Christina Aperjis

I am a Ph.D. candidate in Operations Research at Stanford. My advisor is Ramesh Johari.

In the fall, I will join the Social Computing Lab at HP Labs.

My research focuses on providing incentives for efficient outcomes in settings with rational agents who act in their self interest.
I have worked on two such settings: electronic markets and peer-assisted content distribution.
In the former, the goal is to achieve efficient trade; in the latter, it is efficient allocation of network resources.
I have studied how these goals can be achieved through reputation mechanisms (in online marketplaces) and prices (in content distribution).
