Patrick O. Brown is CEO and founder of Impossible Foods, and co-founder of Lyrical Foods, Inc., maker of Kite Hill artisanal nut milk-based cheeses. After receiving his BA, MD and PhD (in Biochemistry) at the University of Chicago, Pat completed a residency in pediatrics at Chicago's Children's Memorial Hospital. As a fellow with Mike Bishop and Harold Varmus, he defined the mechanism by which HIV and other retroviruses incorporate their genes into the genomes of the cells they infect. As an HHMI Investigator and Biochemistry Professor at Stanford, Brown and colleagues developed DNA microarrays to monitor expression of all the genes in a genome and the first methods for analyzing, visualizing and interpreting global gene expression programs. Brown pioneered the use of gene expression patterns to classify cancers and improve prediction of their clinical course. He has been a leader in making scientific and medical research results freely available to scientists, physicians and the public. With Varmus and Michael Eisen, he founded “Public Library of Science”, a nonprofit scientific publisher that has transformed the publishing industry by making scientific and medical research results freely available to the public. Pat is a member of the National Academy of Sciences and the Institute of Medicine and recipient of the American Cancer Society Medal of Honor.
