appointed Director of Global and Local Service Learning Programs. Eke provided Freedman and GABE advice on setting up effective outreach programs and to determine what resources the School could contribute. “We have a role to play to fulfill our mission,” Eke says, citing Penn’s motto, “Leges Sine Moribus Vanae,” which translates to “Laws without morals are useless.”

GABE’s efforts were part of a “wave” of interest in outreach and community service in both the department and the School, Eke remembers, including the undergraduate group Access Engineering and several service learning courses which took students to Asia, Africa and Central America. He was impressed by the lack of cynicism in the BE student body. “These are students who saw a need, who are passionate about what they want to achieve. They could have just been comfortable but were willing to go and stick their necks out. They used the resources we have here in Penn Engineering to address these needs.”

A (BETA) Day to Remember

The first BETA Day took place at the Singh Center for Nanotechnology, which had only just opened. Held with the enthusiastic participation of around 70 middle schoolers, and almost as many volunteers, the event included a full day of programming, with representation from every Penn Engineering department. There were science talks, workshops, and even a drone demo with Vijay Kumar, Nemirovsky Family Dean of Penn Engineering. The entire day was student-driven and staffed by volunteers, demonstrating the students’ commitment to making a difference.

GABE never imagined BETA Day as an annual event, but the first instance was so successful, it became hard to imagine not repeating it. Ten years later, the GABE board continues to introduce bioengineering to a diverse and ambitious group of middle schoolers every spring. 

In recent years, the location has shifted to other venues, including Pennovation Works, in Gray’s Ferry, and BE’s own education lab, the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace. Penn’s General Robotics, Automation, Sensing and Perception (GRASP) Lab has also become a key collaborator in BETA Day. 

In 2021, during the COVID-19 lockdown, the industrious and creative GABE board even tailored BETA Day activities to be held in an entirely virtual environment. “These types of events are not as successful when they’re only initiated by faculty,” says Freedman. Generating and sustaining student involvement has been a cornerstone of BETA Day’s continued success.

The Legacy of BETA Day

GABE’s mentorship efforts have grown as well, changing to meet evolving student needs. The mentorship program now involves students being placed in “families” of around four undergraduates and two graduate students, spanning a range of class years and experience levels. A third student association, the Master’s Association in Bioengineers (MAB), was established to better foster community and facilitate opportunities for master’s students.  

The department also launched an applicant support program in 2020, enhancing BE’s mission of increasing diversity, equity and inclusion by pairing Ph.D. applicants to current doctoral students, who serve as mentors to help navigate the admissions process, giving feedback on application materials and providing other support to prospective students.

Structures of support and outreach activities like BETA Day have become a key emphasis of the department’s graduate student recruitment, helping to attract students who value the department’s core mission and increasing opportunities for underserved or underrepresented communities.

The legacy of that original BETA Day also continues in Freedman’s Lab. After graduating in 2017, having served on the GABE board and as President from 2015-2016, Freedman continued to mentor over 20 students during his postdoctoral research at Harvard. He is now building his own independent lab where diversity, mentorship and outreach are foundational pillars.

A Nebula of Inspiration

Perhaps the most consequential impact of BETA Day is the impression it makes on the middle schoolers who participate each year. “To really get to know what happens on BETA Day and what it’s true impact is, you need to experience it,” says Ravi Radhakrishnan, Herman P. Schwan Chair of the Department of Bioengineering and Professor in Bioengineering and in Chemical and Biomolecular Engineering.

“I walked into the Stephenson Foundation Education Lab during BETA Day 2024,” recalls Radhakrishnan, “and what I saw was teams of teenagers tinkering with pipes that were clogged, strategizing on unclogging them without damaging them: an assignment that got them thinking in teams about how to prevent heart attacks. 

“Expose these young minds to design thinking, versatile tools, and critical problems in biomedical engineering, and the elegant solutions they brainstorm are truly mind blowing. BETA Day is like the nebula where future biomedical stars are born.”

2022 Career Award Recipient: Michael Mitchell

Michael Mitchell, J. Peter and Geri Skirkanich Assistant Professor of Innovation in the Department of Bioengineering, is one of this year’s recipients of the National Science Foundation’s CAREER Award. The award is given to early-career faculty researchers who demonstrate the potential to be role models in their field and invest in the outreach and education of their work.

Mitchell’s award will fund research on techniques for “immunoengineering” macrophages. By providing new instructions to these cells via nanoparticles laden with mRNA and DNA sequences, the immune system could be trained to target and eliminate solid tumors. The award will also support graduate students and postdoctoral fellows in his lab over the next five years.

The project aligns with Mitchell’s larger research goals and the current explosion of interest in therapies that use mRNA, thanks to the technological breakthroughs that enabled the development of COVID-19 vaccines.

“The development of the COVID vaccine using mRNA has opened doors for other cell therapies,” says Mitchell. “The high-priority area of research that we are focusing on is oncological therapies, and there are multiple applications for mRNA engineering in the fight against cancer.”

A new wave of remarkably effective cancer treatments incorporates chimeric antigen receptor T-cell (CAR-T) therapy. There, a patient’s T-cells, a type of white blood cell that fights infections, are genetically engineered to identify, target and kill individual cancer cells that accumulate in the circulatory system.

However, despite CART-T therapy’s success in treating certain blood cancers, the approach is not effective against cancers that form solid tumors. Because T-cells are not able to penetrate tumors’ fibrous barriers, Mitchell and his colleagues have turned to another part of the immune system for help.

How a Diversity Program Enabled a Childhood Orthopaedics Patient’s Research Dreams

by Julie Wood

As a child, Sonal Mahindroo would go to her orthopaedics appointments with her family, slowly becoming more and more fascinated by the workings and conditions of the musculoskeletal system. While being treated for scoliosis, she would receive children’s books from her doctor that helped provide clear and simplified explanations of orthopaedic topics, which supported her interest.

Nearly a decade later, Mahindroo is still interested in expanding her orthopaedic knowledge, and a Penn Medicine program is helping fuel that expansion. Now a senior at St. Bonaventure University in New York, Mahindroo spends her time at the university’s lab. But in addition to that, this year, she was able to take part in more learning opportunities with Penn Medicine’s support, via the McKay Orthopaedic Research Lab’s Diversity, Equity, and Inclusion (DEI) committee’s conference grant program.

McKay’s DEI committee — consisting of faculty, post-docs, graduate students, and staff — offers a welcoming environment and resources that support people of all identities, empowering them to bring forward unique perspectives to orthopaedic research.

“Our goal is to improve diversity and culture both within McKay and in the orthopaedic research community outside of Penn,” said Sarah Gullbrand, PhD, a research assistant professor at the McKay Lab. “We wanted to provide an opportunity for students to attend a conference and make connections to help them pursue their interest in orthopaedic research.”

The McKay conference grant supports undergraduate students who have been unable to get hands-on research experience. Participants are provided with the opportunity to network with leaders in the field of orthopaedic research, listen to cutting-edge research presentations, and learn about ways to get involved in orthopaedic research themselves.

“When launching the conference grant program earlier this year, I was motivated by my own experience attending a conference as an undergraduate. That experience really increased my interest in attending graduate school and taught me a lot about the breadth of research in orthopaedics,” said Hannah Zlotnick, a PhD student at the McKay Lab and member of the DEI committee. Through the McKay Conference Grants, the committee has supported two cohorts of students. “So far, we’ve been able to fund 11 undergraduate students from around the country to virtually attend orthopaedics conferences and receive early exposure to careers in STEM.”

Along with the conference grant, the McKay Lab holds workshops, book clubs, and other programs focused on DEI-related topics. As part of their efforts for promoting gender diversity in the field, the McKay Lab has previously partnered with the Perry Initiative to offer direct orthopaedic experiences for girls in high school, where they can learn how to suture, and perform mock fracture fixation surgeries on sawbones.

As a primarily male-populated field, orthopaedics could benefit greatly from diversity efforts. While women comprise approximately 50 percent of medical school graduates in the United States, they represent only 14 percent of orthopaedic surgery residents.

“The only women on staff at my orthopaedist’s office were receptionists. There were no female physicians or engineers to make my scoliosis brace,” Mahindroo said. “It was really cool coming to the McKay Lab and seeing how much the field has progressed since then.”

Susan Margulies, Professor Emeritus in Bioengineering, has been selected to lead the National Science Foundation’s (NSF) Directorate of Engineering, “the first biomedical engineer to head the directorate.” Margulies is chair of the Wallace H. Coulter Department of Biomedical Engineering at the Georgia Institute of Technology and Emory University. She earned her master’s and doctoral degrees from Penn Bioengineering before joining the department as an Assistant Professor in 1993.

In a press release from Emory University, Margulies stated that, “The opportunity to serve the NSF resonates with my values — catalyzing impact through innovation, rigor, partnership, and inclusion.” The announcement continues:

“Building on initiatives she developed at the University of Pennsylvania, Margulies prioritized career development for faculty and Ph.D. graduates during her years leading Coulter BME. She added dedicated staff to help doctoral students prepare for increasingly popular career paths outside of academia. The department increased the diversity of Ph.D. students and improved faculty diversity at all ranks during her tenure. Margulies oversaw hiring of 20 new faculty members and launched formalized mentoring for early career professors, including creating a new associate chair position dedicated to faculty development.”

Margulies will step down from her position as chair in Coulter BME though she will remain in the Georgia Tech and Emory faculty. Her Injury Biomechanics Lab studies “the influence of mechanical factors on the structure and function of human tissues from the macroscopic to microscopic level, with an emphasis on the brain and lungs.”

2021 CAREER Award recipient: Alex Hughes, Assistant Professor in Bioengineering

The National Science Foundation’s CAREER Award is given to early-career researchers in order to kickstart their careers in innovative and pivotal research while giving back to the community in the form of outreach and education. Alex Hughes, Assistant Professor in Bioengineering and in Cell and Developmental Biology, is among the Penn Engineering faculty members who have received the CAREER Award this year.

Hughes plans to use the funds to develop a human kidney model to better understand how the development of cells and tissues influences congenital diseases of the kidney and urinary tract.

The model, known as an “organoid,” is a lab-grown piece of human kidney tissue on the scale of millimeters to centimeters, grown from cultured human cells.

“We want to create a human organoid structure that has nephrons, the filters of the kidney, that are properly ‘plumbed’ or connected to the ureteric epithelium, the tubules that direct urine towards the bladder,” says Hughes. “To achieve that, we have to first understand how to guide the formation of the ureteric tubule networks, and then stimulate early nephrons to fuse with those networks. In the end, the structures will look like ‘kidney subunits’ that could potentially be injected and fused to existing kidneys.”

The field of bioengineering has touched on questions similar to those posed by Hughes, focusing on drug testing and disease treatment. Some of these questions can be answered with the “organ-on-a-chip” approach, while others need an even more realistic model of the organ. The fundamentals of kidney development and questions such as “how does the development of nephrons affect congenital kidney and urinary tract anomalies?” require an organoid in an environment as similar to the human body as possible.

“We decided to start with the kidney for a few reasons,” says Hughes. “First, because its development is a beautiful process; the tubule growth is similar to that of a tree, splitting into branches. It’s a complex yet understudied organ that hosts incredibly common developmental defects.

“Second,” he says, “the question of how things form and develop in the kidney has major medical implications, and we cannot answer that with the ‘organ-on-a-chip’ approach. We need to create a model that mimics the chemical and mechanical properties of the kidney to watch these tissues develop.”

The fundamental development of the kidney can also answer other questions related to efficiency and the evolution of this biological filtration system.

“We have the tendency to believe that systems in the human body are the most evolved and thus the most efficient, but that is not necessarily true,” says Hughes. “If we can better understand the development of a system, such as the kidney, then we may be able to make the system better.”

Hughes’ kidney research will lay the foundation for broader goals within regenerative medicine and organ transplantation.

Bioengineering Graduate Students Take the Annual BETA Day Online

By GABE Outreach Chairs and Ph.D. students David Gonzalez-Martinez and David Mai

BETA Day Biomaterials workshop

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.

Dayo Adetu, Bioengineering Master’s student and GABE President, teaches the students about Genetic Engineering

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.

Bioengineering Student Jamie Moni Participates in the 34th Africana Studies Summer Institute

Jamie Moni (BAS 2024)

Jamie Moni, a freshman in Penn’s Department of Bioengineering, spent his summer before starting Penn participating in the 2020 Africana Studies Summer Institute, a pre-freshman program hosted by the Center for Africana Studies. A recent piece by Penn Today’s KristineGarcía profiling the thirty-four-year-old program and its transition to a virtual format featured Moni’s thoughts on the program:

“Jamie Moni is a bioengineering major who participated from his home in Hillsborough, New Jersey. The Institute was one of the first programs he sought out after enrolling at Penn, Moni says. ‘My parents were really happy that there’s a program like this at Penn, especially because there’s not a lot of Black people in my town. Most of the African Americans that I interact with on a daily basis are my family,’ Moni says, whose ancestry is from Cameroon. ‘It’s been interesting, to say the least.’

Moni has a close relationship with his peer mentor, Niko Simpkins, who ‘has been really one of the best things that I took out of the Africana Institute.’ A fellow engineering major, Simpkins gives Moni study tips and introduced him to the National Society of Black Engineers as well as STEM-specific workshops.”

Connecting Communities Impacted by COVID-19

Three Penn seniors combine their desire to help with their unique skill sets to create Corona Connects, an online platform that connects volunteers with organizations in need of support.

Developed by (from left) Steven Hamel from the School of Engineering and Applied Science, Megan Kyne from the Wharton School, and Hadassah Raskas from the College of Arts & Sciences, Corona Connects bridges the gap between those looking for ways to help and organizations in need of support.

by Erica K. Brockmeier

With college campuses shut due to the novel coronavirus, many students with new-found time on their hands have found themselves asking, “What can I do to help?”

To connect people with organizations that need support, three students have combined their desire to help with the skills they’ve learned both inside and outside the classroom. Developed by Penn seniors Steven Hamel from the School of Engineering and Applied Science, Megan Kyne from the Wharton School, and Hadassah Raskas from the College of Arts & Sciences, the online platform Corona Connects bridges the gap between people looking for ways to help and organizations looking for support.

After returning to her hometown of Silver Spring, Maryland, Raskas was eager to find some way to help but noticed that it was difficult to find opportunities online. With friends and colleagues voicing similar struggles, Raskas reached out to University of Maryland junior Elana Sichel and started putting together a list of organizations in need of help. Then, after reaching out on the Class of 2020 Facebook page about the project, Hamel, from Philadelphia, and Kyne, from Pittsburgh, offered their support to get an online platform up and running.

The team of students quickly realized that there was both a large number of individuals who wanted to find ways to help alongside an unprecedented level of need from numerous types of organizations. “We knew there was need, and we knew there was an availability of people, but the connection was missing, so we built Corona Connects to bridge this gap,” says Raskas.
