I am interested in unveiling the precise molecular mechanisms responsible for cold storage (CS)-induced renal damage. My research focuses on exploring novel mechanisms by which CS damages mitochondria and importantly, to identify a possible therapeutic target that could lead to improved mitochondrial function before and after transplantation. Specifically, I plan to investigate the role of proteasome in mediating mitochondrial damage and renal dysfunction after CS and transplantation. We have established a syngeneic rat kidney transplantation model in Dr. MacMillan-Crow’s laboratory(my post-doctoral mentor), which will be fundamental in studying my independent research project on proteasome mediated mitochondrial and renal damage. In addition, I’m also collaborating with Dr. MacMillan-Crow to study the molecular mechanisms that disrupt mitochondrial dynamics during renal CS and transplantation using our rat kidney transplant model.
