Catherine Ball leads a group of population geneticists, statisticians, and computer scientists and oversees the analytical approaches behind Ancestry.com’s direct-to-consumer genotyping services. She is a genomic scientist who has annotated and mined the genomes of various organisms and created resources to help clinicians, citizens and other scientists exploit and explore genome data. Ball has collaborated on the annotation of the first sequenced eukaryotic genome (brewer’s yeast) and has collaboratively built databases to explore the genomes of yeast, E. coli and the bacterium that causes tuberculosis. As a pioneer in data analysis resources for high-throughput biomedical technologies, she led the Stanford Microarray Database, the largest academic database of its kind. She has used high-throughput biomedical data to shed light on diverse research topics, from the biology of infectious organisms to the mechanisms involved in cell division and cancer. She received a B.S. in Biology and a Ph.D. in Molecular Biology from the University of California, Los Angeles. Ball was a post-doctoral fellow at the University of California, Berkeley prior to her research in the Departments of Genetics and Biochemistry at Stanford University School of Medicine.
