Meet Our Leadership Team

Inmatech’s technologies have been developed and patented by our company founders, who came together through the University of Michigan in Ann Arbor. In collaboration, they combine their expertise in materials, electrochemistry, product development, prototyping, and entrepreneurship.

Professor Levi Thompson, Chairman of the Board and Co-Founder

Professor Levi ThompsonLevi’s leadership at Inmatech focuses on the design and development of nanostructured materials for use, as well as electrodes for energy storage devices.

As an entrepreneur, he co-founded TJ Technologies (acquired by A123, a leading producer of lithium ion batteries) and owns intellectual property in the field.

Currently at the University of Michigan, he is the Richard E. Balzhiser Professor of Chemical Engineering, a Professor of Mechanical Engineering and the Director of the Hydrogen Energy Technology Laboratory.  He presently serves as member of the DoE Hydrogen Technology Advisory Committee and AIChE Chemical Engineering Technology Operating Council, among others.

At the University of Delaware, he earned his B.ChE and M.S.E. degrees in Chemical Engineering and Nuclear Engineering. At the University of Michigan, he earned his Ph.D. in Chemical Engineering. He is a recipient of multiple awards including National Science Foundation Presidential Young Investigator Award, Carbide Innovation Recognition Award and Dow Chemical Good Teaching Award.

Les Alexander, Chief Executive Officer

Les Alexander, CEOLes brings financial, operations and business development experience to Inmatech. He currently is the senior executive responsible for mobilizing Inmatech to develop and commercialize super capacitors for emerging power and energy markets.

He retain his position at A123 and post A123’s successful IPO, Mr. Alexander became the General Manager of A123 Government Solutions Group. This group managed over $500M in government programs for A123 Systems. Mr. Alexander recently joined Inmatech after two years as General Manager of Navitas Advanced Solutions Group. Mr. Alexander earned a B.A. in Economics (Finance / Management) from University of Pittsburgh and M.S. in Management (Government Contracting) Naval Postgraduate School.

Dr. Saemin Choi, Chief Technology Officer and Co-Founder

Dr. Saemin ChoiSaemin brings to Inmatech over a decade of experience in the formulation, characterization and evaluation of advanced catalyst and electrocatalytic systems for fuel processing and energy storage systems.

Currently he is the principal investigator for government funded projects from the National Science Foundation and United States Department of Agriculture. He also led the development program for novel nanostructured electrodes for high energy density Li-ion batteries, funded under the UM-Fraunhofer Alternative Energy Technologies for Transportation program.

Previously, he worked as an engineering manager at Visteon Corporation. He led the development of fuel processors for residential applications, and thermal and fuel systems for advanced powertrain systems, including hybrids and fuel cell vehicles for global automotive OEMs.

At the Yonsei University in Seoul, Korea, he received both a B.S. and M.S. in Chemical Engineering. At the University of Michigan, he earned a Ph.D. in Chemical Engineering.

Dr. Paul Rasmussen, Director of Scientific Research and Co-Founder
