Kate (Puikei) Cheng, Ph.D.

Associate
Mechanical Engineering
Chicago - Downtown

Dr. Cheng specializes in computational mechanics, focusing on the modeling of metal deformation as well as additive manufacturing processes. Her particular expertise within this area is in thermal and mechanical finite element modeling (FEA) of metal plasticity, damage, and microstructural-based models using commercially available software (such as Abaqus and LS-DYNA).

Prior to joining Exponent, Dr. Cheng performed research in optimizing toolpath design of additively manufactured parts. During her Ph.D. studies, she performed research in collaboration with Ford Motor Company to develop software for modeling the deformation and failure of uni-directional and woven polymer matrix carbon fiber composites. Additionally, she has experience in large-scale data analysis (using Matlab and Python), parallel and high-performance computing, image processing, complex data visualization, and experimental collection and design.
