About Me

Turning Model Failures into Learning Opportunities

I'm a computer science graduate from Bangladesh University of Engineering and Technology (BUET) with a deep passion for understanding and improving AI systems. My research philosophy centers on the belief that the most valuable insights come from studying where and why models fail.


I am actively seeking PhD opportunities for Fall 2026 to advance research in vision-language AI systems, focusing on interpretability, efficiency, and real-world applications.
