Neurology, bioengineering, and physical medicine and rehabilitation might not seem like three disciplines that fit together, but for Flavia Vitale, an assistant professor of all three, it makes perfect sense. As the director and principal investigator at the Vitale Lab, her research focuses on developing new technologies that help to study how the brain and neuromuscular systems function.
Years ago, while she was working at Rice University developing new materials and devices that work in the body in a safer, more effective way, former president Barack Obama launched the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, aimed at revolutionizing the understanding of the human brain. This emphasis on how little is known about brain structure and function inspired Vitale to refocus her research on developing technology and materials that will help researchers solve the mysteries of the brain.
In 2018, she joined the faculty at the Perelman School of Medicine as an assistant professor of neurology, bioengineering, and physical medicine and rehabilitation, and founded the multidisciplinary Vitale Lab, where her team develops cutting edge materials and devices that will someday help clinicians diagnose and treat patients with complicated brain and neurological conditions. She is also one of the engineers looking forward to using new combined clinical/research facilities in neuroscience at Penn Medicine’s new Pavilion where new neurotechnoloigies will be developed and tested.
“My main goal is to create tools that can help solve mysteries of the brain, and address the needs of clinicians,” she says.
“My lab was recently awarded two grants totaling $4.5 million from the National Institute of Neurological Disorders and Stroke. In order to obtain more precise insights, noninvasively, into brain activity to improve gene therapy treatments for a range of diagnoses, from Parkinson’s disease to glioblastoma. The first grant is designated for the development of a novel surgical device for delivering gene-based therapeutics to the brain. The second is for optimization and pre-clinical validation of a novel EEG electrode technology, which uses a soft, flexible, conductive nanomaterial rather than metal and gels. We hope to confirm that these technologies work as well as, if not better than existing ones.”
Our next Penn Bioengineering seminar will be held on zoom next Thursday.

Abstract: Real-time microscopy of the dynamics of cells and tissues in 3D environments is opening new windows to understanding the biophysical mechanisms of complex biological processes. Direct visualization is allowing us to explore fundamental questions in more depth that include: How do cells migrate in 3D? How do cancer cells invade? How is the extracellular matrix assembled? How are organs formed? Visualizing how cells move and organize into tissues is not only providing descriptive insights, but is also leading to the identification of novel, unexpected physical and mechanical mechanisms relevant to tissue engineering. Cells can use varying combinations of cell adhesion to adjacent cells and to the surrounding extracellular matrix with localized cellular contractility to migrate, invade, and produce the complex tissue architecture needed for organ formation.
Kenneth Yamada Bio: Kenneth Yamada has been an NIH Distinguished Investigator since 2011. He received MD and PhD degrees from Stanford. He was a Section Chief at the National Cancer Institute for 10 years and has been a Section Chief at NIDCR since 1990. He is an elected Fellow of the AAAS and American Society for Cell Biology. His research focuses on discovering novel mechanisms and regulators of cell interactions with the extracellular matrix and their roles in embryonic development and cancer. His research group focuses on the mechanisms by which three-dimensional (3D) extracellular matrix mediates key biological events, including cell migration, tissue morphogenesis, and cancer cell invasion. His research places particular emphasis on characterizing the dynamic movements of cells and their extracellular matrix as tissues are remodeled in 3D in real time. The biological systems they study include human primary cells migrating in 3D, human tumor cells and tissues, and mouse organ development. He places particularly high priority on developing future independent research leaders.

Abstract: The most effective medicines are those that target the earliest causes of disease, rather than later manifestations. Engineering of biomolecules is a promising but underexplored approach to precisely detecting or targeting disease causes. I will present our work to develop a novel approach to treating cancer by detecting the signaling abnormalities that give rise to cancer. Interestingly, this effort involves biomolecular engineering at multiple scales: proteins, pathways, and viruses. I will also discuss how our work has translated serenditously to developing treatments for SARSCoV2.

The winners of the Medical Robots for Contagious Disease Challenge Award for Best Application (L to R): Yasmina Al Ghadban, Phuong Vu, and Rob Paslaski.
Three recent Penn Bioengineering graduates took home the Best Application Award from the Medical Robotics for Contagious Disease Challenge, part of the three-month Hamlyn Symposium on Medical Robotics. Organized by the Hamlyn Centre at Imperial College, London, UK, in collaboration with the UK-RAS Network, the challenge involved “creating a 2-minute video of robotic or AI technology that could be used to tackle contagious diseases” in response to the current and potential future pandemics. Yasmina Al Ghadban, Rob Paslaski, and Phuong Vu were members of the Penn Bioengineering senior design team rUmVa who designed and built a cost-effective, autonomous robot that can quickly disinfect rooms by intelligently sanitizing high-touch surfaces and the air. The Best Application Award comes with a prize of £5,000.
The full Team rUmVa (L to R): Yasmina Al Ghadban, Rachel Madhogarhia, Phuong Vu, Jeong Inn Park, and Rob Paslaski.
Team rUmVa, which also included Bioengineering seniors Rachel Madhogarhia and Jeong Inn Park, also received a Berkman Opportunity fund grant from Penn Engineering and was one of three teams to win Penn Bioengineering’s Senior Design competition. Senior Design work is conducted every year on-site in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace (which successfully reopened for in-person activities this Spring semester). Read the full list of Spring 2021 Senior Design Award Winners here.
rUmVa and the other challenge winners were honored during the Hamlyn Symposium’s virtual closing ceremony on July 29, 2021.
Read rUmVa’s abstract and final papers, along with those of all of the Penn Bioengineering Teams’, on the BE Labs Senior Design 2021 website. rUmVa’s presentation can be viewed on Youtube:
Shreya Parchure, a recent graduate of Penn Bioengineering, was selected by a committee of faculty for a 2021 Rose Award from the Center for Undergraduate Research and Fellowships (CURF). The Rose Award recognizes outstanding undergraduate research projects completed by graduating seniors under the supervision of a Penn faculty member and carries with it a $1,000 award. Parchure’s project, titled “BDNF Gene Polymorphism Predicts Response to Continuous Theta Burst Stimulation (cTBS) in Chronic Stroke Patients,” was done under the supervision of Roy H. Hamilton, Associate Professor in Neurology and Physical Medicine and Rehabilitation and director of the Laboratory for Cognition and Neural Stimulation in the Perelman School of Medicine. Parchure’s work in Hamilton’s lab previously resulted in a 2020 Goldwater Scholarship.
Michael Mitchell, Sarah Shepherd and David Issadore pose with their new device.
The COVID vaccines currently being deployed were developed with unprecedented speed, but the mRNA technology at work in some of them is an equally impressive success story. Because any desired mRNA sequence can be synthesized in massive quantities, one of the biggest hurdles in a variety of mRNA therapies is the ability to package those sequences into the lipid nanoparticles that deliver them into cells.
Now, thanks to manufacturing technology developed by bioengineers and medical researchers at the University of Pennsylvania, a hundred-fold increase in current microfluidic production rates may soon be possible.
The researchers’ advance stems from their design of a proof-of-concept microfluidic device containing 128 mixing channels working in parallel. The channels mix a precise amount of lipid and mRNA, essentially crafting individual lipid nanoparticles on a miniaturized assembly line.
This increased speed may not be the only benefit; more precisely controlling the nanoparticles’ size could make treatments more effective. The researchers tested the lipid nanoparticles produced by their device in a mouse study, showing they could deliver therapeutic RNA sequences with four-to-five times greater activity than those made by conventional methods.
The study was led by Michael Mitchell, Skirkanich Assistant Professor of Innovation in Penn Engineering’s Department of Bioengineering, and David Issadore, Associate Professor in Penn Engineering’s Department of Bioengineering, along with Sarah Shepherd, a doctoral student in both of their labs. Rakan El-Mayta, a research engineer in Mitchell’s lab, and Sagar Yadavali, a postdoctoral researcher in Issadore’s lab, also contributed to the study.
They collaborated with several researchers at Penn’s Perelman School of Medicine: postdoctoral researcher Mohamad-Gabriel Alameh, Lili Wang, Research Associate Professor of Medicine, James M. Wilson, Rose H. Weiss Orphan Disease Center Director’s Professor in the Department of Medicine, Claude Warzecha, a senior research investigator in Wilson’s lab, and Drew Weissman, Professor of Medicine and one of the original developers of the technology behind mRNA vaccines.
“We believe that this microfluidic technology has the potential to not only play a key role in the formulation of current COVID vaccines,” says Mitchell, “but also to potentially address the immense need ahead of us as mRNA technology expands into additional classes of therapeutics.”
Each year, Penn Engineering’s seniors present their Senior Design projects, a year-long effort that challenges them to test and develop solutions to real-world problems, to their individual departments. The top three projects from each department go on to compete in the annual Senior Design Competition, sponsored by the Engineering Alumni Society, which involves pitching projects to a panel of judges who evaluate their potential in the market. While the pandemic made this year’s competition logistically challenging, students and organizers were able to come together virtually to continue the tradition.
This year’s virtual format provided an opportunity for judges from around the country to participate in evaluating projects. Brad Richards, Director of Alumni Relations at Penn Engineering who helped plan the competition, was able to help recruit more than 60 volunteers to serve on the panel.
“The broad number of judges from varying industries made this competition incredibly meaningful, we will absolutely be integrating a virtual component to allow for more judges in the future.”
Eighteen teams total, three from each department, virtually presented to the panel of judges, who awarded $2,000 prizes in four categories.
Technology & Innovation Prize
This award recognized the team whose project represents the highest and best use of technology and innovation to leverage engineering principles.

She will bring these extensive skills to PHT and Penn Bioengineering in two new, hands-on graduate courses in medical innovation centered around Penn Health-Tech ventures.”
Each Penn Bioengineering (BE) student’s undergraduate experience culminates in Senior Design, a two-semester capstone project in which student teams conceive, design, and develop a bioengineering project, whether a medical device, molecular biological therapeutic, or research tool. Projects are inherently interdisciplinary, and can involve biomaterials, electronics, mechanics, molecular biology, nanotechnology, and microfluidics. Research and development is supervised by BE faculty, lab staff, and graduate student TA’s and project managers, and work is conducted in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace (which successfully reopened for in-person activities this Spring semester).
This year’s 11 teams included the variety and innovation we’ve come to expect from our outstanding students, ranging from devices which track medical conditions, such afib and POTS, to technology responding to our post-COVID world, such as a disinfecting robot and a kit to make telemedicine more effective. The year finished with presentations to alumni judges, and BE’s annual Demo Day (the only in-person demo day on the engineering campus this year) on April 15, 2021, in which students showcased their designs to faculty.
Several teams were highlighted for awards recognition.
