John Madsen

Associate Professor


I am the education coordinator and a governing scientist within the University's Center for Carbon-free Power Integration.  I have served as a Co-Chair of the University of Delaware Sustainability Task Force and I am a Past-President of the University Faculty Senate.

Undergraduate courses that I teach include: freshmen first year experience seminar; freshmen honors colloquia in energy and earth resources; introductory-level general geology; structural geology and plate tectonics; and senior seminar in petroleum geology and energy.  Graduate and upper-level undergraduate courses that I teach include: environmental and applied geology, geophysics, and geological aspects of offshore wind.

Current Projects

Sturgeon Research
With funding provided by NOAA, the National Marine Fisheries Service, and the Hudson River Foundation, we are using high-resolution side-scan sonar to image Atantic and short-nose sturgeon and their bottom habitats in the Delaware and Hudson Rivers.  The work is being conducted with Dr. Dewayne Fox and graduate student Amy Comer from Delaware State University.

Offshore Wind Research
With funding from the US Department of Energy and the National Science Foundation, we are examining how the geological and geotechnical setting of the Mid-Atlantic Bight, a portion of the US eastern continental shelf from off Long Island, NY to Virginia, can be used to place constraints on the siting of offshore wind projects.

Geothermal Research
With pilot funding provided by the University of Delaware Energy Institute's Innovative Energy Research Grants Program, we are exploring the feasibility and policy needs for transforming decommissioned offshore oil and gas platforms and retrofitting them for energy production as geothermal systems.
