Expert in Piezoelectrics, Sensors, and Embedded Systems
Expert ID: 735705 Florida, USA
I have worked with piezoelectric materials, BAW & SAW devices, their packaging, and the associated RF electronics from tens of MHz to >1500 MHz throughout my career. This effort has ranged from design engineer to senior management. As CTO/VP Engineering at BiODE, I drove the commercialization of viscosity sensors based on langasite crystal oscillators. Our team sold the start-up company to Dover Corporation’s Vectron Technologies BU in 2007, giving all investors a profitable exit.
At Vectron I led the sensor R&D team until 2011. After transfer of the viscosity IP, this US-based team leveraged two Vectron factories in Germany and several Asian strategic partners to introduce a temperature monitoring solution using passive, wireless SAW resonator sensor technology for Smart Grid asset monitoring. In 2011 most of the team left Vectron to form IntelliSAW, where I served as VP of Research & Development. My team has optimized a complete system for electric power asset monitoring, resulting in the acquisition of IntelliSAW by Emerson’s Rosemount Division in October, 2015.
Other than the period November 2016 to May 2017, during which I took a position with Mnemonics, Inc addressing time-encoded wireless SAW sensors, I served as Director of R&D at Rosemount IntelliSAW. In addition, I have performed consulting work for various clients including utility marker detection, novel solar power meta-structures, implantable wireless sensors, and various embedded projects.
I presently serve as a Director of Research and Development in the Rosemount Measurement Division.
My skills include wireless, wireless sensors, RF design, mixed signal design, embedded systems design, firmware and software development, and antenna design. These responsibilities have included all aspects, such as materials science, device modeling & design, circuit design & layout, troubleshooting & improvement, product conceptualization & design, and certification for sensor systems, embedded instrumentation, and RF hardware. This has included direct responsibility for IEC61000-6-5, UL61010, RTT&E EN300-220, and FCC part 15.231 approvals. I actively and simultaneously perform as a manager and a contributor on multiple projects.

The executive team that I assembled secured over $2M in Angel investment, launched products (including UL Hazardous Locations certification), and made initial sales into key markets. We sold the company to Dover’s Vectron operating company, resulting in a profitable exit to all investors. We were the first company to ever repay the Maine Technology Institute’s seed money loans and grants.
