Overview
overview
Dr. Mattie's research focuses on the intersection between biostatistics, data science, and network science. Specifically, she has used network science and machine learning to study interactions in communities, as well as the development and application of artificial intelligence in healthcare research. Her research has also involved the notion of algorithmic fairness, in terms of an algorithm compounding inequities working against underrepresented or disadvantaged groups in society. Her work has found links between unhealthy weight control behaviors and the use of mobile dating applications, particularly in racial and ethnic minorities. She has developed methods that predict tie strength in a network, which assists in modeling the spread of disease and information. Additionally, her work has examined the potential for artificial intelligence to improve inference from data for care and population health, as well as the challenges related to bias and scalability in such models.

Dr. Mattie is involved in the diversity and inclusion efforts of the Biostatistics department and enjoys mentoring students.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
