I am a final-year PhD candidate in the Department of Computer Science and Engineering at the University at Buffalo, SUNY, advised by Prof. A. Erdem Sarıyüce. Prior to my PhD, I earned a B.S. in Computer Science and Engineering from Shahjalal University of Science and Technology, Bangladesh in 2018. Additionally, I have 2+ years of software engineering experience at Samsung R&D Institute, Bangladesh.

My research interests are broadly in GraphRAG, Deep Learning, Natural Language Processing, and Graph Neural Networks. Currently, I am working on GraphRAG and hierarchical community detection for question answering, aiming to improve query-focused summarization with LLMs and Generative AI.
