He earned doctoral and master’s degrees in physics from the University of Illinois Urbana-Champaign in 2012 and 2009, respectively, and a bachelor’s degree in physics and mathematics at Amherst College in 2006.
Heike Pfau, assistant professor of physics, studies materials with unique electronic properties, including those that can develop novel phenomena and unconventional electronic phases, such as superconductivity, heavy fermion behavior, nematicity, and quantum criticality. To better understand these phenomena, Pfau uses an imaging technique called angle-resolved photoemission spectroscopy as well as low-temperature transport and thermodynamic probes.
Pfau has published her research in journals such as Nature, Physical Review Letters, and Physical Review B. She was awarded a DFG Research Fellowship from the German Science Foundation in 2018, an Otto-Hahn Medal from the Max-Planck Society in 2016, a Springer Thesis Award in 2016, and a Feodor-Lynen Fellowship from the Alexander-von-Humboldt Foundation in 2015.

Ashley Villar, assistant professor of astronomy and astrophysics, uses a data-driven approach and machine learning to study the dramatic deaths of stars through collisions and explosions and how these events inform our understanding of the late stages of stellar evolution. She studies multimessenger astrophysics, primarily relying on broadband ultraviolet, optical, and infrared light curves, paired with analytical models, to understand the physical engines and astrophysical progenitors of extragalactic transients—astronomical events that last a short time.

Ruobo Zhou, assistant professor of chemistry, studies the clustering behaviors of proteins and RNA involved in fundamental cell functions. These behaviors, such as the sorting of proteins and RNA into nano- and micro-sized compartments to facilitate cellular function, are observed in a wide variety of biological processes, and dysregulation of these behaviors has been linked to cancer and neurodegenerative diseases. Using cutting-edge imaging techniques, such as super-resolution fluorescence microscopy and transcriptome-scale imaging, Zhou seeks to elucidate the origin, structure, and function of these clustering behaviors and understand how they respond to changing conditions during growth, development, and disease.
Zhou has published his research in journals such as Science, Nature, Nature Chemical Biology, Cell, and the Proceedings of the National Academy of Sciences. His previous honors include a Life Sciences Research Foundation Postdoctoral Fellowship, sponsored by the Howard Hughes Medical Institute, from 2014 to 2017 and a National Science Foundation Center for the Physics of Living Cells Fellowship in 2012.
Prior to joining the faculty at Penn State, Zhou was a postdoctoral fellow at Harvard University. He earned a doctoral degree in physics at the University of Illinois Urbana-Champaign in 2013 and a bachelor’s degree in applied physics at the University of Science and Technology of China in 2006.
