Wanyu is an Assistant Professor in the Department of Computing at The Hong Kong Polytechnic University. Wanyu is serving as an Associate Editor for  IEEE Transactions On Neural Networks and Learning Systems (TNNLS).

Wanyu’s main research interest is in the broad area of creating AI with safe and ethical objectives. Specifically, we focus on interpretability, fairness, robustness, and privacy-preservation of various kinds of machine learning models, including graph learning models and large pre-trained language models.
