Dr. Coudrillier specializes in solids mechanics, mechanics of soft tissues, mechanical engineering, and image processing. He has in-depth experience in finite element analysis, experimental characterization of materials, and medical imaging, which he uses to assist clients in solving problems.

Before joining Exponent, Dr. Coudrillier was a graduate research assistant in the department of Mechanical Engineering at Johns Hopkins University and then a postdoctoral fellow in the department of Biomedical Engineering at Georgia Institute of Technology and Emory University. His research focused on understanding the mechanisms leading to vision loss in glaucoma, the second most common blinding disease in the US. This included developing experimental testing equipment and finite element models of the eye to understand the effects of elevated intraocular pressure in the disease. He also gained expertise in diffraction techniques to characterize the microstructure of collagen-rich soft tissues. Through his graduate work, he developed a strong background in the characterization of the mechanical behavior of nonlinear elastic and anisotropic biological tissues. In his postdoctoral work, he developed a novel x-ray micro-tomography imaging method to study the microstructure of soft tissues and strengthened his expertise in the structure/property relationship of soft composite materials. He is also experienced with cell culture, protein assays, and microscopy techniques. Dr. Coudrillier has mentored over 10 undergraduate and graduate students throughout his time in academia, and has served as a teaching assistant for the graduate courses: “Nonlinear Continuum Mechanics,” “Biosolid Mechanics,” and “Computational Solid Mechanics,” at Johns Hopkins University.
