Research interest: Machine Learning, Brain Imaging, Computational Neuroscience, AI for healthcare.

My research involves the areas of machine learning, optimization, signal processing, and control theory with applications to the healthcare and renewable energy field. I am particularly interested in using machine learning and data analytics to understand the brain mechanism and provide solutions for brain disorders.

Currently, our group has two projects 1) brain source imaging utilizing graph structures in the data. 2) deep learning framework for melanoma recurrence prediction based on H&E whole slide images.
