Additionally, Strahl also serves as the faculty director of the UNC High-Throughput Peptide Synthesis and Array Core Facility From 2016 to 2020, he served as the Vice Chair of the Department of Biochemistry & Biophysics at UNC. From 2020 to 2022, he stepped into the role of Interim Chair of Biochemistry and Biophysics. Since 2023, Strahl has held the position of Assistant Dean for Research in the Office of Research at the University of North Carolina School of Medicine. The primary mission of the Office of Research is to develop and implement a strategic plan for research in the School of Medicine(reference). The UNC School of Medicine selected Strahl as an

Investigator in recognition of his research contributions. This annual award recognizes senior faculty members who have gained international recognition for their work. Since 2015, Strahl has directed UNC's Program on Chromatin and Epigenetics, aiming to understand the complex language of epigenetic regulation. The program seeks to advance human health and address diseases. Stahl is also co-founder of EpiCypher, Inc. – a company known for services for chromatin biology and epigenetics research.


Research and Discoveries

Strahl is a pioneer in the field of
epigenetics In biology, epigenetics is the study of stable phenotypic changes (known as ''marks'') that do not involve alterations in the DNA sequence. The Greek prefix '' epi-'' ( "over, outside of, around") in ''epigenetics'' implies features that are " ...

). Strahl also helped to develop the first antibodies for methylated histones in the Allis laboratory. In 2000, Strahl and Allis put forward the idea of the “ histone code hypothesis”, which aimed to explain how multiple histone modifications function together to control chromatin structure and function. The early years of the Strahl laboratory, research focused on the roles of
