Bio

I am currently pursuing PhD in Computer Science at University of Maryland, Baltimore County (UMBC). I am advised by Prof. Tejas Gokhale and I work on improving reliability and robustness in computer vision systems at the UMBC Cognitive Vision Group .

My current research focuses on two aspects of robustnes and reasoning in visual perception. I spend my time evaluating and improving computer vision systems to adapt to new domains, i.e. visual recognition module on Tesla developed and tested in sunny California should perform equally under change of domain, i.e. snowy Colorado. I investigate on leveraging LLMs and interpolation of images and latents in spectral domain to study domain generalization, domain adaptation, OOD detection, open-set recognition and, AI explainability.
