Area of Interest
My research interests boil down to a single question: How can we most effectively use communication to change behavior and thereby improve the health of individuals and populations? This question turns out to be highly complex, and demands the careful study of message source, content, design, channel, and context. Answering this question requires the use of several methodologies, including qualitative methods such as interviews and focus groups and quantitative methods such as surveys and experiments. In efforts to cumulative knowledge in the field, I have also been a prolific user of meta-analysis, a quantitative research technique for synthesizing entire literatures on a given topic. My goal is to advance and build communication science, as well as to contribute to and shape public policy where it intersects with communication and health.
My work spans several topical areas of the health communication field. In the early days of my career I was focused on HIV/STD prevention, while now I mostly focus on cancer communication and prevention, especially tobacco prevention and control.
