“I am an immunologist, and a second-generation biologist; my mother was a cell biologist (she passed away from brain cancer, which influenced my choice of career). I find DNA to be elegant; the code is so simple, and yet capable of enormous complexity. So I had my artist make a stylized DNA double-helix for me. The two double-stranded breaks don’t bother me; adaptive immune cells have those as part of normal development. 😉 “
