Markets for Information Exchange

Can Markets Help?

Work with Scott Hudson, Robert Kraut and Roberto Weber at Carnegie Mellon University. This project explores how market mechanisms can be used to improve information exchange. What are important factors that need to be considered when designing a marketplace for information?

Real-Time Question and Answer (Q&A) Markets

Work with Scott Counts at Microsoft Research. We built a real-time Q&A system and explored how monetary incentives impacted question asking and answering behavior.

Mediation of Communication

Factors Influencing Communication Decision

Work with Laura Dabbish, Robert Kraut and Scott Hudson at Carnegie Mellon University. The goal of the project is to understand response beahvior. How does one's decision and knowledge about communication urgency/importance and who the sender is influence one's response decisions?

Tagging of Instant Messaging

Work with Jennifer Lai at IBM T.J. Watson Research Center. The goal of the project is to improve near-synchronous communication by allowing senders to indicate communication intent and by providing automated communication support to receivers.

Privacy Support for Information Disclosure

Work with Karen Tang and Jason Hong at Carnegie Mellon University. The goal of the project is to explore the privacy support for information disclosure. We explored the design of feedback and control mechanisms in our IM BOT information disclosure service IMBuddy.

Interactive Displays

Peripheral Display of Handwritten Notes

Work with Ken Wood at Microsoft Research Cambridge, Cambridge U.K., working in the Computer-Mediated Living Group. The goal of the project is to present personal, digital notes in a way that supports serrendipidous rediscovery.

EyeCanvas

Work with Elizabeth Churchill at Fuji-Xerox Palo Alto Research Center. The goal of the project is to explore the transfer of information through a walk-up interactive display in Cafe located in San Francisco.

Evaluating Peripheral Displays

Work with Jennifer Mankoff and Anind Dey at UC Berkeley. The goal of the porject is to explore evaluation techniques and metrics for ambient/peripheral displays.

Interactive Environments for the Elders

Work with Pedram Keyani, Matthew Easterday, Bilge Mutlu and Jodi Forlizzi at Carnegie Mellon University. The goal of the project is to explore

Shopper's Aid

Work with Jennifer Mankoff at UC Berkeley's IO Group. The goal of the project is to improve shopper's nutritional awareness by providing suggestions based off shopper's receipt.
