Research Experience

Composable Simulation: Adtranz (09/99 - Present)
Creating a framework that will verify and maintain consistency between the function, form and behavior of an electromechanical device. This will reduce the time needed for new product realization, improve design quality and correctness and decrease prototyping costs.
DARPA RaDeo Program: Raytheon and Boeing (02/97 - 05/99)
Defined a modular, hierarchical model of the kinematics behavior of an electromechanical device and designed algorithms to automatically derive the model from the geometry. This improves design quality.
