CCXDP Investigator News
Ben Kleinstiver, PhD Receives Oustanding New Investigator Award
August 11, 2021 – Congratutations to Ben Kleinstiver, PhD, who recently won the Oustanding New Investigator Award from The American Society of Gene & Cell Therapy for his work in genome editing. Dr. Kleinstiver has been a member of the CCXDP consortium since 2015, first as a postdoctoral fellow in the laboratory of Keith Joung, PhD and now as an independent investigator in the Center for Genomic Medicine at Mass General. His current work with Casey Maguire, PhD seeks to investigate novel AAV capsids and CRISPR/Cas9 gene editing as a gene therapeutic approach to target the XDP-SVA. Learn more about the ASGCT awards.
CCXDP Investigator Michael Talkowski, PhD Named Director of Center for Genomic Medicine at Mass General
September 1, 2020 – CCXDP investigator Dr. Michael Talkowski has been selected as Director of the Center for Genomic Medicine (CGM) at Massachusetts General Hospital. Dr. Talkowski will be the third CGM Director, following two world-class scientists, Dr. Sekar Kathiresan and founding director Dr. James Gusella.
Dr. Talkowski is a CGM faculty member, Associate Professor of Neurology with cross-appointments in Psychiatry and Pathology, and the Desmond and Ann Heathwood MGH Research Scholar. Within the CGM, he is affiliated with the Molecular Neurogenetics and Psychiatric and Neurodevelopmental Genetics Units, as well as the Mass General Analytical and Translational Genetics Unit, and directs the Mass General Genomics and Technology Core. He is also core faculty in the department of Neurology Collaborative Center for X-linked Dystonia-Parkinsonism (CCXDP), and an Institute Member of the Broad Institute of MIT and Harvard.
Michael completed his PhD in 2008 in Human Genetics, with a focus in neuropsychiatric genetics, from the University of Pittsburgh Graduate School of Public Health and Department of Psychiatry. His postdoctoral training followed in neurogenetics and genomics here at Mass General, Harvard Medical School, and the Broad Institute under Dr. Gusella. During this time, he developed methods to explore structural rearrangements in the genome and determine their impact in neurodevelopmental disorders and congenital anomalies. He was promoted to Instructor in Neurology in 2011 and appointed to the faculty as Assistant Professor in 2013.
Michael's pioneering research has defined changes in the structural organization of the genome and their implications for human disease. His discoveries have integrated molecular and analytic methods to traverse the continuum from identifying DNA mutations to exploring their biological mechanisms for translational insights. He initially used genome sequencing technologies to reveal the extraordinary complexity underlying chromosomal abnormalities in the human germline, including entirely new classes of complex genomic variation. He won the MGH Martin Prize in Translational Research for these discoveries, and the application of genome sequencing to prenatal diagnostics. His current research program is engaged in multiple consortia to explore the genetic architectures of common complex and rare Mendelian disorders, to create maps of structural variation across populations, to perform scalable functional perturbations of genes associated with disease, and to advance new technologies in prenatal and pediatric diagnostics.
