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.

Opportunities for postdoctoral, graduate undergraduate researchers and visitors
We are always looking for motivated researchers with a background in condensed matter physics/materials science who may be interested in working with us. Current openings for postdoctoral researchers within my team are advertised on Argonne’s Career portal. Please contact me if you are interested in potential postdoctoral research opportunities in the future. 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.
