Biography

Dr. Tom Ravens is a Professor in the Civil Engineering Department at UAA, and former Associate Dean of Research for the College of Engineering.  Currently, Tom’s research focuses on Arctic coastal hazards and risks including coastal erosion, flooding, permafrost thaw, and saltwater intrusion, as well as hydrokinetic renewable energy. Tom is PI of the Arctic Coastal Risk Network (ACRN), which is an NSF-funded Research Coordination Network (arcticcoastalrisk.net). The Network is a collaborative community of coastal researchers and practitioners from the natural and social sciences, which develops techniques to define, communicate, and mitigate Arctic coastal hazards and risks.
