Soujanya Hazra

Kharagpur, WB, India.

Hello! This is Soujanya. I’m currently a second-year master’s student at Indian Institute of Technology, Kharagpur, enrolled in Signal Processing and Machine Learning, where I am advised by Dr. Sanjay Ghosh. Before joining IIT-KGP, I obtained my bachelor’s degree at Kalyani Government Engineering College, working with Dr. Pritam Kumar Gayen.

My research interest lies in:

Machine learning and explainability
EEG-based study of neurological disorders
Brain functional connectivity modelling
Medical image analysis for oral cancer
Representation learning using SSL

I’m open to research collaborations! If you’re interested in working together, feel free to reach out.
