C. Alexander Valencia, PhD, is a biochemist and clinical molecular geneticist who has basic and translational research programs in genomics and proteomics. His laboratory studies the biochemical mechanisms of apoptosis through a novel proteomic method called mRNA-display. Moreover, his translational research program, in the area of clinical molecular genetics, addresses the implementation of new molecular diagnostic platforms, including next-generation sequencing, in clinical genetic testing.

PhD: Ottawa-Carleton Institute of Biology, Carleton University, Ottawa, ON, 2004.

Postdoctoral Research Fellowship: Carolina Center for Genome Sciences and Eshelman School of Pharmacy, University of North Carolina at Chapel Hill, NC, 2009.

Clinical Fellowship: Clinical Molecular Genetics, Department of Human Genetics, Emory University School of Medicine, GA, 2012.
