Chen Ma is a PhD student in the School of Computer Science at McGill University, supervised by Prof. Xue (Steve) Liu. His research is on the intersection of recommender systems and deep learning, especially on learning effective representations of users, items, and user-item interactions in recommender systems. The central theme driving his research work is to search for effective auxiliary information, powerful models, adaptive/personalized hyper-parameters, and fairness-aware recommendation results.
He is also a core developer of a Java opensource library on recommender systems–LibRec.
