The INFORMS 2020 was fully online (was to be held in D.C.). I served as a panelist at INFORMS New Faculty Colloquium. Our research group made the following three presentations.

• Optimal Control of Remanufacturing with Parameter Uncertainty, by Zhicheng Zhu, and Yisha Xiang
• Predictive Maintenance Management with Prognostics Information Based on Higher Order Hidden Semi-Markov Models, by Ying Liao, and Yisha Xiang
• Condition-based maintenance for deteriorating systems subject to ambiguity in transition probabilities, by Yue Shi, and Yisha Xiang
