Mr. Tchoryk has cross-functional experience spanning domestic and international business development, strategic business planning and forecasting, engineering operations, project management, and engineering development, including six patents granted and two pending. He received his Masters in Electrical Engineering from the University of Michigan in 1994 and his Bachelors in Electrical Engineering from GMI (Kettering University) in 1986.

David K. Johnson

President, Chief Scientist


David Johnson received his Ph.D. in Engineering/Applied Mathematics from the University of Akron. He has over 20 years of experience in the mathematical modeling of physical phenomena. During his career he has applied his expertise to a wide variety of problems. He worked on inverse problems in Electromagnetic Scattering while doing his graduate research at NASA-Lewis Research Center. Later he modeled problems in Computational Fluid Dynamics and Heat Transfer while at Ford and Visteon. Dr. Johnson solved inverse problems for parameter estimation and blind de-convolution in Radar Systems and Specific Emitter Identification while at General-Dynamics Advanced Information Systems. He currently serves Michigan Aerospace Corporation as President and Chief Scientist, leading work on all levels of the process of technology development from project management to experimental design and testing to production, as well as the scientific support of MAC programs including developing techniques for the solution of inverse problems for remote sensing and signal processing.

Matthew J. Lewis

Vice President


Matthew Lewis received his Ph.D. in physics from the University of Michigan for his work describing cosmological models in the context of string theories. After graduating, he worked for eight years in the defense industry, at General Dynamics Advanced Information Systems, focusing on the application of machine learning techniques to defense and intelligence problems, particularly in the realm of electronic warfare. Matthew served as principal investigator for the $20M DARPA Retriever program, as well as many other electronic warfare and machine learning programs for the Navy, NSA, and other U.S. Government agencies. Matthew currently applies machine learning technology to problems such as clean energy and early-stage disease detection. Over the last decade there have been dramatic advances in machine learning and artificial intelligence, and Matthew is working to bring these advances to a wider audience via MAC and its clients.

Dominique Fourguette

Vice President of R&D


Dominique Fourguette is the Vice President of Research & Development at Michigan Aerospace Corporation. She has more than twenty years of experience in optical diagnostics techniques and has been the lead scientist on the development of optical detection techniques, integrated optics-based instrumentation, and micro-sensors. Dominique has over twenty publications in optical diagnostics and related fields, and has co-authored three patents in sensor development. Dominique was visiting scientist for eighteen months at the Combustion Research Facility at Sandia National Laboratories in Livermore, CA, and Senior Research Fellow in the Graduate Aeronautics Laboratories at the California Institute of Technology, where she investigated an array of planar imaging techniques. Dominique developed a real-time micron-size optical particle sizer that was successfully used in several tests at White Sands Missile Range between 2002 and 2004. Dominique earned a Ph.D. from the Center for Laser Diagnostics at Yale University and a B.S. in Acoustics and Mechanical Vibrations from the Université of Compiègne (Compiègne, France). She is an Associate Member of the American Institute of Aeronautics and Astronautics (AIAA), and a member of the Aerodynamic Measurement Techniques Technical Committee of AIAA, of which she served as Chair from 2004 to 2006. At MAC, Dominique fully leverages both her R&D and academic experiences and networks to facilitate both the technological and the financial aspects of realizing MAC’s clients’ ideas.

Dominic Spadafore

Chief Commercialization Officer


Dominic Spadafore has spent his career helping to commercialize a diverse collection of medical devices contributing to improved patient care both domestically and internationally. For the last 12 years his focus has been on early stage technologies including the locally based Somanetics Corporation, where he led the commercialization effort to introduce a new hemodynamic vital sign used to assure adequate tissue perfusion. Most recently his efforts have been in a consultative role helping start-ups and early stage companies launch new technology into the various healthcare markets. Dominic is excited to join forces with Michigan Aerospace and truly fill all of the gaps that prevent so many important technologies from getting to those in need.

Lennard A. Fisk

Co-Founder, Chairman of the Board


Lennard Fisk is the Thomas M. Donahue Distinguished University Professor of Space Sciences in the Department of Atmospheric, Oceanic, and Space Sciences at the University of Michigan, where he also served as Chair from 1993-2003. Prior to joining the University, Dr. Fisk was the Associate Administrator for Space Science and Applications of the National Aeronautics and Space Administration (NASA). In this position he was responsible for the planning and direction of all NASA programs concerned with space science and applications and for the institutional management of the Goddard Space Flight Center in Greenbelt, Maryland and the Jet Propulsion Laboratory in Pasadena, California.

Prior to becoming Associate Administrator in April 1987, Dr. Fisk served as Vice President for Research and Financial Affairs at the University of New Hampshire. In this position, he was responsible for the administration of the University research activities and was the chief financial officer of the University.
