Hi there! I’m a Research Scientist at Fujitsu Research, where I focus on developing quantum algorithms for efficient simulation of open quantum systems.

Before this, I was fortunate to spend time at Microsoft Research, where I worked with Nishanth Chandran on applying cryptography to enable secure inference for Large Language Models.

I completed my Master’s at IIIT Hyderabad, where I explored quantum algorithms for intermediate-term quantum devices, advised by Shantanav Chakraborty and Subhadip Mitra. You can read my thesis here.
