Machine Learning Researcher
me [@] jonathanpchen.com
I am a research scientist at Uber AI Labs in San Francisco, CA.
My area of interest is in statistical machine learning
and probabilistic programming, and their applications in cognitive science, vision, and language.
I seek to reverse-engineer the process in which humans reason about the world around them.
I coauthored the deep probabilistic programming language Pyro.
I also work on computer vision and perception in building maps for
I received my undergraduate degree in computer science from the University of Pennsylvania.
I've recently begun maintaining a research
