Peter has led teams that identified mutation in genes for Parkinson’s disease (PD), frontotemporal dementia (FTD), chorea, ataxia, hemochromatosis, porencephaly and various development disorders. He has also made important contributions to genome wide association studies (GWAS) for major depression, Tourette Syndrome, obsessive compulsive disorders, FTD, and PD. Additionally, Peter has made contributions to a series of GWA, exome and whole genome sequencing studies as a member of the International Parkinson’s Disease Genomics Consortium (IPDGC), the International Frontotemporal Dementia Genomics Consortium (IFGC) and the International FTLD-TDP WGS consortium and is a member of the steering committee of the Global Parkinson’s Genetics Program. Peter has been involved in many industry collaborations to bring genetic findings toward the clinic and is an author or co-author of more than 400 peer-reviewed publications.
