My story

In 2016 I obtained my PhD in computer science from Cornell University where I was advised by Noah Snavely and Kavita Bala. My research focused on building systems that analyze the massive numbers of photos found on the internet to better understand changes and trends that would be difficult to identify with the naked eye alone. This work touches on several areas of computer vision such as 3D reconstruction, object recognition, and used state-of-the-art machine learning techniques.

I grew up near a small town in Wisconsin and eventually went to the University of Michigan where I obtained BSEs in computer science engineering as well as computer engineering.

From 2016 to 2021 I worked on the Computational Photography team and, eventually, the XR Tech team at Facebook.
