Research/Career Interests:

Work in our lab centers around the biology and clinical application of mesenchymal stem cells (MSCs). Our current areas of focus include 1) interactions between MSCs and bacterial pathogens, and the subsequent alterations induced in MSCs; 2) use of MSCs for regenerative medicine applications in domestic animals; and 3) MSC programming (licensing) during inflammatory diseases and potential applications for MSC therapy in immune-mediated diseases in veterinary medicine.

Our lab also continues to work on tick-borne rickettsial infections of domestic animals, particularly granulocytic anaplasmosis caused by Anaplasma phagocytophilum infection and related infections. Additionally, I have an ongoing research interest in hematology and hematopoiesis of laboratory animal and non-mammalian species.
