M.Sc. Physics (Int.), Indian Institute of Technology, Kanpur, India

Ph.D., Physics, University of Minnesota

We seek to discover and understand novel electronic and magnetic properties that emerge in epitaxial thin films and heterostructures of various crystalline materials. We work with correlated complex oxides, and more recently also with topological semimetals.  We synthesize our samples using molecular beam epitaxy and study them using a broad range of techniques that probe their charge and spin transport properties and their magnetic and electronic structure. 

My research is supported by the US Department of Energy, Office of Science, Basic Energy Sciences. We are also part of the Center for Advancement of Topological Semimetals (Energy Frontier Research Center), and the Center for Predictive Simulation of Functional Materials.
