Research Interests

My laboratory has been funded by the NIH since 2001 and has a long-term interest in oxidant generation and mitochondrial damage during renal ischemia/reperfusion, as it relates to transplantation injury. The laboratory is currently focusing on elucidation of specific pathways involved with mitochondrial quality control (especially the fusion pathway) that are altered during renal transplantation. In addition, we are examining the therapeutic potential of several agents to block renal mitochondrial injury during warm and cold ischemia, using cell and rat models of transplantation. This research has led to a Use Patent and Phase I Small Business Grant from NIH. Another recent area of study is focused on development of the first activity assay for the mitochondrial protease OMA1, along with identification of novel OMA1 inhibitors using library screening. This project involves multiple collaborators across the county including NCATS and Cayman Chemical Company. Finally, our lab is also working in collaboration with Dr. Nancy Rusch’s laboratory, on a project that is exploring the role of a novel mitochondrial large conductance potassium channel has in mitochondrial damage during renal transplantation.
