Tessa Harden Ph.D.

Assistant Professor of Science

Dr. Harden has a background in geology and paleoflood hydrology and has been employed by the U.S. Geological Survey and the Bureau of Reclamation since 2008 to research flood hazards throughout the United States. Harden’s research primarily focuses on quantifying extreme riverine floods in the last 10,000 years, reducing uncertainty in flood-frequency analyses of the very rare flood events, and investigating the link between climate and extreme floods. At Thomas College, Harden mainly teaches earth-science focused classes (geology, climate science, environmental science, etc.) with an emphasis on cross-discipline connections.
