Paul Briant
Paul L. Briant, Ph.D., P.E.
Principal Engineer
Mechanical Engineering
  • Menlo Park

Dr. Briant specializes in solid mechanics, finite element analysis, mechanical engineering, biomechanics, and digital image processing. He has applied his expertise to numerous design and failure analyses across a wide array of scales, ranging from consumer electronic components and medical devices to large piping systems undergoing water hammer events. He has extensive experience with finite element analysis and fatigue testing of medical devices, and he has assisted numerous medical device companies prepare for FDA submission. In addition, Dr. Briant has served as an expert witness in medical device litigation cases.

Dr. Briant has performed a wide range of both litigation and non-litigation mechanical engineering failure analyses to understand the root cause of reported issues. These cases include corrosion of fire hydrant components, injury analysis cases, analysis of fractured cardiovascular implants, and analyses of large dynamic structures. In addition, he has experience with digital image processing and has written algorithms for both military and non-military applications.

Prior to joining Exponent, Dr. Briant’s research focused on laboratory and numerical analysis of cartilage tissue mechanics, as well as the design and analysis of orthopaedic biomedical devices. He also has experience using lathes, milling machines, and other shop equipment, and participated in the design and fabrication of Washington University’s entry to the Formula Society of Automotive Engineers racecar competition.
