I have some smart friends, you guys. Naomi asked me to be the photographer for her PhD ceremony last month in the aula of the Academy Building at the University of Groningen, which is always a spectacular setting to photograph. Prior to the defense, which lasts exactly an hour and during which no photos can be taken lest the clicking distract the candidate, Naomi and her paranymphs - her husband Tom and her friend and colleague Steffie - hung out in the "zweetkamer": the sweat room. Naomi defended her doctoral thesis - "On the nature and origin of self-esteem: A complex dynamic systems perspective of nested self-esteem phenomena" - with confidence and aplomb, and I always enjoy "photographing" PhD ceremonies because I get to learn about academic fields which are often unfamiliar to me. Her work was fascinating, comprehensible for non-experts like myself, and her doctorate was well deserved. Congratulations, Naomi!
