I'm a Ph.D. candidate in the Computer Engineering and Systems Laboratory with Prof. Seda Ogrenci-Memik at Northwestern University in Evanston Illinois, USA.

My research till now has focused on associative memory design and testing, and in the fabrication and integration of thin-film thermocouples in 3D ICs for temperature measurement and thermal management. We are working with Dr. Ted Liu and Dr. James Hoff at Fermi National Accelerator Laboratory on a Vertically Integrated Pattern Recognition Associative Memory (VIPRAM) for fast-track finding at the LHC. I have been involved in the complete cycle - from design to testing of a pattern recognition associative memory chip fabricated in 130nm lp CMOS.

I attended B.I.T.S. Pilani in Pilani for my undergraduate. I worked at Intel in Hillsboro, Oregon U.S.A. in Dr. Chandramouli Kashyap's group with Dr. Chirayu Amin in Spring+Summer of 2016; and again in Summer 2018. I have also worked at Fermi National Accelerator Laboratory, Batavia Illinois and C.E.R.N, Geneva Switzerland as a visiting researcher and summer student. I enjoy cricket, squash, video games and classic rock.
