Research Summary

I obtained my PhD in The Netherlands where I investigated Wnt signaling and cancer in the lab of Dr. Hans Clevers. I subsequently studied Ras signaling in lympohcytes during my postdoc in the lab of Dr. Arthur Weiss at UCSF. Since 2007 I built my own research group as an independent investigator in the department of Anatomy at UCSF. I am currently a tenured Associate Professor with a team of staff members, graduate students, postdoctoral fellows, and Master’s students. Our focus is on Ras-kinase signaling an implications of signal alterations in human disease,

Half of my group currently focuses on various aspects of Ras signaling and cancer. We have published on the leukemic role of the Ras activator Rasgrp1 in both T cell leukemia and in myeloid leukemia. We reported on two biochemically distinct oncogenic Ras signals in T cell leukemia. We continue this research area with the goal of improving molecular therapy for leukemia patients. We expanded our research to carcinomas and reported that the EGFR sends not only growth-stimulatory cues in colorectal cancer but also growth-restricting signals, depending on the use of the SOS1- or RasGRP1- Ras activators.

We are part of the Biomedical Science (BMS) Graduate Program, the Immunology Program, the Helen Diller Family Comprehensive Cancer Center, and the Stem Cell Center. For more information on research directions, projects, and publications, please visit our website at
