I am a PhD candidate at Washington State University, advised by Prof. Jana Doppa.

I study how AI systems can make good decisions when trial and error is expensive or risky. My research spans safe reinforcement learning, where agents must maximize performance while keeping costs and risks within limits, and offline model-based optimization, where the goal is to discover better designs using only data from past experiments. This work is motivated by high-stakes applications such as materials discovery, healthcare, and smart grids.

Research

Safe Reinforcement Learning

Agents that maximize reward while satisfying safety constraints, whether they learn from logged data (offline) or through interaction (online).

  • Learning safe policies from fixed datasets
  • Adapting to safety requirements that change at deployment
  • Guarding against rare but severe failures

Offline Model-Based Optimization

Discovering high-performing designs from a fixed dataset of past experiments, when every new evaluation is costly.

  • Surrogate models that rank candidate designs reliably
  • Efficient search in high-dimensional design spaces
  • Applications to scientific discovery, such as new materials
