Boyu is an Assistant Professor in the Department of Computer Science at Western and an affiliated faculty member in the Vector Institute. He also holds adjunct positions in the Department of Statistical and Actuarial Sciences, the School of Biomedical Engineering, and the Brain and Mind Institute at Western. His research interests involve all aspects of machine learning: theory, algorithms, and applications. He received his Ph.D. in Computer Science from McGill University. Before joining Western in 2019, he was a postdoctoral fellow at the University of Pennsylvania and Princeton University.  

Research Interests

I am primarily working on transfer/multitask/lifelong learning, which is essential for building an intelligent agent in the real world with any amount of versatility. On the application side, I am interested in applying these techniques to brain signal analysis to solve the problems raised in neuroscience, biomedical engineering, neural engineering, healthcare, etc. I am also interested in applying these machine learning techniques to other real-world applications, such as smart grids and financial optimization.
