I took a personality test for the first time as a junior in high school, and have been hooked on personality psychology ever since. I received my A.B. in Psychology from Harvard University in 2000 and my Ph.D. in Social and Personality Psychology from the University of California, Berkeley in 2008. I arrived at Colby in the Spring of 2009. I’m excited to teach courses about personality psychology, research methods, and statistics, to work with motivated young researchers, and to explore Maine.

My research currently focuses on two key issues. The first is personality structure: How people’s specific thoughts, feelings, and behaviors cohere into broader personality characteristics that persist over time and across relevant situations. I am especially interested in questions about whether, how, and why people’s personalities might be organized differently at different times of life, or in different social contexts. For example, are personality characteristics organized in similar or different ways during childhood versus during adulthood?

The second issue is lifespan personality development: How people’s personalities change as they age, and how these changes relate with social (e.g., relationships, careers) and biological (e.g., health) factors. I am curious both about how people’s personalities typically change across the life course (normative change), and about why different people’s personalities change in different ways (individual differences in change).

I am also interested in a variety of methodological and quantitative issues. These include best practices for psychological measurement, using the Internet to collect psychological data, methods for modeling multidimensional structures, and methods for analyzing change.

Research Assistant

I am a Junior psychology major, with a human development minor. I am from Hingham, MA, and have been interested in psychology for most of my life, as both of my parents were psychology majors as well. I am particularly interested in child psychology as well as the psychological aspect of emotions, especially the more 'destructive' emotions.
