JACQUELINE R. M. A. MAASCH

           



I am a fifth-year PhD candidate in computer science at Cornell Tech and the Weill Cornell Medicine Institute of AI for Digital Health. My doctoral research has been supported by the NSF Graduate Research Fellowship, Cornell's Presidential Life Science Fellowship, and the Digital Life Initiative. I am advised by Dr. Fei Wang, Dr. Volodymyr Kuleshov, and Dr. Kyra Gan. Previously, I was a research intern at Microsoft Research Cambridge.

I am interested in machine learning for reasoning and decision-making under uncertainty. This includes open problems in AI reasoning: building reasoning machines, what that requires in theory and practice, and its consequences for society. I approach these problems primarily through the theoretical frameworks of probabilistic and causal graphical modeling.
