Vatsal Agarwal

I am a second year Ph.D student in the department of Computer Science at the University of Maryland (UMD), advised by Professor Abhinav Shrivastava. My research lies at the intersection of computer vision and deep learning.

I completed my undergrad in Computer Science at the University of Maryland in 2022. During my undergrad, I worked as a research assistant at the National Institutes of Health Clinical Center to develop deep learning models for medical imaging. I also interned as a machine learning engineer at DeepHealth.

In the past, I have been fortunate to have worked with Youbao Tang, Bill Lotter, Ronald Summers, Suhas Srinivasan.

Research

I am interested in developing computer vision models that are able to leverage multimodal knowledge from vision-language models for scene understanding tasks such as open-vocabulary segmentation. I am also broadly interested in developing efficient attention methods that scale across various applications including image classification and human mesh recovery.
