Amy Pollack graduated from the New York City High School of Music and Art, then earned an B.F.A. from The Cooper Union, and a B.A. from Brandeis University with a major in Art History and with honors in Graphics. Her recent works include illustrations for publications of the Stevens Institute of Technology's College of Arts and Letters, illustrations for the Columbia University student magazine "Sanctum," and illustrations in "Crosscurrents" magazine. In addition to illustrating articles, she enjoys making soft sculptures, tee-shirt designs, collages and quilts. Her facility with scientific matters stems from summers spent at the Marine Biology Lab at Woods Hole Massachusetts, and on her work as a technician at Brandeis University, where she learned to make ribosomes from yeast. The Course of Nature is her first full-length book. An earlier version of The Course of Nature has been used as a reading in the Columbia College core course "Frontiers of Science," and in the Stevens Institute of Technology program in Arts and Letters.
