I'm a graduate student in the Caltech Vision Group under guidance of Professor Pietro Perona.
My research is mainly in visual recognition, focusing on the Visipedia Project.
Recently I have done some work on algorithms for estimating the expertise of annotators on Amazon Mechanical Turk.
Some of my research has gone into Anchovi Labs, a startup that offers an image annotation and analysis services for scientific and industrial applications
