About Me
Basics:
I am an 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 by appointment. Including "?Office Hours?" in the title of your email might help me see it.

Update: Fall 2023 (SIGGRAPH, ICCV, CHI, UIST, etc…)
I clearly don’t update this website as much as I should. I have added new papers to the Publications tab. I will try to launch a group website as soon as I can to better feature the students who are working on these projects. Stay tuned.
Update SIGGRAPH 2021: A Mathematical Foundation for Foundation Paper Pieceable Quilts
Our work on the geometry of paper piecing quilt designs, with first author Mackenzie Leake was published at SIGGRAPH 2021!
Update CVPR 2020 Oral: Visual Chirality Nominated for Best Paper at CVPR2020
Our work on Visual Chirality, with Zhiqiu Lin, Jin Sun, and Noah Snavely is an oral at CVPR, and one of the nominees for best paper! Check out the webpage and video to learn more about the work.
Update ECCV 2020 Oral: Crowdsampling the Plenoptic Function
Our work on crowdsampling the plenoptic function was selected for ECCV Oral! Learn from Internet photos to create interactive space-time views of popular attractions! With self-supervision!
Work with Zhengqi Li, Wenqi Xian, Noah Snavely. Check out the webpage and video to learn more.
Select Research Highlight Videos
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
[Project Page]
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.

Spot The Dancing Robot
Remix of Spot The Dancing Robot from Boston Dynamics.
Psy's Best Friend
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.
Kitty Shake Shake It
Cats dancing. Enough Said.
