I have been conducting research to better understand child and adolescent depression for the past 10 years. I have been on faculty at the University of Washington for the past eight years, and have been productive in conducting research on understanding risk for depression, testing etiological models, conducting meta-analytic reviews, and developing intervention curricula. I have developed a prevention program entitled "Positive Thoughts and Actions" to intervene with middle school students at risk for depression. This developmentally-based prevention program is unique and innovative in addressing key contextual factors that can make a big difference during the early adolescent years, including relationships with parents and family, school functioning, and health behavior. I am now actively testing the program, as well as a briefer intervention, in the Middle School Matters Study.
