Previously I was a Human Computer Interaction researcher. I spent some time as a Visiting Scholar at the CS Department of Carnegie Mellon University, working with Professor Luis von Ahn in the field of Human Computation. More recently, I was part of Professor Bjoern Hartmann's lab at Berkeley. In between I spent four years at Endeca as a Senior Software Engineer.
My work has been covered by The New Yorker, The Wall Street Journal, and the Washington Post among many others. It was exhibited at the Israeli Design Museum and is part of the permanent collection of the Deutsches Museum.
I am a recipient of the U.S. National Science Foundation Graduate Research Fellowship, the California Legislature Grant for graduate studies, the Samuel Silver Memorial Scholarship Award for combining intellectual achievement in science and engineering with serious humanistic and cultural interests and Rising Stars in EECS.
Audio to motion translation.
Human speech is often accompanied by hand and arm gestures. Given audio speech input, we generate plausible gestures to go along with the sound. Specifically, we perform cross-modal translation from ``in-the-wild'' monologue speech of a single speaker to their hand and arm motion. We train on unlabeled videos for which we only have noisy pseudo ground truth from an automatic pose detection system. We release a large video dataset of person-specific gestures.
"Do as I do" motion transfer.
Given a source video of a person dancing we can transfer that performance to a novel (amateur) target after only a few minutes of the target subject performing standard moves. We pose this problem as a per-frame image-to-image translation with spatio-temporal smoothing. Using pose detections as an intermediate representation between source and target, we learn a mapping from pose images to a target subject's appearance. We adapt this setup for temporally coherent video generation including realistic face synthesis.

"What makes the 60's look like the 60's?"
Many details about our world are not captured in written records because they are too mundane or too abstract to describe in words. Fortunately, since the invention of the camera, an ever-increasing number of photographs capture much of this otherwise lost information. This plethora of artifacts documenting our “visual culture” is a treasure trove of knowledge as yet untapped by historians. We present a dataset of 37,921 frontal-facing American high school yearbook photos that allow us to use computation to glimpse into the historical visual record too voluminous to be evaluated manually. The collected portraits provide a constant visual frame of reference with varying content. We can therefore use them to consider issues such as a decade’s defining style elements, or trends in fashion and social norms over time.

The human visual system is just as good at recognizing objects in paintings and other abstract depictions as it is recognizing objects in their natural form. Computer vision methods can also recognize objects outside of natural images, however their model of the visual world may not always align with the human one. If the goal of computer vision is to mimic the human visual system, then we must strive to align detection models with the human one. We propose to use Picasso's Cubist paintings to test whether detection methods mimic the human invariance to object fragmentation and part re-organization. We find that while humans significantly outperform current methods, human perception and part-based object models exhibit a similarly graceful degradation as abstraction increases, further corroborating the theory of part-based object representation in the brain.

Speech input is growing in importance, especially in mobile applications, but less research has been done on speech input for information intensive tasks like document editing and coding. This paper presents results of a study on the use of a modern publicly available speech recognition system on document coding.

A tablet-controlled, solar-powered drip irrigation system. A humidity sensor at the tip of each "spike" records soil moisture; an internal servo in the 3D-printed enclosure opens and closes a drip irrigation line valve. Individual devices in a garden communicate with a central garden server, which also acts as a webserver that hosts the HTML-based user interface. Gardeners can review graphs of humidity readings over time and adjust waterning plans through this Web application.
