I am a Ph.D. student at the Bellini College of Artificial Intelligence, Cybersecurity, and Computing at the University of South Florida. I work as a Research Assistant under the supervision of Prof. Anshuman Chhabra in the PALM Lab. My research focuses on Generative Models (LLMs, VLMs), Agentic AI, Data-Centric AI, and Optimization. Previously, I have worked in the domains of Computer Vision and Automatic Speech Recognition.
Prior to starting my Ph.D., I worked as an NLP Engineer at Verbex AI, where I contributed to the development of Bengali Large Language Models and a multi-agent platform. I also served as a Machine Learning Engineer at ACI Limited, one of the largest conglomerates in Bangladesh, where I developed the ACI ChatBot and a Transformer-based Recommender System.
I believe that perseverance is essential to accomplishing any task. I strive to maintain this quality while being mindful of limitations. I organize my time efficiently to perform my responsibilities with focus and enthusiasm. I consider these qualities fundamental to skill development and achieving meaningful outcomes.
Outside of academics, I enjoy listening to music and aspire to travel the world to experience its natural beauty. In my leisure time, I also like to draw landscapes and natural scenery.
