My laboratory has a longstanding interest in understanding the mechanisms by which the pro-apoptotic Bcl-2 family members regulate programmed cell death in hematopoietic stem and progenitor function and leukemogenesis.  We are also studying the role of programmed cell death in inflammation using a mouse model of colitis in collaboration with the laboratories of Dr. Chris Williams and Dr. Keith Wilson.   My work as a postdoctoral fellow in the laboratory of the late Stanley Korsmeyer, a leader in the field of apoptosis, focused on the role of the pro-apoptotic Bcl-2 family member Bid in myeloid homeostasis and leukemogenesis.  Using a mouse model in which Bid is deleted, I described a role for Bid in maintaining myeloid homeostasis and preventing the development of CMML.  Importantly, I discovered a novel nuclear role for Bid in the DNA damage response that is independent of Bid’s apoptotic function at the mitochondria. My laboratory at Vanderbilt University has gone on to show that Bid associates with the DNA damage sensor complex in the nucleus.  We have further demonstrated that Bid interacts with the replication protein A to regulate the DNA damage response to replicative stress. Finally, we demonstrate that Bid monitors hematopoietic function following replicative stress, and preserves hematopoietic stem cell function.  A submitted manuscript further describes a role for Bid in delaying leukemogenesis in Atm KO mice.

My background and experience place me in a particularly strong position to study signaling mechanisms of cell survival and cell death, specifically the mechanism by which the Bcl-2 family member Bid regulates bone marrow homeostasis and transformation to leukemia using novel mouse models that I have generated.  My laboratory participates in a monthly hematologic malignancies group (leukemia and lymphoma interest group) that I established, comprised of 5 groups interested in mouse models of hematologic malignancy.  I am a member of the Vanderbilt Ingram Cancer Center, the Vanderbilt Center for Stem Cell Biology, and the Vanderbilt Digestive Diseases Research Center.
