Penelope Georges, Ph.D.

“My time at Penn spoiled me for many job experiences that followed.  The Institute for Medicine and Engineering (IME) was collaborative, familial, and stimulating. During my Ph.D. work, I felt simultaneously nurtured and challenged.  Most credit for this prolific phase of my career is due to the members of Dr. Paul Janmey’s laboratory during my tenure at Penn – starting with the big man himself.  My research mentor promoted a research experience that centered on respect for others, not only within our field of study but also outside the academy.   Respect meant the expectation of forming strong relationships and collaborations and having reverence for scientific experts and practitioners alike.  The foundation of the lab’s ethos was collaboration for the greater good. 

Dr. Janmey set the tone for lab members to hold each other in high regard and to be team players.   I would not have been as successful without this support.  Beyond the lab, the IME at the time had a remarkable staff assistant in Marvin Jackson who was central to promoting camaraderie across the Institute.  Marvin was a critical presence in the IME and I believe that many scientific collaborations were made possible due to the environment he cajoled.

Outside the IME, some the most meaningful moments of my Ph.D. studies came from traveling outside the U.S. to collaborate internationally.  I was fortunate to travel as close as Mechanicsville, PA and as far as the Czech Republic to attend meetings, perform experiments, and make connections with colleagues.   Through travel and meeting many different types of people, I learned the culture of being in academia and developed a broader view of scientific research. 

As of recently, my career has focused on pedagogy in higher education.  At Princeton, I serve within an entity that has a central mission of improving science and engineering literacy for all its constituents: the Council on Science and Technology.  I develop new science and engineering courses and introduce interactive research-based teaching methods into these courses. I am involved in policy issues on STEM education at Princeton and beyond.  The skills I learned at Penn that are critical to my current position are to recognize problems and design innovative solutions and the ability to communicate and collaborate with researchers across many disciplines.  I am very grateful to be an alumna of a remarkable program.”

Shapeshifting Microrobots Can Brush and Floss Teeth

by Katherine Unger Baillie

In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque. (Illustration: Melissa Pappas)

A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one.

The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated way to perform the mundane but critical daily tasks of brushing and flossing. It’s a system that could be particularly valuable for those who lack the manual dexterity to clean their teeth effectively themselves.

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. In both instances, a catalytic reaction drives the nanoparticles to produce antimicrobials that kill harmful oral bacteria on site.

Experiments using this system on mock and real human teeth showed that the robotic assemblies can conform to a variety of shapes to nearly eliminate the sticky biofilms that lead to cavities and gum disease. The Penn team shared their findings establishing a proof-of-concept for the robotic system in the journal ACS Nano.

“Routine oral care is cumbersome and can pose challenges for many people, especially those who have hard time cleaning their teeth” says Hyun (Michel) Koo, a professor in the Department of Orthodontics and divisions of Community Oral Health and Pediatric Dentistry in Penn’s School of Dental Medicine and co-corresponding author on the study. “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.”

Kevin Johnson: Informatics Evangelist

by Ebonee Johnson

Kevin Johnson is used to forging his own path in the fields of healthcare and computer science.

A picture of Johnson as a child, from his children’s book “I’m a Biomedical Expert Now!”

If you ask him to locate his niche within these fields, Johnson, David L. Cohen and Penn Integrates Knowledge (PIK) Professor with appointments in Penn Engineering and the Perelman School of Medicine, would say “informatics.” But that doesn’t tell the whole story of the board-certified pediatrician, who has dedicated his career to innovations in how patients’ information is created, documented and shared, all with the goal of improving the quality of healthcare they receive.

Informatics, the study of the structure and behavior of interactions between natural and computational systems, is an umbrella term. Within it, there’s bioinformatics, which applies informatics to biology, and biomedical informatics, which looks at those interactions in the context of healthcare systems. Finally, there is clinical informatics, which further focuses on the settings where healthcare is delivered, and where Johnson squarely places himself.

“But you can just call it ‘informatics,’” says Johnson. “It will be easier.”

He mainly studies how computational systems can improve ambulatory care — sometimes known as outpatient care, or the kind of care hospitals give to patients without admitting them — in real time. If you’ve ever heard your doctor complain about the amount of time it takes them to input the information they get from you during your visit, or wondered why they need to capture this information during the visit in the first place, these are some of the questions Johnson is investigating.

“We’re taking care of patients but we’re getting frustrated by things that we thought these new computers should be able to fix,” says Johnson.” I think there’s a very compelling case for using engineering principles to reimagine electronic health records.”
