C. David Allis

C. David Allis is a prominent American biochemist known for his groundbreaking research in the field of epigenetics. He studies how chemical modifications to DNA and histones—the proteins around which DNA is wrapped—affect gene expression without altering the genetic code itself. His work has significantly advanced our understanding of how genes are regulated and can influence various biological processes, including development and diseases like cancer. Allis's contributions have increased awareness of how environmental factors can impact gene behavior, thus linking genetics and health to lifestyle and external conditions.
