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. Aaron was appointed to a faculty position at UCSF after completing his post-doctoral fellowship in Orthopaedic Surgery in 2015. His background includes extensive research in experimental and computational biomechanics. Aaron is an active member of the Orthopaedic Research Society, the American Society for Bone and Mineral Research, and the American Society of Mechanical Engineers.
