I am a research scientist at Adobe Research, Bangalore with a research focus on NLP and multi-modal machine learning.
Previously I was a PhD candidate in the Department of Computational and Data Sciences (CDS) at the Indian Institute of Science, Bangalore. I was supervised by Prof. Partha Pratim Talukdar.
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.
Research
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.
