Faculty members in the Department of Bioengineering at the University of Pennsylvania are among the recipients of a major $9.25 million grant from the Paul G. Allen Family Foundation to study the mechanism underlying concussion and to investigate possible interventions.
David Meaney, PhD, Solomon R. Pollack Professor and Chair of the Bioengineering Department (above left), is one of two principal investigators, with Douglas H. Smith, MD, professor of neurosurgery at Penn’s Perelman School of Medicine (above right). In addition, Danielle S. Bassett, PhD, Eduardo D. Glandt Faculty Fellow and Associate Professor (below left), Dongeun (Dan) Huh, PhD, Wilf Family Term Assistant Professor (below center), and David Issadore, PhD, assistant professor (below right), all of BE Department, are co-investigators. The Allen Foundation grant also involves investigators from Columbia University (Barclay Morrison, Ph.D.), Duke University (Cameron Bass, Ph.D.), and Children’s Hospital of Philadelphia (Akiva Cohen, Ph.D.).
Selected from a large national pool of applicants, the Allen Foundation grant will bring together new technology platforms developed by Drs. Huh and Issadore to study how concussions occur at the microtissue scale and release markers of rewiring during recovery. Network theory models from Dr. Bassett’s group will provide an entirely new view on how concussion recovery occurs at all scales in the brain. The overall impact of the project will be to move away from the widely held perspective that all concussions should be treated identically and towards a view that concussions can follow several recovery pathways, some of which must be monitored closely in the days to weeks following injury.
When someone talks about using “your network” to find a job or answer a question, most people understand that to mean the interconnected web of your friends, family, and acquaintances. But we all have another key network that shapes our life in powerful ways: our brains.
In the brain, impulses whiz from one brain region to another, helping you formulate all of your thoughts and decisions. As science continues to unlock the complexities of the brain, a group of researchers has found evidence that brain networks and social networks actually influence and inform one another.
It found that people who show greater changes in connectivity in their mentalizing system during social exclusion compared to inclusion tend to have a less tightly knit social network — that is, their friends tend not to be friends with one another. By contrast, people with more close-knit social networks, in which many people in the network tend to know one another, showed less change in connectivity in their mentalizing regions.
The Department of Bioengineering at the University of Pennsylvania is proud to announce that Konrad Kording, PhD, currently professor of physical medicine and rehabilitation, physiology, and applied mathematics at Northwestern University, will join the BE faculty in the fall.
Dr. Kording, a neuroscientist with advanced degrees in experimental physics and computational neuroscience, is a native of Germany. After earning his PhD in 2001 at the Swiss Federal Institute of Technology in Zurich, he held fellowships at University College, London, and MIT before arriving at Northwestern in 2006.
Kording’s groundbreaking interdisciplinary research uses data science to understand brain function, improve personalized medicine, collaborate with clinicians to diagnose diseases based on mobile phone data, and even understand the careers of professors. Across many areas of biomedical research, his group analyzes large datasets to test new models and thus get closer to an understanding of complex problems in bioengineering, neuroscience, and beyond.
Dr. Kording’s appointment will be shared between the BE Department and the Department of Neuroscience in the Perelman School of Medicine.
In high school, Rebecca Kellner (right) always had a dual love of art and science. When she entered the University of Pennsylvania as a freshman, she thought that her interest in art would always be separate from her pursuit of science. “I’ve always loved art and science and I wondered how I would integrate my passions into one area of study,” Rebecca says. “Then I heard about the Network Visualization Program run by Dr. Danielle Bassett . In this program, the intersection of art and science is celebrated, and this intersection is a place where I feel right at home.”
The Penn Network Visualization Program, begun in 2014, had long been a dream of Dr. Bassett. She wanted a forum where young artists and research scientists could interact with each other. “Science and art are often perceived to be at odds with each other, two fundamentally different ways of understanding the world. As a scientist, I’ve learned that the visual impact of the information I present is crucially important. Networks are visually intuitive,” says Bassett, “and represent an opportunity to foster a common language between scientists and artists.”
In this six-week summer program, young artists spend time with scientists at Penn who are performing cutting-edge research in network science as applied to social systems, human biology, and physical materials, with the underlying goal of advancing bioengineering. Faculty from the Warren Center for Network and Data Science who have volunteered their time and creativity to the project include Eleni Katifori, Erol Akcay, and Randy Kamien of the School of Arts and Sciences; Robert Ghrist and Victor Preciado of the School of Engineering and Applied Sciences; Sandra Gonzalez-Bailon of the Annenberg School of Communications; and Francis Diebold of the Wharton School of Business. During the course of the internship, the artists produce works of art interpreting and capturing the intricacies of these networks in novel ways. Artistic supervision and project advice are provided by local artists affiliated with the program. The goal of the internship is to provide scientists with new conceptualizations of their research and to provide the intern with new knowledge in scientific art applications.
Rebecca was thrilled when she was accepted into the program. During her internship she worked with a variety of scientists. Her final artwork focused on the research of Dr. Ann Hermundstad (Janelia), the postdoctoral researcher in the Physics of Living Matter Group, University of Pennsylvania Department of Physics and Astronomy. Dr. Hermundstad’s research focuses on what and how the brain sees. Fascinated by these networks, Rebecca created a painting and a laser-etched acrylic book.
Nicholas Hanchak
The program also invites six high school students who have exhibited creativity and academic achievement. Nicholas Hanchak (right) from Westtown School participated during the summer of 2016. “I love art, science and baseball and I am thinking about architecture as a possible career,” Nicholas says. “The Penn program challenged me to find new ways to combine these interests.” For his final project, Nicholas created a Plinko Game Board showing the difference between the networks in a healthy brain and in a brain damaged by stroke.
“Artists and scientists are kindred spirits because they both are interested in observing what is in front of them,” says Dr. Bassett. “The Network Visualization program offers an opportunity for scientists and artists to inform each other in very tangible ways.”
The program runs every other summer. During the fall, several of the artists’ pieces are showcased in Philadelphia-area middle and high schools, particularly in disadvantaged areas. These efforts are enabled by ongoing collaborations with the Netter Center for Community Partnerships and Penn’s Center for Curiosity, and they are partially funded by the National Science Foundation. Bassett hopes this outreach effort will encourage children to explore intersections between the arts and sciences, while instilling a growing appreciation of their networked world.
Daniel K. Bogen,, MD, PhDDepartment chair David Meaney toasts Daniel Bogen
Daniel K. Bogen, MD, PhD, a professor in Penn’s Department of Bioengineering, is retiring. A Harvard alumnus (AB, 1972; PhD, 1977; MD, 1979). Dr. Bogen was the the first MD/PhD hired by the department in its history. Starting at Penn in 1982, Dr. Bogen spent his entire career on the faculty.
Early in his career, Dr. Bogen focused on cardiac tissue mechanics and understanding the functional changes that occur to heart tissue after ischemic insult. These publications were among the first to use finite element techniques to address the critical problem of how heart wall contraction changes after injury. Some of these papers are continually cited even today. Motivated to work on practical and applied clinical bioengineering-based problems, Dr. Bogen transformed his research to build items that patients would use. Rather than a timescale from discovery to application that can last decades for most academic researchers, Dr. Bogen’s new direction allowed him to put items in the hands of patients within months. In addition, Dr. Bogen’s led the PENNToys program, a nationally known program designing toys for children with disabilities.
The passion for impact also extended into the classroom. Reimagining the laboratory education in bioengineering, he used NSF-sponsored funding to create a discovery-based educational experience for undergraduates. This laboratory educational experience became an international model program, copied by many highly ranked bioengineering/biomedical engineering programs. This educational program was the cornerstone of the proposal funded by the Whitaker Foundation, leading to the construction of Skirkanich Hall, the current home of the Department of Bioengineering, in 2006. As a testament to his gifts as an education, Dr. Bogen’s teaching excellence was rewarded in 2005 with the Christian R. and Mary F. Lindback Award, which is the highest university teaching award bestowed by Penn.
Dr. Bogen will remain active in his retirement, and always enjoys hearing from alumni and students. Feel free to send him a congratulatory note — dan@seas.upenn.edu.
