My current research interests are virtual machine scheduling and management for efficient resource utilization. I'm currently leading the Usher Project. Usher is a virtual cluster management system which strives to multiplex virtual clusters on a given set of resources according to a prescibed policy. For more information, visit the Usher project web site.

I previously led the Wireless Topology Discovery (WTD) project. For more information, check the Wireless Topology Discovery project page.

Usher. An extensible virtual machine management system. See the Usher Website for further information. Language: Python.

WTD. Wireless topology discovery collection software. This software runs on Windows CE PDAs and periodically samples, stores, and uploads signal strengths of all detected access points to a remote Firebird database. See the WTD page for further information. Language: C++.

gScat. Gravitational scattering simulator. A time-reversible, energy conserving simulator for the close approach 2-body problem. Smoothly switches between low and high order integrators during close approaches. Language: C++. Tags: N-body, geometric integration.
