Dr. Klock specializes in the analysis of coupled-physics problems involving fluid dynamics, heat transfer, and structural dynamics. In addition, he is an expert in system model reduction which identifies the underlying behaviors of complex, noisy systems in order to perform timely simulations at greatly reduced computational cost. System behaviors can either be observed from physical experimentation or high-fidelity numerical simulation such as finite element analysis (FEA) and/or computational fluid dynamics (CFD). Dr. Klock employed both experimentation and simulation during his prior work with the Air Force Research Laboratory (AFRL) Munitions Directorate on the development and analysis of rocket and scramjet-based hypersonic flight vehicles.

Dr. Klock is an alumni of the University of Michigan Aerospace Department and worked closely with NASA and AFRL on the development of hypersonic flight vehicles for:

  • Rapid and reusable access to space
  • Intelligence, surveillance, and reconnaissance
  • High value target strike

Dr. Klock is experienced in the design of structures for hot environments, high temperature materials for heat shielding, and the flexible behavior of structures under high pressure and thermal loads. Beyond his hypersonic work, Dr. Klock assisted in the design of sails for a unique concept of renewable power generation that relies on existing power lines for structural support, and is a named inventor on an associated patent. In addition, Dr. Klock is a named inventor on a patent for piezoelectric ultrasonic surgical dissectors, having proposed and experimentally validated the use of macro-fiber composites for driving and sensing dissector resonance.

Dr. Klock’s past experience also includes serving as a scientific advisor to inventors seeking to patent novel technologies or methods, assisting with the development of an autonomous fault management system for the Solar Probe Plus Spacecraft, and developing a personal navigation router to minimize travel cost, time, and carbon emissions using multiple modes of transportation.
