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. Beginning in 2007, I have built my own research group as an independent investigator in the department of Anatomy at UCSF. I am currently a tenured Associate Professor, and my research group consists of a team of twelve staff members, graduate students, postdoctoral fellows, and Master’s students.

Our laboratory is interested in genetic lesions that lead to abnormal Ras signal transduction events and development of diseases such as autoimmunity and cancer. Active Ras communicates to many downstream targets and affects many cell biological responses. The potency of active Ras is illustrated by the fact that activating mutations in the Ras genes are among the most common genetic lesions leading to cancer.

Our goal is to understand the mechanism of activation of the small GTPase Ras by Ras exchange factors, comparing normal physiology with pathology. We collaborate with many different groups and benefit from these collaborations by tapping into computational models, biophysical approaches, structural insights, and patient samples. We combined these collaborative efforts with our own expertise in the biochemistry of Ras signal transduction, cell line approaches, and various mouse models.

There are four main directions in the lab:
1. Mechanistic understanding of Ras activation by Ras exchange factors.
2. Altered Ras-kinase signaling in autoimmune T cells.
3. Interfering with oncogenic Ras signals in leukemia.
4. Ras exchange factors in epithelial cells and carcinoma.

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