One of my favorite and last shoots of 2015 was to photograph BioViva CEO Liz Parrish for @ozy and now my portrait of her appears on the cover of the Spanish science publication, QUO! Parrish was so interesting to get to know briefly. She is the head of a Seattle-based gene therapy research company and traveled to the country of Colombia to receive experimental stem cell transplants designed to reverse signs of aging. It was a controversial operation rebuked by some as unethical human experimentation. A colleague gave her only days to live several months ago, she admitted. Parrish, 44, said she believes that the issue of aging is too important for science to ignore.
