I am a (relatively new) assistant professor of Computer Science at Cornell University. I specialize in computer graphics, computer vision, human-computer interaction (HCI), as well as a random sampling of other topics.
The Before Times:
I completed my PhD at MIT in 2016, where I was advised by Fredo Durand, then worked as a postdoctoral researcher at Stanford University with Maneesh Agrawala until 2019, followed by a 1-year postdoc at Cornell Tech in NYC. I am now an assistant professor of computer science at Cornell University in Ithaca, NY.
Current office hours are by appointment for non-course related things. For CS4620 students, I generally schedule office hours so that they are shortly before assignment due dates; refer to the course website for the calendar.

I work on a range of topics in graphics, vision, and HCI, with most of my research focusing on how to apply work in these fields to new problems and application spaces. Below you will find a sampling of videos that describe different projects I've worked on. For a longer list of my publications, see my publications page or CV. My TED 2015 talk is also a good introduction to my work on visual vibration analysis.

Visual Rhythm & Beat Results
Abstract:We present a visual analogue for musical rhythm derived from an analysis of motion in video, and show that alignment of visual rhythm with its musical counterpart results in the appearance of dance. Central to our work is the concept of visual beats — patterns of motion that can be shifted in time to control visual rhythm. By warping visual beats into alignment with musical beats, we can create or manipulate the appearance of dance in video. Using this approach we demonstrate a variety of retargeting applications that control musical synchronization of audio and video: we can change what song performers are dancing to, warp irregular motion into alignment with music so that it appears to be dancing, or search collections of video for moments of accidentally dance-like motion that can be used to synthesize musical performances.
This example was a lot of fun to create. I found this Youtube channel for Dancing Nathan – a dog that does this strange flailing trick on a chair, which kind of looks like off-beat dancing.
