I am an Assistant Professor in the Department of Educational Studies in the area of Applied Measurement and Research Methods at Purdue University. I also am Co-Director of the Purdue University Psychometric Instruction / Investigation Laboratory (PUPIL). I spend most of my time thinking about applied educational and psychological measurement issues (test score validity, test bias, etc.). My wife Sarah and I have two children, Elise (born 2004) and Evan (born 2006). In my free time I enjoy long distance running and cycling.
