About Me:

Hello! I am an AI Research Scientist at Salesforce Research. My current research focuses on building state of the art generative models for Computer Vision and NLP. I am currently interested in the following broad research directions:

  • Improving the quality and controllability of image generation models
  • Adaptation of LLMs using real and synthetic feedback data
  • Developing an interface between visual data and language through multi-modal LLMs

Before joining Salesforce, I received a PhD from Carnegie Mellon University working with Prof. Abhinav Gupta. In the past, I have worked on a very diverse range of topics in Computer Vision, Robotics and NLP. Check out my papers below and reach out to me if you would like to chat!
