Timothy brings over 30 years of experience in survey methodology.

Timothy is a senior fellow in the Methodology & Quantitative Social Sciences department. His work has focused primarily on sources of measurement and nonresponse error. Timothy has also invested considerable effort in examining the health behaviors of disadvantaged populations including homeless persons, immigrants, cultural minorities, criminal justice, and mental health populations.

Currently, Timothy is working on several analyses concerned with public attitudes towards the legitimacy of science in general and social science in particular. He is also working on analyses concerning sociological underpinnings of item nonresponse in social surveys as well as analyses concerning ethnic variability in acquiescent response styles. Timothy is also playing an active role leading a number of grant research projects.
