Bella Mirro, a fourth year student in Bioengineering who also minors in Chemistry, spoke with 34th Street Magazine about her many roles at Penn, including being Co–President of Shelter Health Outreach Program (SHOP), a Research Assistant in lab of Michal A. Elovitz, the Hilarie L. Morgan and Mitchell L. Morgan President’s Distinguished Professor in Women’s Health at Penn Medicine, and a Penn Engineering Council Marketing Team Member. In this Q&A, she discusses her research in women’s health and her passions for accessible healthcare, serving Philadelphia’s homeless community, and good food.

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,”
Retreat participants in Mitchell Hall at the College of Physicians
This year, the lineup of new student orientation activities included a new event: the first bioengineering retreat for incoming Ph.D. graduate students. Sitting in the historic Mitchell Hall at the College of Physicians, the 2022 Ph.D. cohort participated in a fun and educational half-day program that included a series of bonding activities, small-group conversations, and panel discussions. Current members of the Graduate Association of Bioengineers (GABE) planned the program to strengthen personal connections among students and to lend some advice to the newcomers as they embarked on their scholastic journey.
Prior to the retreat, participants read The Immortal Life of Henrietta Lacks by Rebecca Skloot, a work that delves into the human story of Henrietta Lacks, a Black woman from Virginia whose cancer cells were obtained for scientific study in the early 1950s without her knowledge. Today, “HeLa” cells have become one of the most significant tools in cell biology, enabling the development of polio vaccines, research into radiation effects, and even research on COVID-19. Together at the retreat, we discussed the intersection of ethics and scientific discovery, and reflected on our responsibility as scientists to consider the impact of our work beyond the immediate scientific question.

Current Ph.D. students volunteered their afternoons to share in two additional activities. Aoife O’Farrell, David Mai, Lasya Sreepada, and Mosha Deng imparted sage advice about using on-campus resources, handling advisor-advisee conflicts, and finding the best bites in Philly in the “Surviving the Ph.D. 101” panel discussion. Seven other students presented a series of flash talks about their research areas and musings on the best hypothetical mascot to represent their lab. The afternoon finished with an after-hours visit to the Mütter Museum, which holds an extensive and unique collection of anatomical specimens and antique medical equipment previously used for medical education.
If the WhatsApp group formed by the new cohort during the event is any indication, the retreat was an overall success! GABE looks forward to continuing the event in the future.

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.”
Yi-An Hsieh, a fourth year Bioengineering student from Anaheim, California, worked remotely this summer on a team that spanned three labs, including the Kamoun Lab at the Hospital of the University of Pennsylvania. Hsieh credits her research on kidney graft failure with enriching her scientific skill set, exposing her to machine learning and real-time interaction with genetic datasets. In a guest post for the Career Services Blog, Hseih writes about her remote summer internship experience. “It showed me that this type of research energy that could not be dampened despite the distance,” she writes.
