Beth Ann Sullivan is the James B. Duke Distinguished Professor of Molecular Genetics and Microbiology at Duke University School of Medicine, with additional appointments as Professor of Cell Biology and Associate Dean of Research Training. She has held these positions since 2023, 2022, and 2019 respectively, and is also a Member of the Duke Cancer Institute and Associate of the Duke Initiative for Science & Society. Her career at Duke has progressed from Visiting Assistant Professor (2005-2006) to Assistant Professor (2006-2013), Associate Professor (2013-2020), Professor (2020-2023), and now Distinguished Professor (2023-present).
Dr. Sullivan earned her Ph.D. from the University of Maryland, Baltimore in 1995. Her academic journey has been focused on understanding chromosome organization and function, particularly at the centromere.
Dr. Sullivan's research centers on chromosome organization with a specific emphasis on the genomics and epigenetics of centromeres. The centromere is a specialized chromosomal site critical for chromosome architecture and movement, and defects in centromere function are linked to cancer, birth defects, and infertility. Her lab has described a unique type of chromatin (CEN chromatin) that forms exclusively at the centromere through replacement of core histone H3 by the centromere-specific histone variant CENP-A. Her work explores how centromeres are specified, maintained, and how variation in centromeric DNA impacts chromosome stability.
Analysis of Dr. Sullivan's recent publications reveals a strong focus on centromere biology, particularly the genomic and epigenetic aspects of human and mouse centromeres. Her work has been instrumental in characterizing the complete genomic and epigenetic maps of human centromeres, contributing to the Telomere-to-Telomere consortium's efforts to assemble the complete human genome. Her research bridges molecular genetics, epigenetics, and chromosome biology, with implications for understanding genomic instability in disease.
Dr. Sullivan has received numerous scientific honors including:
- Gordon G. Hammes Faculty Teaching Award from Duke School of Medicine (2021)
- Fellow of the National American Association for the Advancement of Science (2015)
- Basil O'Connor Scholar from National March of Dimes (2003)
As Associate Dean of Research Training since 2019, Dr. Sullivan has been instrumental in shaping research training programs at Duke. She serves as Principal Investigator or Mentor on multiple significant grants including the Duke Preparing Research Scholars in Biomedical Sciences (PRIME) Cancer Research Program (awarded by NCI, 2023-2028), Duke Preparing Research Scholars in Biomedical Sciences Post-Baccalaureate Program (awarded by NIGMS, 2022-2027), and the Medical Scientist Training Program (awarded by NIGMS, 2022-2027). Her leadership extends to directing the Genetics and Genomics Cluster and co-directing the University Program in Genetics and Genomics.
Dr. Sullivan leads the Sullivan Lab, which focuses on chromosome organization and centromere biology. Her lab has made significant contributions to understanding centromere specification, CENP-A chromatin organization, and the implications of centromere variation for chromosome stability. The lab's work bridges basic chromosome biology with implications for human disease, particularly cancer and genetic disorders resulting from chromosome instability.
