About

Hello, I'm John Winder. I research artificial intelligence (AI) and machine learning for complex real-world systems. I lead the Advanced AI Algorithms section at the Johns Hopkins University Applied Physics Laboratory (JHU/APL). I also serve as a Faculty Member of the Data Science and AI Institute (DSAI) at JHU.

I received my Ph.D. in Computer Science from UMBC, where I specialized in reinforcement learning (RL). I focused on developing state abstractions for hierarchical RL and probabilistic planning. I had two excellent doctoral advisors, Marie desJardins and Cynthia Matuszek.

My main interest and objective is the creation of decision-making agents that generalize and reason about long-term goals under uncertainty, collaborating with humans and other AI agents, while operating in dynamic and open environments, facing new challenges in diverse scenarios.
