Haozhu Wang

I'm a Ph.D. student in EECS Department at University of Michigan, where I develop machine learning methods for scientific and healthcare applications. Previously, I received B.Eng. in Optoelectronics from a joint program at Tianjin University and Nankai University. I visited QNN lab at MIT RLE during my last year of undergraduate study.

I always enjoy collaborating with aspiring researchers. Please feel free to send me an email if you want to discuss about research ideas.

PS: I have many genius friends and this link will redirect you to one of them.

Research

I'm developing machine learning algorithms for healthcare and physical science applications. Specifically, I'm interested in reinforcement learning, meta-learning, domain adaptation, representation learning, and neuroscience.

There is nothing more practical than a good theory. — Kurt Lewin
