Roberto did his undergraduate training in industrial biotechnology at the University of Puerto Rico, Mayaguez, and his M.D./Ph.D. in immunology at Stanford University. During his Ph.D. training, he studied the role of macrophages and type 2 immunity in metabolic tissues. He completed an internal medicine internship at the Brigham and Women’s Hospital, followed by a dermatology residency at the University of California, San Francisco. He has been an Assistant Professor in the Department of Dermatology at the University of California San Francisco since 2016. During his early faculty appointment, he concurrently completed postdoctoral training under the mentorship of Richard Locksley, where he studied mechanisms of innate allergy. At UCSF, he practices general medical dermatology at the Mount Zion Practice and Zuckerberg San Francisco General Hospital. Roberto became a principal investigator at UCSF in the Fall of 2021, where he leads a basic and translational skin immunology laboratory as a faculty member of the Biomedical Sciences Graduate Program and a Chan Zuckerberg Biohub Investigator. Outside the lab, he enjoys traveling, cooking, and spending time with his family.
