About

I have over 20 years of engineering and R&D experience in sensors and MEMS including physical modeling, transduction, design, optimization, fabrication, characterization/test, and algorithm development, as well as 10 years of technical management/executive experience in operations, product development, R&D, business development, marketing and technical sales. I have a track record of success in taking early stage R&D concepts through to full products, and developing and growing businesses based on those products. I hold a PhD in Electrical Engineering from the University of Florida, where I focused on sensor and instrumentation development, leading to 20 years of academic/industry experience in research, modeling, optimization, microfabrication, and testing of scientific instruments that requires in-depth knowledge of multidisciplinary physical systems (mechanical, electrical, acoustic, fluidic, thermal, and optical). I am well versed in MATLAB and LabVIEW, as well as first-principles development of lumped element modeling (LEM) for physical systems of all kinds. As the former CEO of an innovation-driven startup, my most important roles were defining the long-term vision and strategy, and building the teams and the people to make it all happen.
