I mostly work on (i) accessibility (esp. access technologies), (ii) crowdsourcing and human computation (esp. systems that combine AI and human intelligence together, and work to improve the worker experience), and (iii) dialog systems (esp. those that deeply integrate human computation and dialog together).
