I am a tenured Professor in the Division of Hematology at The Ohio State University, with a focus on translational research in Chronic Lymphocytic Leukemia, the Associate Director for Clinical Research within the Division of Hematology, the Section Head for the CLL/Hairy cell leukemia group, and the co-leader of the Leukemia Research Program within the OSUCCC.  I am the PI for multiple early-stage clinical trials investigating novel targeted therapies for CLL and other hematologic malignancies, chaired the intergroup Phase III study A041202 which investigated chemoimmunotherapy versus targeted therapy as initial therapy for older adults with CLL, and now chair A041702 which is investigating continuous versus intermittent targeted therapy in the same patient population. My laboratory research focuses on resistance to targeted therapies in CLL.  Our group identified C481S and PLCG2 mutations as the primary resistance mechanisms for covalent BTK inhibitors and were the first to investigate reversible BTK inhibitors preclinically as a strategy to circumvent BTK inhibitor resistance.
