Bio
I am a Computer Science PhD student, working under the guidance of
Tejas Gokhale
in the UMBC Cognitive Vision Group
at University of Maryland, Baltimore County (UMBC).
I work on interactive multimodal retrieval/search, multimodal reasoning, and video understanding.
My research spans the following areas:
♦ Interactive Multimodal Retrieval, Search: Enhancing few-shot and zero-shot video search and retrieval, Developing Scene Graph-based Chain-of-Thought retrieval frameworks, Designing dialogue-driven interactive retrieval systems, Robust Ranking Evaluation.
♦ Video Understanding: Information Theory guided Video Question Answering (VQA), Progressive Video Captioning, Semantic Frame Selection, Video Editing.
♦ Visual Reasoning: Understanding spatial relationships and transformations, Studying counterfactual visual reasoning, Exploring techniques for image and model editing.
