Researcher in HCI - CSCW - Social computing I am currently a research scientist at FXPAL. I work on understanding how technology designed to support remote collaboration can facilitate social interaction, information sharing, and telepresence. I received a PhD from Carnegie Mellon University's Human-Computer Interaction Institute, where my dissertation focused on the social dynamics of impression formation in online peer production for expertise assessment, learning, and professional development. I am also interested in designing technology to support sharing, collaboration, and awareness across time, geographic distance, and language boundaries. I have explored these topics in the context of projects including work conducted with Google, Microsoft Research, and Tate Online.
