Biographical Sketch 
John Charles Chatham was born in Didmarton, Gloucestershire, England in May 1960. He received a B.Sc. (Hons) degree in Chemistry from the University of Southampton England (1983) and a D.Phil. in Biochemistry from University of Oxford (1987). In 1987 he moved to the USA first to a postdoctoral fellowship at Huntington Medical Research Institutes, Pasadena, CA and then to Department of Radiology at Johns Hopkins University School of Medicine. After his postdoctoral training he joined the faculty at Johns Hopkins School of Medicine first as an Instructor and then as an Assistant Professor in the Department of Radiology. He earned the title of Associate Professor of Medicine after coming to UAB in 2000. In 2011 he was appointed as Professor and Director of the Division of Molecular and Cellular Pathology in the Department of Pathology at UAB and Co-Director of the UAB Comprehensive Cardiovascular Center. He served as Chair of the UAB Faculty senate 2011-2012 and was Chair of the Science Policy Committee for the American Physiology Society from 2010-2013.

Research/Clinical Interest
Cardiomyocyte function and survival in ischemia/reperfusion and the impact of diabetes:
The primary goal of his laboratory is to understand the adverse effects of diabetes on cardiomyocyte function. Over the past 10 years his laboratory have focused on understanding the role of O-linked-N-acetyl-glucosamine (O-GlcNAc) modification of proteins in mediating cardiomyocyte stress responses. We have demonstrated that acute activation of O-GlcNAc levels is remarkably cardioprotective; conversely, in the setting of diabetes where O-GlcNAc levels are chronically elevated cardiomyocytes cell survival pathways such as autophagy are impaired in an O-GlcNAc dependent manner. More recently, his group has been involved in understanding the role of store-operated calcium entry (SOCE) pathways in regulating cardiomyocyte function, which included the generation of a cardiomyocyte-restricted STIM1 KO mouse model. STIM1 plays a central role in regulating SOCE and we demonstrated that a lack of cardiomyocyte STIM1 resulted in metabolic and mitochondrial dysfunction ultimately leading to a dilated cardiomyopathy. These were the first studies to demonstrate that STIM1 is essential for regulating cardiomyocyte homeostasis. For more information about the role of animals in research I recommend the following: Speaking of Research; Americans for Medical Progress; Foundation for Biomedical Research; Animal Research Information.
