Susan Nolan turned to psychology after suffering a career-ending accident on her second workday as a bicycle messenger. A native of Boston, she graduated from the College of the Holy Cross and earned her Ph.D. in clinical psychology from Northwestern University. Her research involves experimental investigations of the role of gender in the interpersonal consequences of depression and studies of gender and mentoring in science and technology, funded in part by the National Science Foundation. Susan is the Associate Dean of Graduate Studies for the College of Arts and Sciences, as well as an Associate Professor of Psychology, at Seton Hall University in New Jersey. She has served as a statistical consultant to researchers at several universities, medical schools, corporations, and nongovernmental organizations. Recently, she advised Bosnian high school students conducting public opinion research.  Susan's academic schedule allows her to pursue one travel adventure per year, a tradition that she relishes. In recent years she rode her bicycle across the U.S. (despite her earlier crash), swapped apartments to live in Montreal, and explored the Adriatic coast in an intermittently roadworthy 1985 Volkswagen Scirocco. She wrote much of this book while spending a sabbatical year in rural Bosnia-Herzegovina, where her husband, Ivan Bojanic, worked as an advisor to regional governments. Susan and Ivan fell in love with Bosnia – a beautiful country – and bought a small house in the city of Banja Luka as a base for future adventures. They currently reside in New York City, where Susan roots feverishly, if quietly, for the Red Sox.
