Research Scientist
Intel Labs

I received my PhD from the Department of Electrical Engineering at University of Southern California, under the advise of Prof. Hossein Hashemi. Currently, I work as a research scientist at Intel Labs, the research division of Intel Corporation.

I analyze and design integrated communication systems. Of particular interest to me are topics in quantization and synchronization. Application areas that I have worked on are fast hopping frequency synthesizers and interference tolerant receivers. Currently, I primarily work on cryogenic control for quantum computing.

From 2005 to 2009, I did undergraduate studies in the Department of Electronics and Electrical Communication Engineering at Indian Institute of Technology, Kharagpur. I am from Bengaluru.
