Dr. Tucker's work focuses on geomorphology and landscape evolution. He uses numerical modeling, field observations, in-situ field monitoring, digital elevation data analysis, and other techniques to improve our understanding of processes that shape the earth. He also works in designing, developing, and testing software for computer simulation and coupled modeling of earth-surface processes, including hydrology, sediment transport, and landscape evolution. His research includes work on present-day geological hazards such as debris flows, floods, and gully network growth, as well as research into the long-term formation of landscapes and sedimentary basins. Since 2017, he has served as Executive Director of the Community Surface Dynamics Modeling System (CSDMS).
GEOL 3820 - The Fluid Earth
Fall 2018 / Fall 2019
Examines the myriad forms of fluid behavior found on Earth, from the atmosphere to the inner core. Explores how basic principles of fluid physics may be used to understand a broad range of earth processes, including mantle convection, atmosphere and ocean dynamics, stream flow, lava spreading, and glacier motion, among others. Covers fundamental fluid concepts such as viscosity, pressure, convection, friction, and free-surface flow. Department enforced prerequisites: MATH 1300 or APPM 1340 and APPM 1345 or APPM 1350. Recommended prerequisites: Any 1000 level GEOL class and PHYS 1110.
GEOL 5700 - Geological Topics Seminar
Spring 2018 / Spring 2019
Offers seminar studies in geological subjects of special current interest. Primarily for graduate students, as departmental staff and facilities permit. May be repeated up to 15 total credit hours provided that topics vary.
GEOL 5702 - Geomorphology Seminar
Spring 2018 / Fall 2018 / Spring 2019 / Fall 2019 / Spring 2020

GEOL 5775 - Introduction to Numerical Modeling in Geoscience
Numerical models play an essential role across the geosciences, with applications that include hypothesis exploration, data interpretation, and prediction. This course provides a hands-on introduction to numerical modeling. Students learn scientific programming and modeling concepts by iterating through a series of model-development assignments in Python and Matlab. Applications span a range of topics in the geosciences, with emphasis on physical processes that involve mass, energy, and/or momentum transport.
