Biography

Joseph Leach, MD, PhD obtained his PhD from the joint UCSF-UC Berkeley Bioengineering program in 2009. In 2013 Dr. Leach earned his medical degree at UCSF, followed by a one-year internship at California Pacific Medical Center of San Francisco. Dr. Leach completed a four-year Diagnostic Radiology residency at UCSF in 2018. During 2017-2018 Dr. Leach was a NIH T32 Training Grant research fellow at UCSF Radiology, where he focused his research on the development of methodologies by which to study the biomechanics of abdominal aortic aneurysms (AAA) on a patient-specific basis, incorporating data from both routine clinical and more advanced imaging modalities. Dr. Leach completed a clinical fellowship in Abdominal Imaging/Ultrasound at UCSF in 2019.
Dr. Leach joined the department as an assistant professor in residence in the section of Abdominal Imaging in July 2019.
