I am working to develop a new area of computer science that I call Human Computation. In
particular, I build systems that combine the intelligence of humans and computers to solve large-scale
problems that neither can solve alone. An example of my work is reCAPTCHA, in which over 750 million
people-more than 10% of humanity-have helped digitize books and newspapers
