I am a PhD student in systems & networking at Cornell University, where I work with Hakim Weatherspoon. I am primarily interested in networking problems. I also work with Sylvia Ratnasamy and the Google Systems Research Group on Traffic Engineering for SDNs.

Previously, I was at Microsoft Research India, working with Muthian Sivathanu and Ram Ramjee. Here, I worked on distributed systems to support training for large language models like GPT and BERT.

Before that, I worked at Microsoft’s engineering division for a year and graduated from IIIT Delhi.
