Aaron Fields, Ph.D., is an Associate Professor of Orthopaedic Surgery at UCSF. He received his Bachelor of Science degree in Mechanical Engineering from the University of Denver in 2005, and his Masters and Doctoral degrees, also in Mechanical Engineering, from the University of California, Berkeley in 2008 and 2010. His undergraduate research was on the use of probabilistic techniques to evaluate knee implant performance, and both of his graduate thesis projects focused on discovering the mechanisms of vertebral fragility using high-resolution computational models.
