Dr. Cheng specializes in computational mechanics, focusing on the modeling of metal deformation and manufacturing processes. She has extensive experience in thermal and mechanical finite element modeling (FEA) of plasticity, damage, and microstructural-based models. At Exponent, Dr. Cheng has assisted with the analysis of mechanical components involved in intellectual property disputes and accident investigations.
Prior to joining Exponent, Dr. Cheng completed her Ph.D. at Northwestern on toolpath design for additive manufacturing. During her studies, she also 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, data acquisition, and experiment design.
