I am currently a postdoc in the Center for Data Science at New York University working with He He. My research interests are in AI safety and alignment. Specifically, I am interested in building a scientific understanding of where and why AI systems fail in order to inform the implementation of safety measures. Importantly, I believe AI has the potential to provide a great service to humanity, but on its current trajectory it has the potential to cause substantial harm.
I completed my PhD in Computer Science at University of Massachusetts Amherst working with Andrew McCallum on machine learning and natural language processing. During my PhD, I was generously supported by the NSF Graduate Research Fellowship and the Spaulding-Smith Fellowship.
