. His research centers on understanding material systems which exhibit coherent quantum effects at low temperatures, like superconductors and quantum magnetism. His principal scientific interest is understanding how is it that large ensembles of strongly interacting, but fundamentally simple particles like electrons in solids act collectively to exhibit complex emergent quantum phenomena. He exploits and develops techniques using low frequency microwave and THz range radiation that probe these systems at their natural frequency scales. The material systems of interest require new measurement techniques as their relevant frequencies typically fall between the range of usual optical and electronic methods.

He is known primarily for is work on superconductivity, magnetism, disordered systems, and topological materials. During his PhD., he did seminal work with angle resolved photoemission on the electron-doped cuprates. At Johns Hopkins, his group has measured the quantized magnetoelectric "
