Research Interests:

Natural killer (NK) cells express activating and inhibitory receptors, termed the Natural Killer Receptor Repertoire (NKRR), that are expressed in a variegated manner with individual receptor frequencies and densities determined not only by promoter strength, but also by the presence of MHC-I ligands. The signaling inputs from the activating and inhibitory receptors expressed by an individual NK cell determines it’s ability to respond to an infected or malignant cell. Mice with germline deficiency in SHIP1 have severe NK cell dysregulation, including increased NK cell numbers, deregulated NKRR and inability to reject an MHC-mismatched bone marrow graft. It is unknown if NK cell dysfunction is due to intrinsic effects of SHIP1 in NK cells or due to the effect of SHIP1 deficiency in other immune cell types that leads to an inflammatory milieu in SHIP1-/- mice. Using a mouse model that enables NK selective ablation of SHIP1 expression, NCR1iCreSHIP1flox/flox, we have begun to assess if the defects noted previously are recapitulated in mice where only NK-lineage cells lack SHIP1 expression.

Dr. Arthur Kornberg (a Nobel prize winner in medicine in 1959) once said, "basic research is the lifeline of medicine." And if I could extend his comment, I would add, "and publication is the lifeline of medical research." I think publishing one's work serves two important roles. The first is to communicate your work to the larger scientific community, and the second is to serve as a landmark for the completion of one aspect of your work, thus providing direction for the future scientific work. As a future physician scientist here at Upstate, I have numerous opportunities to get involved in activities and trainings to improve our skills needed for publications.
