Twin academics Dani S. Basset, J. Peter Skirkanich Professor and director of the Complex Systems Lab, and Perry Zurn, a professor of philosophy at American University, were recently featured as guests on NPR radio show “Detroit Today” to discuss their new book, “Curious Mind: The Power of Connection.”
In their book, Basset and Zurn draw on their previous research, as well as an expansive network of ideas from philosophy, history, education and art to explore how and why people experience curiosity, as well as the different types it can take.
Basset, who holds appointments in the Departments of Bioengineering and Electrical and Systems Engineering, as well as the Department of Physics and Astronomy in Penn Arts & Science, and the Departments of Neuroscience and Psychiatry in Penn Perelman’s School of Medicine, and Zurn spoke with “Detroit Today” producer Sam Corey about what types of things make people curious, and how to stimulate more curiosity in our everyday lives.
According to the twin experts, curiosity is not a standalone facet of one’s personality. Basset and Zurn’s work has shown that a person’s capacity for inquiry is very much tied to the overall state of their health.
“There’s a lot of scientific research focusing on intellectual humility and also openness to ideas,” says Bassett. “And there are really interesting relationships between someone’s openness to ideas, someone’s intellectual humility and their curiosity and also their wellbeing or flourishing,”

Koo shared findings from one of his recent studies conducted in collaboration with Penn Engineering, which showed that a shapeshifting robotic microswarm can brush and floss teeth.
“Routine oral care is cumbersome and can pose challenges for many people, especially those who have a hard time cleaning their teeth” says Koo. “You have to brush your teeth, then floss your teeth, then rinse your mouth; it’s a manual, multistep process. The big innovation here is that the robotics system can do all three in a single, hands-free, automated way.”
The building blocks of these microrobots are iron oxide nanoparticles that have both catalytic and magnetic activity. Using a magnetic field, researchers could direct their motion and configuration to form either bristlelike structures that sweep away dental plaque from the broad surfaces of teeth, or elongated strings that can slip between teeth like a length of floss.
“Nanoparticles can be shaped and controlled with magnetic fields in surprising ways,” says Edward Steager, a senior research investigator at Penn Engineering and co-corresponding author. “We form bristles that can extend, sweep, and even transfer back and forth across a space, much like flossing. The way it works is similar to how a robotic arm might reach out and clean a surface. The system can be programmed to do the nanoparticle assembly and motion control automatically.”

In an interview with Quanta Magazine, Vijay Balasubramanian discusses his work as a theoretical physicist, noting his study of the foundations of physics and the fundamentals of space and time. He speaks of the importance of interdisciplinary study and about how literature and the humanities can contextualize scientific exploration in the study of physics, computer science, and neuroscience.
Balasubramanian is Cathy and Marc Lasry Professor in the Department of Physics and Astronomy in the Penn School of Arts and Sciences and a member of the Penn Bioengineering Graduate Group.
Our body’s natural line of defense against infection and disease, as well as cancer, is our immune system equipped with T cells, a type of white blood cell that determines how we react to foreign substances, or antigens, in the body. While we have an arsenal of T cells to protect us from these various infections, some people lack certain T cells or simply do not have enough to fight off infections, such as the flu or HIV, or defend against the body’s own mutated cancer cells.
Understanding the diversity of T cells and which antigens they target can provide insight into developing personalized immunotherapy to help those patients with weak spots or gaps in their T cell community. Jenny Jiang, Peter and Geri Skirkanich Associate Professor of Innovation in Bioengineering, is characterizing this diversity.
Jiang recently received a Cancer Research Institute’s (CRI) Lloyd J. Old STAR grant to support her research on this topic. The CRI STAR grant identifies mid-career “Scientists TAking Risks” in innovative cancer immunotherapy research areas, providing freedom and flexibility to pursue high-risk, high-reward research with financial support of $1.25 Million over the course of five years.
Jiang spoke with CRI science writer Arthur Brodsky about her research and how the STAR grant will support it.
“In our studies of healthy individuals, who have some natural immune protection against commonly encountered viruses like the flu, we noticed that not everyone has T cells that cover all the possible antigens,” says Jiang. “There are differences in the number and types of flu-targeting T cells that each individual has. For some “exotic” antigens, like those of HIV for example, although the general population doesn’t actually have exposure to them, they should still have a very low level of minimum T cells that can offer some protection from possible future infection. So that part of our T cell arsenal acts as a safety net. But some individuals may completely lack those T cells. In those cases, as you can imagine, those people will have a hard time overcoming a future infection.”
Jiang describes how this is similar to how our bodies prevent cancerous tumor growth.
Thomas A.V. Cassel, Practice Professor in Mechanical Engineering and Applied Mechanics in the School of Engineering and Applied Science, recently sat down with Dayo Adetu (BSE 2019, MSE 2021), President of the Penn Graduate Association of Bioengineers (GABE), to give his insight into engineering entrepreneurship.

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.”
Penn Engineering students (clockwise) Nyasha Zimunhu, Fahmida Lubna, Celestina Saven, Sanjana Hemdev, Sabrina Green and Sydney Kariuki all participated in the “I Look Like an Engineer” campaign, locally organized by AWE.
Penn Engineering’s Advancing Women in Engineering (AWE) program, dedicated to recruiting, retaining and promoting all female-identified students in the School, participated in the “I Look Like an Engineer” social media movement for the third year in a row. The movement, aimed at promoting diversity around underrepresented groups like women and people of color, was started by software developer Isis Anchalee in 2015.
Francesca Cimino
Francesca Cimino, member of AWE and a rising senior in the Department of Bioengineering, has always been passionate about changing the stereotypes and breaking down the barriers that prevent engineers of diverse backgrounds from thriving. She wanted to continue AWE’s tradition of participating in the movement to showcase the diversity already present within the field and prove that there is no single characteristic that defines an engineer.
At the conclusion of the campaign, Cimino responded to questions about the importance of diversity and what a more equal world in engineering looks like.
Why did you decide to get involved with AWE?
I applied to be a part of AWE’s Student Advisory Board during the spring semester of my freshman year. Being on the board was very enticing to me because I was looking to make connections with more women engineers at the time. I wanted to create my own community of women engineers while also wanting to help foster a community for all. AWE’s message and goals really resonated with me as well, so I knew it would be a perfect fit.
How important has mentorship from other female engineers been for you?
Being able to interact and learn from women who have experience in the industries I am most interested in has been very valuable to me. It has been inspiring to learn about their stories and the fact that I can relate to many of them has definitely allowed me to become more confident as I get closer to starting my career. Mentorship is something AWE really values and the board has worked to develop a mentoring network for women engineers, which I really admire.

César de la Fuente, Presidential Assistant Professor in Bioengineering, Chemical and Biomolecular Engineering, Microbiology, and Psychiatry, was the inaugural recipient of the Nemirovsky Engineering and Medicine Opportunity (NEMO) Prize from Penn Health-Tech in 2020 for his low-cost, rapid COVID test. Now with promising results recently published in the journal Matter (showing 90 percent accuracy in as little as four minutes), Penn Health-Tech caught up with de la Fuente to discuss his experience over the past year:
“How did [your project] evolve in the past year?
‘We started with one prototype and now have three entirely different prototypes for the test. Two use electrochemistry, and we are now working on a new technology that uses calorimetry. With calorimetry, when the cotton swabs are exposed to the virus, they change color. This means users are able to see if they’re affected by a virus through a simple color change, making it more of a visual detection method.'”
Electromagnetic fields are everywhere, and especially so in recent years. To most of us, those fields are undetectable. But a small number of people believe they have an actual allergy to electromagnetic fields. Ken Foster, a Professor Emeritus of Bioengineering, has heard these arguments before. “Activists would point to all these biological effects studies and say, ‘There must be some hazard’; health agencies would have meticulous reviews of literature and not see much of a problem.”
