RESEARCH EXPERIENCE

·         Graduate Research Assistant, Rescue Project, University of California Irvine and Calit2 (September 2004 to current)                                                                                   

I am currently working on MetaSim - the primary testbed that is currently being developed in the Rescue project to test IT solutions in the context of disaster response. METASIM is a framework to support a collection of simulation tools developed to test the efficacy of new and emerging information technologies within the context of natural and manmade disasters, where the level of effectiveness as measured by reduction in expected losses, evacuation times, and other impacts can be determined for each technology developed. Simulation models running on computers at different locations are connected together to create a meta-simulation capability that allows the assessment of the larger impacts of a disaster. Within this larger testbed framework we are developing a micro level activity simulator (DrillSim) at UCI. DrillSim is a multi-agent response activity simulator which models the response activity at the micro level, thereby enabling integration of technology by observing the impact of technology in the behavior of people who are modeled as agents. I am exploring data representation and scalability issues to improve the scalability and efficiency of these systems which are highly dynamic in nature.

  • Graduate Research Assistant, SUGA Project, University of California, Irvine (Sep 2001 – Sep 2004)

I worked on content adaptation for universal accessibility in the Distributed Systems Middleware group. The goal of the SUGA project is to make multimedia information accessible irrespective of user, system and environmental restrictions, with the current focus on accessibility to users with disabilities. Policies to adapt multimedia information according to specific types of disabilities have been designed both at content level and interface level. GURU an MPEG-4 based distance learning framework that can modify MP4 content according to users’ requirements is the artifact as a result of this research effort.

 

SELECTED PUBLICATIONS

 

PROJECTS

·         DrillSim (September 2004 to current): It is a micro-level response activity simulator developed as part of Rescue and Responsphere for the purpose of testing IT solutions in the context of a crisis response. It is a multi-agent simulator for simulating campus level crisis response activities. It has plug and play capabilities where models and IT solutions can be incorporated into the system.

·         MetaSim (January 2006 to current): METASIM is a highly distributed collection of simulation tools connected by a series of translators that access a common database. Simulation models running on computers at different locations are connected together to create a meta-simulation capability that allows testing effectiveness of IT solutions in the context of disaster response. Models simulating various aspects of a response activity do not have to develop protocols for data transfer with individual simulators, but are able to share simulation results through a common enterprise database. METASIM has standardized communication protocols to allow other simulation models to be incorporated without redesigning the system.

·         GURU an MPEG-4 Based Distance Learning Environment for Users with Disabilities (Jan 2003 –September 2004)

It currently being developed under the SUGA project at UCI, that supports cross disability access. The distance-learning framework is built on top of the MPEG-4 framework and supports the adaptation techniques developed as part of the SUGA project. Dynamic adaptations for modifying information according to users requirements are being implemented either as MPEG-J API’s or built into the MPEG-4 layer. The interface is being developed to contain the intelligence to dynamically profile the user using feedback techniques.

·         Proxy Transcoding of Multimedia Information for Cross Disability Access  (Class Project- Distributed Systems Middleware course, Apr 2002 – July 2002)

In this project we developed selection techniques for server-proxy combinations in a distributed environment that was based on user demographics and statistical studies. The best server-proxy combination was based on availability of information, proximity of the server and proxy to the request and ability of the proxy/server to provide accessible information to the user.
