Associate Professor
Senior Research Scientist

I received my M.Sc. degree in EE from the Technical University of Budapest in 1989 and a Ph.D. degree in EE from Vanderbilt University in 1995. I am currently an Associate Professor at the Electrical Engineering and Computer Science Department and a Senior Research Scientist at the Institute for Software Integrated Systems (ISIS) at Vanderbilt University.

Research

My main research area is wireless sensor networks (WSN). My team has developed the first WSN-based countersniper system. The latest version is soldier wearable and not only does it localize the shooter very accurately, but it can also tell the caliber and the weapon type. A recent paper describes the system in detail. Our radio interferometric positioning approach has gained much attention and resulted in the Best Paper Award at the ACM Sensys 2007 conference. My team has recently concluded an NSF project on tracking and localization.

My other focus is Model Integrated Computing. Our widely used, open source software tool, the Generic Modeling Environment is a configurable toolkit for creating domain-specific modeling and program synthesis environments.
