Music (especially jazz and progressive rock)
I have some professional musician friends, listed (alphabetically) below. Michiel Borstlap, Steve Hackett, and Patrick Moraz have written blurbs for the preface of my social psychology textbook with Roy Baumeister.
Traveling (especially in Europe)
I have taught courses, given lectures, and conducted research with colleagues in Belgium, France, Germany, Hungary, Italy, Luxembourg, The Netherlands, Poland, Poland, Romania, Spain, Switzerland, and the U.K. Each year I teach an intensive 1-week course on meta-analysis at the University of Luxembourg.
Vegetarian cuisine (eating and cooking)
I have been a vegetarian since age 18.
I love cycling, especially in The Netherlands. If the weather in Columbus is good, I also like to ride my bike to work at The Ohio State University (about 6 miles or 10 km). If the weather is bad, I like to ride a stationary bike at home.
