Michael P. Massagli, PhD (University of Wisconsin-Madison, Sociology, 1984) joined the PatientsLikeMe team in June 2007. I'm a sociologist and social statistician. My previous research has focused on survey methods and measurement of health outcomes and patient experience of care, looking, for example, at factors affecting the quality of survey data, employment experience and health-related quality of life of persons with AIDS, impact of trauma on mental health and physical functioning in refugee populations, and patient perceptions of health care quality.
