I am a Research Scientist in the Radiation and Cellular Oncology department of UChicago's Biological Sciences Division. My research focuses on developing automatic treatment planning 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.

Research

I am interested in applications of machine learning and mathematical optimization, particularly reinforcement learning and optimal control, in critical domains like healthcare. Some of my research efforts include developing closed-loop control solutions for neuromodulatory interventions, such as deep brain stimulation, and glycemic control systems for Type 1 Diabetes management.

Related projects include:
  • Closed-loop Control for Deep Brain Stimulation
    [Emory University '24]

    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.


  • Glycemic Control for Type 1 Diabetes Management
    [IBM Research '21 | Eli Lilly '23]

    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.


  • Reinforcement Learning for Sustainable Agriculture
    [IBM Research '22]

    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.


  • Fair Reinforcement Learning
    [IBM Research '21]

    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.


  • Reinforcement Learning and Graph Generation
    [Emory University]

    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.
