I am a PhD student at the CS Department of the University of California Berkeley working with Alyosha Efros.

Previously I was 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 spent four years at Endeca as a Senior Software Engineer.

My research is supported by the U.S. National Science Foundation Graduate Research Fellowship and by a California Legislature Grant for graduate studies.


  • object detection in a Picasso image

    Object Detection in Abstract Art

    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 interface for document coding

    Using Speech Recognition in Information Intensive Tasks

    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.

  • multi-stage code examples editor

    Editable Code Histories

    An IDE extension that helps with the task of authoring multi-stage code examples by allowing the author to propagate changes (insertions, deletions and modifications) throughout multiple saved stages of their code.

    Phetch - A Human Computation Game

    Phetch is an online game which collects natural language descriptions for images on the web as a side effect of game play. Can be used to improve the accessibility of the web as well as improve upon current image search engines.

  • H20-IQ device


    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.

    Joint class project with Valkyrie Savage and Mark Fuge.
