Research

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. Dr. 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.
