Dr. Andrew McCallion is a Professor at the Johns Hopkins University School of Medicine in the McKusick-Nathans Department of Genetic Medicine. His research focuses on applying functional genetics to human neurological/neuropsychiatric/neurobehavioral disease.

His work illuminates the connection between gene sequence (and variation therein) and phenotype through the integrated use of contemporary genomic strategies and model systems (mouse, zebrafish and cell culture).

Dr. McCallion received his B.Sc. in genetics from The Queen's University of Belfast. He earned his Ph.D. in genetics from the University of Glasgow. He completed postdoctoral training at Case Western Reserve University Medical School.

Prior to joining Johns Hopkins, Dr. McCallion was a project leader and staff scientist at Neuropa Ltd. (UK), a biotech startup focused on drug target development for neurodegenerative disorders.

He is a member of the International Mammalian Genome Society, American Society of Human Genetics and Federation of American Societies for Experimental Biology. He serves on the editorial board of Genome Research, and is a Faculty of 1000 faculty member in genomics and genetics.
