Tim Formosa, PhD, is a professor in the Department of Biochemistry at the University of Utah and a member of the Nuclear Control of Cell Growth and Differentiation Program at Huntsman Cancer Institute.Formosa studies how genetic material (DNA) is packaged and copied so that daughter cells each receive an accurate copy of the genetic instructions. Mistakes in this process are responsible for human cancers, but the machinery is common to many species. Formosa therefore uses single-celled yeasts to study the universal parts of the copying machinery because this allows the use of many experimental approaches that cannot be applied to larger animals, revealing the important principles that can then be tested in humans.Topics of study include--How histone chaperones participate in organizing and disassembling DNA packaging--How DNA is copied and assembled into chromatin, the stable form of DNA found in cells--How the packaging of DNA affects its accurate replication during cell divisionFormosa received a bachelor's degree from the University of California, Davis, and a PhD from the University of California, San Francisco.
