Profs to Help Develop Instantly Deployable Networks
Two UT Dallas computer science faculty will be working closely with AgileMesh Inc., a North Texas company that has received $2 million from the Texas Emerging Technology Fund (TETF) to further develop its technology. “We will be helping AgileMesh build technology in the area of mobile ad hoc networks, an area of wireless networks that enables instant deployment,” said Dr. S. Venkatesan, an associate professor of computer science in the University’s Erik Jonsson School of Engineering and Computer Science. “This has immediate application in disaster areas, rescue efforts and other situations in which installed communication infrastructure does not exist or is inadequate.” Venkatesan and Dr. Ravi Prakash, also an associate professor of computer science, have more than 30 years of experience in the field. They’ll be developing methods that enhance AgileMesh’s products by significantly improving usability and performance.
Assistant Professor of Computer Science At UTD Wins Prestigious National Science Foundation Award
Dr. Ravi Prakash, assistant professor of computer science at The University of Texas at Dallas, has been granted a Career Award from the National Science Foundation (NSF) for his work in mobile computing and wireless networking. The award, worth $250,000 over the next five years, is part of the NSF’s Faculty Early Career Development program, also known as CAREER. The Career Award is the NSF’s most prestigious honor for junior faculty members and recognizes and supports the early career development activities of the teacher/scholars who are most likely to become academic leaders of the 21st century. Recipients are selected on the basis of creative career development plans that effectively integrate research and education within the context of the mission of their respective institutions. Prakash’s area of research and expertise involves mobile networks, specifically developing new solutions for mobile ad hoc networking and evaluating the performance of those solutions by computer-simulated experiments, possibly building small prototypes as research advancements are made.
Computer Science Professor Receives Teaching Award
Five UT Dallas educators were recently honored with President’s Teaching Excellence Awards for their outstanding efforts in the classroom. 
The award recipients received medallions at the University’s annual Honors Convocation on May 10. They also were recognized at an April reception hosted by the Center for Teaching and Learning, where center director and associate provost Dr. Paul Diehl said the awardees were chosen from an outstanding group of nominees from across the campus.
