Brem Lab

Rachel Brem, PhD

Understanding how and why traits differ between individuals and discovering genetic changes that impact aging behaviors.

Lab focus

Longevity, susceptibility to age-associated diseases, and many other attributes relevant for aging vary from one person to another. These differences are due in part to DNA sequence variants somewhere in our genomes, though exactly where is still a mystery in most cases. Worms, flies, and single-cell microbes can serve as powerful models for the study of the principles of genetic variation. Research in the Brem lab uses these model organisms to discover genetic changes that impact aging behaviors and other traits, as well as their evolutionary histories. The Brem lab approach uses large-scale analyses of thousands of genes at once, both computational and experimental.

Why it matters

Most genes contain instructions for the production of a protein — a molecular machine that does work for the cell — including information that regulates the amount and timing of protein production. The regulatory sequence included at the end of a gene is defined by a process called polyadenylation.
Solving the puzzle of why some people age better than others has implications for everyone. Genetic benefits that accrue to one person could be exploited to benefit all.

Dr. Brem is an associate professor and the faculty director of the Bioinformatics Core at the Buck Institute. She earned a PhD in biophysics from University of California, San Francisco, and did postdoctoral research at the Fred Hutchinson Cancer Research Center in Seattle, Washington. Before joining the Buck Institute, she held a faculty position at University of California, Berkeley, where she retains an adjunct appointment.

Dr. Brem is a geneticist and genomicist working at the interface between computation and experiment. She has been the recipient of a Burroughs-Wellcome Career Award, an Ellison New Scholar in Aging Award, and a Glenn Award for Research in Biological Mechanisms of Aging.
