Core Faculty

Silke Schmidt, PhDSilke Schmidt, PhD, is an Associate Professor in the Section of Medical Genetics, Department of Medicine. She currently directs a large-scale genetic-epidemiologic study of amyotrophic lateral sclerosis (ALS, Lou Gehrig’s disease) in US veterans, in collaboration with researchers at the Durham VA Medical Center. This study focuses on examining the role of gene-environment interaction in sporadic ALS. She is also interested in the evaluation and improvement of statistical methods for linkage and association analysis using simulated data, with an emphasis on methods to assess gene-environment interactions in complex late-onset disorders. In addition, she is involved in genetic studies of post-traumatic stress disorder in OIF/OEF veterans, glaucoma, age-related macular degeneration and rare thrombotic disorders. Dr. Schmidt was a CHG postdoctoral fellow from 1999-2001.

PhD, 1999, Department of Statistics, University of Dortmund, Germany
