About Me

I am Rafid Ishrak Jahan, a Ph.D. student in the Department of Computer Science and Engineering at the University of North Texas, advised by Dr. Sagnik Ray Choudhury.

My research focuses on Large Language Model (LLM) evaluation, Natural Language Processing (NLP), Human Preference Learning, and Explainable AI (XAI). I am particularly interested in developing reliable evaluation methodologies, interpretable language models, and scalable benchmarks for modern AI systems.

Prior to beginning my Ph.D., I earned my M.S. in Computer Science (Thesis Track) from the University of North Texas and worked as a Technology Analyst at Infosys, where I developed enterprise-scale backend applications using Java, Spring Boot, Oracle Database, and Angular.
