- Crowdsourcing, reputation systems, open collaboration, the social web.
- Software design and analysis.
- Turning ideas into practice! Collaborating with startups and established companies in Silicon Valley and beyond.
- CrowdGrader, a system for crowdsourcing the grading of homework assignments. Students upload their submissions to homework assignments, and then review and grade each others' solutions. The system then computes consensus grades for the submissions, relying on a reputation system. You can:
- Reputation systems for collaboration.
- SlugIOT, a platform for the Internet of Things.
is a startup I co-founded that specializes in processing for webcam (and more!) images. Camio learns what you consider important and gives you intelligent alerts, and makes you whole video history searchable: "humans garden Tuesday" or "humans approaching door", or "car driveway" -- try it!
SimiCheck is a tool for detecting documents and homework similarity. SimiCheck understands code, text, Word (.docx), pdf, zip, tag, tgz, html, and more, and is able to compare code without being fooled by things like variable renaming and code moves.

Interested in UCSC?
is a great university where to study for an undergraduate or graduate degree. UCSC combines a wonderful campus, academically excellent degree programs, and a proximity to Silicon Valley that makes industrial collaborations, startups, exchange of ideas, and internships very easy. If you are considering UCSC for your undergraduate or graduate studies, you might want to check where my past collaborators are now
. The strongest testament to the excellence of a program are the careers of the people who were part of it!
