Dr. Guptasarma's research work spans interdisciplinary areas of physics, chemistry and materials science. The physics most interesting to Guptasarma and colleagues is often found near a critical phase transition bordering an unconventional quantum physical ground state. As a Condensed Matter Physicist and a Materials Scientist, Guptasarma seeks to elucidate the fundamental physics behind unusual electronic and magnetic properties of materials, ranging from large single crystals to tiny nanocrystals. The group’s work helps predict and discover new materials whose properties can have wide-ranging applications in present and futuristic electronic devices. Guptasarma currently directs the research of two postdoctoral scientists, four graduate students, and a number of undergraduate interns. His research is currently supported by federal (mostly NSF and DoD) and intramural research grants in the broad areas of novel superconductivity, magnetism and ferroelectricity. Other areas of investigation in Guptasarma's lab include research on new materials for batteries, photovoltaic devices, and multifunctional materials for device applications. Members of his research team come from a variety of backgrounds, including physics, chemistry, engineering, and surface science.
Dr. Guptasarma's research interests in the Scholarship of Teaching and Learning (SoTL) span topics of learner-centered teaching practice, discovery-driven learning, and the changing landscape of higher education.More information on his research can be found here.
Professor Prasenjit Guptasarma received a PhD in physics from the Tata Institute of Fundamental Research, after a Master's degree in physics at the Center for Advanced Research in Physics & Astrophysics, University of Delhi. He was a visiting professor and INFN fellow at the CNR Institute for Molecular Spectroscopy, and an NSF postdoctoral appointee at the Argonne National Laboratory. Dr. Guptasarma currently holds a tenured professorship with the department of Physics at the University of Wisconsin - Milwaukee (UWM), which he joined in the year 2000 as a assistant professor. Professor Guptasarma has published over 130 research articles and book chapters, and presented over 70 invited talks and lectures in different countries. He is an active member of several national and international collaborative research networks. He also serves on the editorial board of Advances in Condensed Matter Physics.
Recent recognitions of Guptasarma's research and teaching include UWM’s Research Fellow Award (2012) and Research Excellence Award (2008), the Research Growth Initiative award (2006 2011), the NSF Career Award (2005) from the US National Science Foundation, the Graduate School Research Committee award (2005), and the WSGC-NASA's Research Infrastructure award (2006). He was appointed Wisconsin Teaching Scholar in 2008. Dr. Guptasarma enjoys teaching at both undergraduate and graduate levels and has taught at every level from the 100s to the 800s at UWM.
Dr. Guptasarma is fluent in six languages, with a working knowledge of several others. In addition to interests in classical music, he composes and performs music in different musical genres within these ethno-linguistic styles.
