Issam Ben-Sahra

Postdoctoral Fellow:

2011 -

Education:

Ph.D. 2010, University of Sophia Antipolis, Nice, France

Research Interest:

Issam is interested in understanding the impact of mTOR-stimulated metabolic pathways on the properties of cells and tumors with specific upstream oncogenic events.  He is focused on revealing how metabolic changes common to tumor cells can differentiate them from their tissue of origin, with a focus on revealing novel therapeutic opportunities.
