Gary Karpen

Gary Karpen is a Professor of Cell Biology in the Department of Molecular and Cell Biology at the University of California, Berkeley. His research focuses on understanding how nuclear organization, chromatin composition, and condensate and polymer biophysics impact genome and cellular functions, and organismal health. He utilizes interdisciplinary strategies that integrate cell biological, genomic, biophysical, and computational approaches to study these processes. His work often employs the fruit fly Drosophila melanogaster as a model system to investigate molecular mechanisms and their relevance to human cells and other organisms. Karpen's research has explored the biophysics of chromatin domains, DNA repair mechanisms, and the evolution of centromeres and heterochromatin.

Gary H. Karpen at UC Berkeley investigates heterochromatin, epigenetics, nuclear organization, and centromeres. His research explores the molecular mechanisms governing chromatin structure and function, with a focus on how heterochromatin domains form through phase separation. Karpen's work also examines the epigenetic regulation of centromeric chromatin, highlighting distinct histone modification patterns and their role in kinetochore formation. He has contributed to comprehensive chromatin landscape analyses in Drosophila and humans, emphasizing the importance of heterochromatin in genome stability and repeated DNA maintenance. His studies integrate genomic and epigenetic approaches to understand the dynamic interactions between chromatin and cellular processes.
