Research Areas

Statement of Research:
My main research interests are in the areas of geometric computing, bio-medical computing, parallel (multicore, GPU) computing, and intelligent transportation systems. I am particularly interested in developing computationally efficient algorithms for optimization problems. Some of the emerging computational fields, such as computational medicine and intelligent transportation are dealing with problems that can make use of geometric and graph optimization techniques. My research aims to bring computational geometry and geometric optimization methods to the forefront of other computational fields.
Research Interests:
  • Computational Geometrys
  • Algorithms and Optimization
  • Bio-Medical Computing

NSF Brings Together Computer Scientists, Industry for New Tech Hub
Computer scientists at UT Dallas hope that funding awarded by the National Science Foundation to create an Industry/University Cooperative Research Center will help the Dallas area become a research hub for technology that enhances human abilities.

Like all I/UCRCs, the iPerform Center for Assistive Technologies to Enhance Human Performancesupports research that interests university and industry members. The center originated with two sites, one at UT Dallas and the other at the University of Texas at Arlington. The NSF awarded UT Dallas $325,000 for five years to create iPerform, with the expectation that researchers involved would attract industry partners that pay a fee to fund precompetitive research and have access to other research at the center. Researchers at UT Arlington have received separate funding to participate in iPerform and also are attracting partners.
