Torstens Skujins, Ph.D., P.E.
Senior Engineer
Mechanical Engineering
Menlo Park

Dr. Skujins’s background is in mechanical and aerospace engineering, and he has expertise in structural analysis, fluid flow, and fluid-structure interaction. At Exponent, he has experience assisting clients dealing with problems throughout a range of areas, including wind turbines, industrial equipment, food processing equipment, and industrial safety.

Dr. Skujins has investigated wind turbine issues involving blade failures of both horizontal and vertical-axis wind turbines, remaining life estimations of wind turbines, and potential leading edge erosion problems. He also has extensive experience analyzing different types of industrial equipment, including mining equipment, forklifts and other industrial vehicles, dock levelers, and other equipment. Specifically within the realm of food processing and agricultural equipment, Dr. Skujins has experience evaluating machinery used for handling and/or harvesting an array of produce items, including nuts, tomatoes, lettuce, and potatoes. Finally, Dr. Skujins has experience investigating safety-related issues pertaining to industrial plants and equipment.

Prior to coming to Exponent, as a graduate student, Dr. Skujins was a part of the Michigan-AFRL Collaborative Center in Control Science (MACCCS), an Air Force-sponsored effort to develop a six degree-of-freedom hypersonic vehicle controls simulation framework and then to use that framework to study vehicle controllability. Dr. Skujins developed a computationally efficient model for the calculation of unsteady aerodynamic loads for general vehicle configurations which could be used throughout the duration of a hypersonic vehicle’s entire flight, from subsonic up through hypersonic speeds.
