Dennis E. Discher, Ph.D. 

Robert D. Bent Professor, and Director, Physical Sciences Oncology Center/Project

University of Pennsylvania, Philadelphia, PA

Biography: The Discher lab has sought to identify and elucidate some soft matter concepts across cell, molecular and tissue biology. They also have, occasionally, used biological approaches to inject some biological insights into soft matter science and engineering. Early discoveries included matrix elasticity effects on stem cell maturation and differentiation (Cell 2006), mechanosensing by a cell’s nucleus (Science 2013), and properties scaling of amphiphilic polymer assemblies for nano-delivery (Science 2002).  Current efforts focus on physics-driven evolution of mutations (Cell 2016) and engineering of macrophages to attack solid tumors (Nat BME 2023). The latter followed molecularly detailed studies of ‘foreign’ versus ‘self’ recognition (Science 2013). Dozens of trainees have secured positions in academia or industry around the world. Discher has been elected to the US National Academy of Medicine, the US National Academy of Engineering, and the American Association for the Advancement of Science, and he serves on Editorial Boards of Science, Molecular Biology of the Cell, and PNAS Nexus among other journals.

Andrew Stephens, Ph.D.

Assistant Professor, Department of Biology

University of Massachusetts Amherst

Biography: Prof. Andrew Stephens was born and raised in Kansas City, Missouri. He received his undergraduate degree from the University of Missouri, Kansas City and studied dynein processivity in single molecule assays. Stephens completed his Ph.D. at the University of North Carolina Chapel Hill in Dr. Kerry Bloom's lab where he studied the pericentromeric chromatin spring's essential role in yeast mitosis. He continued as a Post Doc in Dr. John Marko's lab at the University of Northwestern to adapt micromanipulation force measurements to single nuclei and study the importance of chromatin mechanics in controlling abnormal nuclear morphology which is present in many human diseases. He is now an Assistant Professor at the University of Massachusetts Amherst. The Stephens Lab was started in 2020 and uses a combination of nuclear force measurements and cell biology to determine the mechanical force balance between the nucleus and the cytoskeleton which controls nuclear shape, integrity, and function.  

John F. Marko, Ph.D.

Departments of Physics & Astronomy and Molecular Biosciences

Northwestern University

Biography: John Marko is a professor of Physics & Astronomy and Molecular Biosciences at Northwestern University in Evanston, Illinois. He graduated from the University of Alberta, Edmonton with a B.Sc. in physics in 1984, then received his Ph.D. in physics from Massachusetts Institute of Technology in 1989. Prof. Marko’s research interests include biological physics, statistical mechanics and theoretical soft matter physics applied to problems of self-organization in molecular and cell biology.

The Marko lab uses biophysical methods, with particular emphasis on micromanipulation of single DNA molecules and single chromosomes, to study the internal structure of chromosomes in vivo, and to study chromosome-organizing proteins and DNA topoisomerases in vitro. They also develop mathematical models relevant to these types of experiments. Projects in progress involve combining fluorescence microscopy and force microscopy in experiments on DNA-protein complexes and whole chromosomes, and in-vivo studies of coupling of chromosome dynamics to gene expression.

Biography: Gary Brudvig is the Benjamin Silliman Professor of Chemistry, Professor of Molecular Biophysics & Biochemistry, and Director of the Yale Energy Sciences Institute at Yale University.  He received his B.S. (1976) from the University of Minnesota, his Ph.D. (1981) from Caltech and was a Miller Postdoctoral Fellow at the University of California, Berkeley from 1980 to 1982.  Professor Brudvig has been on the faculty at Yale since 1982. Brudvig served as Chair of the Chemistry Department from 2003-2009 and 2015-2018.  Since 2012, Brudvig has been the Director of the Energy Sciences Institute located at Yale’s West Campus where he oversees the development of new research programs and facilities related to renewable energy, alternative fuels, and materials science.  His research involves study of the chemistry of solar energy conversion in photosynthesis and work to develop artificial bioinspired systems for solar fuel production.

Dr. Wolfgang Nitschke

Research Director, Bioenergetics and protein engineering laboratory (BIP)/CNRS

Prof. Nitschke has been studying bioenergetics all his academic life, beginning with a Ph. D. on photosynthetic electron transfer in plants at the University of Regensburg in Germany and, after drifting towards prokaryotic photosynthesis during 5 years as post-doctoral fellow in Paris, serving as a professor in Freiburg Germany. Upon moving to Marseille, France, he addressed electron transport and the implied energetics in an expanding repertoire of biochemical processes and bacterial species. He led the “Evolution of Bioenergetics" research group from 1995 until his retirement in 2023 and was vice-director of the department “Bioenergetics and Protein Engineering” from 2002 to 2006. Through a career dedicated to biological energy conversion, he was convinced of the fundamental importance of energy to life (and beyond). His professional bio reports that since his retirement he is 'able to finally do research without the crazy administrative workload'.

Dr. Elizabeth Hillman

Columbia University

Elizabeth Hillman is professor of biomedical engineering and radiology at Columbia University and a member of the Mortimer B. Zuckerman Mind Brain Behavior Institute and Kavli Institute for Brain Science at Columbia. Hillman received her undergraduate degree in physics and Ph.D. in medical physics and bioengineering at University College London and completed post-doctoral training at Massachusetts General Hospital/Harvard Medical School. In 2006, Hillman moved to Columbia University, founding the Laboratory for Functional Optical Imaging. Hillman’s research program focuses on the development and application of optical imaging and microscopy technologies to capture functional dynamics in the living brain. Most recently, she developed swept confocally aligned planar excitation (SCAPE) microscopy, a technique capable of very high speed volumetric imaging of neural activity in behaving organisms such as adult and larval Drosophila, zebrafish, C. elegans and the rodent brain. Hillman’s research program also includes exploring the interrelation between neural activity and blood flow in the brain, as the basis for signals detected by functional magnetic resonance imaging (fMRI). Hillman is a fellow of the Optical Society of America (OSA), the society of photo-optical instrumentation (SPIE) and the American Institute for Medical and Biological Engineering (AIMBE).
