I am an Assistant Professor of Computer Science at Brandeis University. My research interests center around machine learning, data mining, and their applications. Recently, I focus on developing effective, efficient, and trustworthy machine learning models and algorithms, particularly on network/graph and multi-modal data. I also develop artificial intelligence techniques for public health, illicit activity combatting, social/information network analysis, recommender systems, and interdisciplinary problems. Before Brandeis, I did my PhD study at Notre Dame, advised by Nitesh Chawla.
