Mark D. Shriver's research focuses on the evolution of traits such as skin color, hair texture, and facial features. These traits, which vary substantially across human populations, stand out as physiological systems that have changed rapidly over the past several thousand years. Dr. Shriver uses admixture mapping to localize the genes determining these traits, and population genomics to understand the evolutionary histories of the genes uncovered. Because many so-called "superficial" or "race" traits are clearly evident to observers, Dr. Shriver also investigates human perceptibility of (and preference for) particular traits -- how and why our species detects the alleles underlying phenotypic variability. Dr. Shriver also is working on admixture mapping for diseases (viz. T2D, PPROM, and IUGR), forensic molecular photofitting, genomic ancestry, short educational science videos, and personal genomics.
