Buddhika Kottahachchi

I am a graduate student at MIT CSAIL, currently working with Howard Shrobe, Robert Laddaga and the members of the AIRE Research Group.

My research interests include, but are not restricted to, applications of security, dynamic role-based context-aware access control mechanisms, collaboration support, and infrastructure for pervasive computing and intelligent environments.

I also maintain a personal website here.

Projects

At present, I'm working towards a Master of Engineering degree on a project exploring frameworks for building secure intelligent environments. A research abstract of this project can be found here. This work is being done in conjunction with the Hyperglue Project.

A list of projects I've contributed to in the past, is listed below (more to come as I organize things):

Technical

• Galaxy Integration for the OK-Net Kiosk Project (assisting the OK-Net core group)
  As part of the demos put together for the Oxygen Alliance's annual conference, I assisted the OK-Net core group perform integration with the Galaxy Speech platform thus enabling users to interact with OK-Net kiosks via speech. A very low-quality, unofficial video showcasing their functionality is available in MPEG (27.4 MB) and WMV (3.6 MB) formats. Functionality for this demo included Directory and Map lookups within the Stata Center where kiosk prototypes are currently deployed and used.
