About Me

Hi! I am a PhD student in the Halıcıoğlu Data Science Institute (HDSI) at UC San Diego, advised by Dr. Biwei Huang. I build scalable causal learning methods that help foundation models and agents learn structured world models—supporting robust generalization and long-horizon decision making.

My recent work spans causal learning from time series at scale, causality-guided world modeling for reinforcement learning generalization, and agentic systems for end-to-end causal analysis. Before joining UCSD, I worked with Dr. Konrad Kording on meta-learning methods on domain-specific causal discovery for large complex systems (e.g., microprocessors). I am also interested in brain-computer interfaces and computational neuroscience, and previously worked on real-time neurofeedback systems advised by Dr. Gan Huang.
