Huntsman Cancer Institute (HCI) investigator Katharine Ullman, PhD, is a professor in the Department of Oncological Sciences at the University of Utah School of Medicine, an adjunct professor in the Department of Biochemistry at the University of Utah, and a member and past leader of the Cell Response and Regulation Program. She served as the Associate Dean of the Graduate School at the University of Utah from 2016-2023.

Ullman and her research team focus on the coordination of cell division, with a particular interest in how disassembly and assembly of nuclear architecture is integrated with other events of cell division. The nucleus harbors a specialized environment, optimized to protect and regulate the cell's DNA. Mis-coordination of cellular remodeling during division leaves the DNA vulnerable to damage and mis-regulation. Elucidating this aspect of cell cycle control opens a new avenue to understanding cell function and how mistakes in division may contribute to tumorigenesis.

Ullman earned a PhD from Stanford University before going to the University of California at San Diego for her postdoctoral studies, which were funded in part by the American Cancer Society. She is a recipient of a Burroughs Wellcome Career Award in the Biomedical Sciences and a Scholar award from the Leukemia and Lymphoma Society. Ullman is an Allen Distinguished Investigator, a Paul G. Allen Frontiers Group advised program of the Paul G. Allen Family Foundation.
