About

I started my PhD at MIT in 2018, working under Matt Evans. My work is mostly related to injecting and optimizing frequency depedent squeezing to achieve maximum broadband quantum noise suppression in LIGO. I graduated with a B.Tech in Physics from the Indian Institute of Technology in New Delhi which is also my hometown. I'm currently an LSC fellow at LIGO Hanford working on commissioning LIGO's quantum filter cavity for frequency dependent squeezing during O4. Outside of work, I like to spend time playing the piano, composing, producing and listening to music.
