Matt Halvorsen
Matt received his PhD in Bioinformatics and Computational Biology from the University of North Carolina at Chapel Hill, and joined the CHGV in January 2013.   He focuses on using genetic variants in cases with neurological disorders to identify genes whose dysfunction is involved in the resultant phenotype, as well as advancing the interpretation and prioritization of noncoding genetic variants.
