Kartik received his BS, MS and PhD degrees in applied physics from the California Institute of Technology, where his graduate research was supported by a Fannie and John Hertz Foundation Fellowship. He worked for a year at XPonent Photonics, a startup company based in Monrovia, California. After completing his PhD, he continued at Caltech as a postdoctoral fellow at the Center for the Physics of Information. In September 2007 he joined the CNST, where he is leading projects in the field of nanophotonics, a branch of optical engineering dealing with the study of the behavior of light on the nanometer scale.
Kartik has published over 40 peer-reviewed papers in journals like Nature, on topics including microcavity lasers, chip-based cavity quantum electrodynamics, near- field optical probing, semiconductor quantum dots, and the electromagnetic design and nanofabrication of photonic crystal devices.His parents, Vilappakkam Srinivasan and Kalpagam Srinivasan, both hail from Chennai and immigrated to the US in 1971.
Kartik is the project leader of the Research Group on Nanofabrication at the Center for Nanoscale Science and Technology, which is part of the Gaithersburg, Maryland-headquartered National Institutes of Standards and Technology under the purview of the Department of Commerce.
