CVI Research Description:
I am a clinical pathologist and apheresis physician with a research interest in laboratory hematology and transfusion medicine. I have a special interest in understanding the pathophysiology of thrombotic thrombocytopenic purpura (TTP), a blood disorder that causes thrombocytopenia, anemia, renal dysfunction, and neurological changes. I am also involved in developing assays for the von Willebrand protein cleaving protease ADAMTS13 and studying the role of anti-ADAMTS13 autoantibodies in TTP.
In addition, I collaborate with basic and clinical researchers who are interested in determining the hematological effects of various experimental conditions on peripheral blood counts in humans and other experimental models of disease.
Dr. Shelat is interested in thrombotic thrombocytopenic purpura (TTP) and its treatment and has developed assays for the von Willebrand protein cleaving protease ADAMTS13.
He also collaborates with investigators interested in determining the hematologic phenotype in experimental animal models of disease (analysis of white blood cells, red blood cells, platelets, and reticulocytes).
I am a clinical pathologist and apheresis physician with an interest in laboratory hematology and transfusion medicine. I collaborate with basic and clinical researchers who are interested in determining the hematological endpoints in their animal models of disease, including complete blood counts (CBC), white cell differentials, and reticulocytes.
