Ignacio Omar Romero, PhD


Ignacio Omar Romero is from the small town of Tulare, California. He received his B.S in Physics from the University of California, Los Angeles in 2016. In 2018, Ignacio received his M.S in Medical Physics from San Diego State University where his thesis focused on quantitative MR imaging techniques. In 2022, he obtained his PhD in Bioengineering from University of California, Merced. Ignacio’s doctoral research focused on functional X-ray imaging techniques for preclinical applications. Ignacio’s career goal is to use the skills obtained from his graduate research and residency training to help improve the quality of healthcare in the California Central Valley. In his free time, Ignacio enjoys weightlifting, playing soccer, and watching soccer and football games.

Ignacio joined the Stanford University Medical Physics Residency in 2022.
