Faculty Information


Dr. Stergachis is board certified in both Clinical Genetics as well as Internal Medicine. Dr. Stergachis’ research and clinical practice investigate how alterations in the human genome impact human health and disease. He received his BS in Biochemistry with honors from the University of Chicago, and joined the University of Washington Medical Scientists Training Program (MSTP) in 2007, where he completed his PhD in Genome Sciences. After graduating from the University of Washington Medical School, he completed a combined residency in Internal Medicine and Medical Genetics and Genomics at the Brigham and Women’s Hospital/Harvard Medical School. A Seattle native, Dr Stergachis returned to the Division of Medical Genetics at the University of Washington in 2020.

Research & Clinical Interests
Research Interests: 

Our group is motivated by the question of how alterations in gene regulation contribute to human disease. Genomics is rapidly emerging as a cornerstone of medicine, yet our current understanding of the human genome remains largely limited to only 1% of the genome, which is the portion that codes for proteins. By contrast, genetic changes in the other 99% of the human genome that alter when and where proteins are produced remain poorly understood. Our group aims to overcome this challenge by developing and applying novel epigenomic tools to study the impact of non-coding and epigenetic variation on human disease.

Clinical Interests: 

Dr. Stergachis sees patients in the UW Adult Genetics Clinic as well as the UW Cardiovascular Genetics Clinic, and has a broad clinical interest.
