I was affiliated with the Daedalus and MASH projects, and finished my dissertation under the auspices of the Ninja and Endeavour projects. I was advised by Prof. Randy H. Katz. My dissertation is titled Discovery and Adaptation for Location-based Services

Relevant interests include:

• location-dependent applications for mobile devices
• scalable service advertising: wide-area service discovery, and its application to file sharing
• software for remote control of devices and applications
• composition of network services from lightweight, heterogeneous clients

Software

• SDS-DL: SDS Distributed Lookup software package (available in the Ninja CVS tree) aka, wide-area querying in the Ninja Service Discovery Service

• Room Controls for Soda Hall, implemented as part of the MASH (now OpenMash) toolkit, for room 326 and with the BMRC folks for room 405.

• Rvic is a client/server "remote-control" version of the videoconferencing tool vic, described in the MMCN99 paper (above). It is integrated with the Room Controls.
