Research Summary

My research interests involve the role of Bcl-2 family of proteins in oncogenesis. Our recent studies have examined potential novel therapies for the treatment of lymphoma.  We have initiated studies of human specimens.  In an effort to facilitate more translational research, I became the Director of the Tissue Procurement Core in 2010.  During this time we have collaborated with a number of investigators in the consenting and collection of tissue specific specimens including Breast cancer, melanoma and sarcoma.  With this experience the TPC is well positioned to help with the collection, storage and distributions of neuroendocrine tumors.  We are anxious to help with the studies in any way we can.
