PhD Student at University of Maryland, Baltimore County


Computer Vision | Machine Learning | Domain Generalization | Scene Understanding


I am currently pursuing PhD in Computer Science under the supervision of Dr. Tejas Gokhale at University of Maryland, Baltimore County (UMBC). Prior to that I was a Research Assistant at Center for Cognitive Skill Enhancement (CCSE) at Independent University Bangladesh (IUB). I have received a Masters of Science in Computer Science from University of Maryland, Baltimore County in May 2023 and a Bachelor of Science in Computer Science from BRAC University in August 2017.

My primary area of research is Computer Vision and Machine Learning. I am currently studying methods to impose strong shift invariance in CNNs, and mechanisms to circumvent class imbalance in semantic segmentation models. One of my other major area of interest is domain distribution shift for dense prediction (detection, segmentation, depth estimation) models, having methods that circumvent the lack of diversity in academically available datasets on which autonomous vehicle vision systems are trained is a cry for help! I am broadly interested in investigating attention based and knowledge infused vision models in the application of autonomous driving, and other sensory perception tasks. Another recent yet major research interest of mine is Vision + Language. I plan to explore mechanisms for infusing knowledge and visual grounding to build computer vision systems that are robust, efficacious and can interact with human in meaningful ways.
