My interest is in developing technologies for quantum and nano applications and my expertise is in optics, magnetics, and scanned probe microscopy. As an interdisciplinary faculty in Physics and Electrical, I focus on both fundamental as well as applied research.

Of particular interest are developing nanoscale magnetometers that rely on quantum sensors formed by defects in diamond with unique combination of optical and magnetic properties. Such magnetometers can have wide-ranging applications especially in nanoscale magnetic resonance imaging and spectroscopy. I am also working with collaborators in the institute for developing next generation of light sources such as single quantum emitters and microwave analog of laser (Maser). Some recent results are highlighted below.
