Jason Affourtit writes, “The encircling equation represents biologicalnitrogen fixation, which was at the core of my undergrad/graduate labwork. Working in that research lab (which was originally just part of requirements for med school!–my intended goal) totally changed my focus…So it’s an homage to that period of time, my wonderful advisor, and that lab. DNA has been central to my work life in genomics and has run through as a common theme. So to me, a G-C basepair seemed a natural symbol of that.”
