Training in the visual arts at Brown University and a lifelong interest in combining art and science led Tom to work first as an educator in science museums (Franklin Institute and Academy of Natural Sciences in Philadelphia), and then as a designer and construction coordinator of community-built science parks and playgrounds (Leathers and Associates, based in Ithaca, New York). In 1995, Tom founded Painted Universe, Inc., where projects included traveling exhibitions such as It’s a Nano World (with the Ithaca Science Center and Cornell University), The Enchanted Museum: Exploring the Science of Art (with the Berkshire Museum), and illustrations for The Elegant Universe by Brian Greene.
