Denis Agniel is an associate statistician at RAND. He is interested broadly in research questions that require multiple, possibly diverse measurements to accurately characterize complex outcomes like general health or complex disease like autism spectrum disorder. Agniel also has an active research interest in clinical informatics and large-scale analyses of claims data and electronic health records. Two of his recent informatics projects focus on opioid abuse in post-surgical patients and the use of doctor and patient behavior as encoded in electronic health records for the purposes of prediction. He has a long history of collaborative work with investigators in infectious diseases, HIV, autoimmune disease, and autism spectrum disorder. Agniel received his Ph.D. in biostatistics from the Harvard T.H. Chan School of Public Health and was a Postdoctoral Fellow in the Department of Biomedical Informatics at Harvard Medical School.
