Dr. Matthew Davis is a health services researcher who has additional training in data science.  He is an Associate Professor at the University of Michigan School of Nursing (Systems, Population, and Leadership) and the University of Michigan Medical School (Learning Health Sciences).  He received his Masters in Public Health from Dartmouth Medical School and his PhD in quantitative biomedical sciences from Dartmouth College.  His research focuses on leveraging large observational data to study policy-relevant issues, in particular the use of administrative claims data to perform US population-based studies.  Dr. Davis has made several important contributions to a variety of areas including the identification of dietary sources of arsenic exposure in the US population, the development of methods to use social media data to measure social support and public opinion, and the assessment of the risk of suicide among US healthcare workers.  Funded by the NIH, his current work is investigating variation in the identification of dementia as well as issues related to mortality among older adults living with dementia.  He serves as the research resources core lead of the University of Michigan’s Center to Accelerate Population Research in Alzheimer’s for which he oversees the development of analytic resources.
