I am a 4th year PhD candidate in the Department of Computational and Data Sciences (CDS) at the Indian Institute of Science, Bangalore with a research focus on Machine Learning and related areas. I am supervised by Prof. Partha Pratim Talukdar, and have been affiliated with the Machine And Language Learning Lab (MALL Lab) since August 2018.

Prior to graduate school, I received my Bachelor of Engineering (BE Hons.) in Computer Science from Birla Institute of Technology and Science, Pilani (BITS Pilani) in 2015.

I am currently looking for full-time positions (Research Scientist/Research Engineer/Post-doc) in Bangalore or remote, starting June 2022 or later.


I am broadly interested in machine learning, natural language processing and related fields. In my post-graduate work, I have had a specific focus on knowledge graphs (KG) and question answering. In this area, I have tried to improve QA performance by combining pre-trained language models with KG embeddings. I have also worked on making KG embeddings more scalable and easier to apply to downstream tasks. During my undergraduate studies I worked on humanoid robotics and computer vision.
