About Me

I am a computer scientist specializing in computer vision, computer graphics, computational photography and human-computer interaction. I completed my PhD at MIT in 2016, where I was advised by Fredo Durand, and am now a postdoctoral researcher at Stanford University working with Maneesh Agrawala.

I'm interested in a lot of topics, but most of my research has something to do with using images in new and interesting ways. Click on the Research tab to find out more.

I did my undergraduate at Stanford, where I worked with Marc Levoy on graphics and computational photography.

I'm from Baltimore City, and am a proud graduate of the Baltimore Ingenuity Project, which you can learn more about in the Other tab.

I dabble in lots of different art -- as a hobby and, recently, as inspiration for research projects (e.g., video editing, photography, special effects).
One of my more consistent hobbies is music. Most of what I put on line is math- and science-themed rap. For more on that, click the Music tab.

Computational Video Editing:


This past summer Mackenzie Leake presented our SIGGRAPH 2017 paper on computational video editing. This project was a ton of fun, and features the acting talents of Pointless Theater, a DC theater company.

Update: We won the SHM in Action Award at IWSHM 2017!

Our work on Computational Bounce Flash was published at SIGGRAPH Asia 2016:

We created a robotic bounce flash that automatically searches for good bounce surfaces and reorients itself so the photographer can stay focused on getting the best shot. Check it out!

My TED 2015 talk

I was honored to be a speaker at TED 2015. My research has since progressed, but this talk remains a pretty good introduction to my dissertation work.

An extended version of our CVPR 2015 paper on Visual Vibrometry has been published in PAMI 2016:

This work explores how material properties like density, stiffness, and damping, can be recovered from analysis of vibrations in video.

We presented our TOG paper on light fields at SIGGRAPH 2015.

I am honored to be one of Business Insider's '8 most innovative scientists in tech and engineering' for 2015.

(10/31/2015) I am in Japan presenting our SIGGRAPH Asia 2015 paper. More info and a video to follow!

We have papers at NDT-CE and IWSHM 2015 in collaboration with folks from MIT's Civil Engineering Department!
