JACQUELINE R. M. A. MAASCH

           

I am a fourth-year PhD candidate in computer science at Cornell Tech. I work at the intersection of machine learning and causal inference. My doctoral research has been supported by the NSF Graduate Research Fellowship, Cornell's Presidential Life Science Fellowship, and the Digital Life Initiative Doctoral Fellowship.

I am advised by Dr. Fei Wang, Dr. Volodymyr Kuleshov, and Dr. Kyra Gan. I am affiliated with the Weill Cornell Medicine Institute of AI for Digital Health. Formally, my concentrations are in artificial intelligence, scientific computing, and applied probability and statistics. Previously, I explored LLM reasoning as a research intern at Microsoft Research Cambridge.

I will be entering the job market in Fall 2025 / Spring 2026. If you are interested in collaborating, please reach out.

CURRENT WORK


My work centers on AI reasoning and the theory, methods, and applications of causal graphical modeling. I am motivated by urgent societal problems, including drug discovery and fairness in healthcare. Recent contributions include:
