Ludwig Professor in Cancer Research, Chairman of the Department of Radiology at Stanford University School of Medicine, and a professor by courtesy in the departments of Bioengineering and Materials Science and Engineering at Stanford University. Additionally, he served as the Director of the Molecular Imaging Program at Stanford (MIPS), Canary Center at Stanford for Cancer Early Detection and the Precision Health and Integrated Diagnostics Center (PHIND). He authored 680 publications and had over 40 patents pending or granted. His work was featured on the cover of over 25 journals including the Nature Series, Science, and Science Translational Medicine. He was on the editorial board of several journals including Nano Letters, Nature Clinical Practice Oncology, and Science Translational Medicine. He was founder/co-founder of several biotechnology companies and also served on the scientific advisory board of multiple companies. He mentored over 150 post-doctoral fellows and graduate students from over a dozen disciplines. He was known for his work in molecular imaging of living subjects and early cancer detection.

## Personal

Gambhir was born in Ambala, India, and moved to the US with his parents and sister in 1969. He was raised in Phoenix, Arizona. He was married to Aruna Bodapati Gambhir and lived in the Bay Area. He died July 18, 2020, of cancer of unknown primary. His son, Milan Gambhir, was born in 1998 and died from a glioblastoma in 2015.

## Education and employment

Gambhir was a Phi Beta Kappa graduate of Arizona State University where he received his BS in physics. He then entered the combined MD–PhD Medical Scientist Training Program (MSTP) at the University of California Los Angeles (UCLA) and received his MD, and his PhD in biomathematics.
His first academic appointment was in 1994, at UCLA, as an assistant professor of molecular and medical pharmacology. He was a clinical attending in the Nuclear Medicine Department at the Center for Health Sciences at UCLA starting in 1997. He was appointed tenure professorship at UCLA in 2003. In 2003, he moved to Stanford University and was appointed professor of radiology, head of nuclear medicine, director of the Molecular Imaging Program at Stanford (MIPS), director of the Precision Health and Integrated Diagnostics (PHIND) Center, division chief of the Canary Center for Cancer Early Detection, and member of the Bio-X Program. He became the Virginia and D.K. Ludwig Professor for Clinical Investigation in Cancer Research, which is an endowed professorship, in 2009. He was appointed the chair of radiology in August 2011.
