Sagar Deep Deb
I am currently working as an Institute Post-Doctoral Fellow at the Department of Bioscience and Bioengineering, Indian Institute of Technology Bombay, and advised by Prof Deepak Agrawal and is working to understand Ventilator Dyssynchrony, its occurrence, and detection. I am interested in solving healthcare-related projects using machine learning and deep learning techniques. I completed my PhD in the year 2024, and the title of my thesis was "Pectoral Muscle Segmentation, Breast Cancer Classification and Multimodal Data for Prognosis Prediction using Deep Learning Models."
