Biography

Carissa Tomas, PhD, is an assistant professor of epidemiology and social sciences and deputy director of the division of data surveillance and informatics in the Comprehensive Injury Center at the Medical College of Wisconsin. Dr. Tomas earned her PhD in neuroscience from the University of Wisconsin-Milwaukee. Though a neuroscientist by training, Dr. Tomas has extensive experience applying complex statistical approaches and machine learning techniques to “big-data” sources beyond the neurosciences. She has evaluated biological, neural, behavioral, and socioenvironmental domains to uncover the complex influences underlying mental health after traumatic injury. She uses cutting-edge statistical and data science applications with large-scale datasets from consortiums and databases to understand the complex dynamics of post-trauma outcomes. Dr. Tomas also serves as the statistical director for the MCW Public Health and Community PhD program.
