I am a Research Scientist in the department of Radiation & Cellular Oncology at the University of Chicago, working with Dr. Zhen Tian on developing automatic treatment algorithms for various radiotherapy modalities.
I obtained my PhD in Computer Science from Emory University where I was advised by Dr. Lars Ruthotto, and supported by a Google PhD Fellowship in Computational Neural and Cognitive Sciences. Prior to Emory, I studied Computer Science/Information Systems and Mathematics at The College of Saint Scholastica.
My research focuses on machine learning and mathematical optimization, particularly reinforcement learning and optimal control in critical domains like healthcare. I develop closed-loop control solutions for neuromodulatory interventions, such as deep brain stimulation, and glycemic control systems for Type 1 Diabetes management.
Some representative projects include:Interdisciplinary collaboration with Dr. Lars Ruthotto and Dr. Nicholas Au Yong on developing adaptive control algorithms for optimizing deep brain stimulation via Reinforcement Learning and Optimal Control.
Implemented various control strategies for managing blood glucose levels in simulated Type 1 Diabetes patients. Leveraged RL and OC theory to model the glucoregulatory system and develop algorithms for real-time insulin delivery, reducing the risk of hyperglycemia and hypoglycemia across various meal scenarios.
Developed SWATGym, a reinforcement learning environment for crop management based on the Texas A&M Soil & Water Assessment Tool(SWAT). SWATgym enables evaluation of various crop management strategies on a full growing season. It includes standard and RL-based agents for decision-making, and a reward function that captures the trade-offs between crop yield and environmental impact.
Exploring bias in patient representation in healthcare and developing a fair treatment strategy by leveraging representation learning and reinforcement learning. Work done during internship with IBM Research in collaboration with the talented team at the Center for Computational Health: Mohamed Ghalwash, Zach Shahn, and Pablo Meyer Rojas.
Applying model-based Reinforcement Learning strategies in the field of graph generation, in particular, to generative models that can learn to create novel graphs efficiently.
