Stephen Kreuzer
Steven M. Kreuzer, Ph.D., P.E.
Senior Engineer
Mechanical Engineering
  • Natick

Dr. Kreuzer specializes in finite element modeling and molecular dynamics as well as the design and execution of custom mechanical tests. He has applied his expertise to a range of engineering fields, including tissue engineering, protein / molecular mechanics, consumer electronics, automotive, aerospace, and biomedical applications. Dr. Kreuzer provides expertise to clients seeking to combine experimental testing with insights gained from computational approaches.

While at the University of Texas at Austin, Dr. Kreuzer’s doctoral research involved the development of simulation techniques for determining the mechanical properties of proteins and protein assemblies in healthy and diseased cells. These simulations determined the response of proteins and polymers under the influence of mechanical forces and displacements based on atomic interactions. As an undergraduate, Dr. Kreuzer’s research focused on performing finite element analysis and computational fluid dynamics simulations to determine the mechanical environment of maturing and remodeling musculoskeletal tissues. As a doctoral student at the University of Texas at Austin, Dr. Kreuzer was a teaching assistant with 6 years of experience in laboratory courses focused on the design and implementation of mechanical tests.
