Biography
I'm a research scientist in the Intelligent Systems Lab at Intel, where I work with Vladlen Koltun. I'm interested in using photorealistic synthetic data for computer vision. Previously, I was a research scientist at Apple, where I led the development of the Hypersim dataset.
In 2019, I received my PhD from Stanford University, where I was advised by Pat Hanrahan. My dissertation work was at the intersection of computer graphics, robotics, and computer vision, where I focused on enabling drones to scan 3D environments and execute cinematic camera trajectories. During my graduate studies, I interned at Microsoft Research and Skydio. Before attending Stanford, I was a research fellow at Harvard University, where I was advised by Hanspeter Pfister. In 2012, I worked with John Owens and David Luebke to develop the Introduction to Parallel Programming course at Udacity. In 2009, I interned at NVIDIA.
For an overview of my dissertation work, see this talk from TEDxBerkeley 2017.

Hypersim: A Photorealistic Synthetic Dataset for Holistic Indoor Scene Understanding
|
For many fundamental scene understanding tasks, it is difficult or impossible to obtain per-pixel ground truth labels from real images. We address this challenge by introducing Hypersim, a photorealistic synthetic dataset for holistic indoor scene understanding. To create our dataset, we leverage a large repository of synthetic scenes created by professional artists, and we generate 77,400 images of 461 indoor scenes with detailed per-pixel labels and corresponding ground truth geometry. Our dataset: (1) relies exclusively on publicly available 3D assets; (2) includes complete scene geometry, material information, and lighting information for every scene; (3) includes dense per-pixel semantic instance segmentations and complete camera information for every image; and (4) factors every image into diffuse reflectance, diffuse illumination, and a non-diffuse residual term that captures view-dependent lighting effects.
Software
Flashlight: A Python Library for Analyzing and Solving Quadrotor Control Problems

Flashlight is a lightweight Python library for analyzing and solving quadrotor control problems. Flashlight enables you to easily solve for minimum snap trajectories that go through a sequence of waypoints, compute the required control forces along trajectories, execute the trajectories in a physics simulator, and visualize the simulation results. Flashlight also makes it easy to simulate external disturbances, and to recover from those disturbances using time-varying LQR feedback control. Flashlight includes physical models for 2D quadrotors, 3D quadrotors, and 3D quadrotor cameras.
Personal
Before going to Stanford, I used to DJ in front of hundreds of people every weekend. I was a resident at The Republik and The Bamboo Tiki Room in Calgary, Canada. The Republik and the Bamboo were voted the 2nd and 3rd best places to dance in the FFWD Best of Calgary 2010. More recently, I won a national DJing competition to perform at Glowchella 2013 in San Francisco, and I have subsequently opened for The Chainsmokers, Martin Solveig, and several other notable international artists.
I think of my sound as a funky chunky soul stomp bigbeat boogaloo mashup of timeless dance music, i.e., imagine what it would sound like if James Brown, Ray Charles, The Beatles, Fatboy Slim, and Daft Punk all took acid together and played a sweaty warehouse primetime party set at the Apollo Theater Harlem NYC circa 1969. You can listen to a mix here. Note that Boogaloo is a genre of Latin dance music from the 1960s.
