Research Interests:

Signal Transduction Pathways in Prostate Cancer
The pathways we study include the phosphatidylinositol 3-kinase (PI3K)/Akt pathway, the Ras/Raf/MEK/MAPK pathway and other signaling pathways both upstream and downstream of these. This includes the mammalian target of rapamycin (mTOR) pathway, and signaling by the epidermal growth factor receptor (EGFR), related receptor tyrosine kinases ErbB2 and ErbB3.
