We seek to discover and understand novel electronic and magnetic properties that emerge in epitaxial thin films and heterostructures of various crystalline materials. My group works 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.
Our 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.
Fellow of the American Physical Society (elected 2019).

Opportunities for postdoctoral, graduate, undergraduate researchers and visitors
We are always looking for motivated researchers with a background in condensed matter physics/materials science/electrical engineering who may be interested in working with us. As of June 2022, we have a postdoctoral opening in the area of topological semimetals. I am also keen to sponsor applicants for the Maria Goeppert Mayer Fellowship at Argonne.
We support graduate students towards their doctoral dissertation. I am affiliated with UChicago CASE and will advise Ph.D. students at the Pritzger School of Molecular Engineering (PME), University of Chicago. If you are a current or prospective graduate student at PME and are interested in our area of research, please do get in touch. Students from other universities are also welcome, through suitable arrangements made with faculty at their home institution. Please take a look at the various ways that graduate students can work with us, and contact me if you wish to learn more.
