I am currently a post-doc at Stanford working for John C. Duchi and Percy Liang on tradeoffs between the average and worst-case performance of machine learning models. Machine learning systems do well on their training domain, but often fail in dramatic and unexpected ways in the wild. I view these problems as coverage issues - systems can appear to do well even if they fail on rare examples (in prediction) or plagiarize from the training set (in generation). My work seeks to develop evaluations, representations, and training procedures to guarantee uniform, rather than just average performance of machine learning models.
Before this, I was a graduate student at MIT co-advised by Tommi Jaakkola and David Gifford, and a undergraduate student at Harvard in statistics and math advised by Edoardo Airoldi.
