Zara Hall

Hi! I am a master’s student at Columbia University, where I study computer science.I am broadly interested in developing AI systems that are trustworthy and responsible. I am grateful to work with Kathy McKeown and Rich Zemel.

In the past, I completed my undergraduate degree at Columbia, where I was fortunate to work with Emily Black and Talia Gillis. Previously, I also worked on macro investing at Bridgewater and consulting at PwC.
