Hi, I am Sankha! I am a first-year Computer Science PhD student at Georgia Institute of Technology, where I am advised by Prof. Vladimir Kolesnikov and Prof. Teodora Baluta. I am broadly interested in applied cryptography and machine learning security, particularly privacy-preserving ML auditing protocols.

Prior to GeorgiaTech, I was a pre-doctoral Research Fellow at Microsoft Research India (MSRI) in the cryptography group (called EzPC). At Microsoft, I was fortunate to be advised by Dr. Satya Lokam, Dr. Nishanth Chandran and Dr. Divya Gupta, under whose guidance I worked on cool problems in secure multi-party computation and differentially private machine learning.

I graduated with a Bachelor of Engineering (B.E.) in Computer Science from BITS Pilani, India in July 2023. In the past, I have interned at American Express and Goldman Sachs as a software developer. I was also a Google Summer of Code (GSoC) student (2021) and a mentor (2022).
