Emeriti Faculty

Research interests include pedology, soil geomorphology, soil geochemistry, quaternary geology, organic and mineral fluxes during soil, atmosphere, water and vegetation interaction.

I specialize in the analysis of problems defined over space and time, including logistics and transportation, location theory, water resource systems, and urban and environmental systems using and developing new techniques in Operations Research, GIS, Decision Theory, and Heuristics.

Cartography and Geographical Information Science.

My current research focus is evaluating the potential for diet change and local food systems for solving the health, environmental/climate, and equity crises.

I work in urban and regional modeling and planning, spatial cognition, geographic information science, geography of the information society.

Interdisciplinary ocean research topics have included: bio-optics, biogeochemistry, hurricanes, ocean eddies, and monsoons plus medical research concerning the use of scent detection dogs for COVID-19 screening.

Jeff studies optical properties of snow. He helped animate Disney’s Frozen, his only Oscar (2014 Best Animated Feature).

Research areas are Global Climate Change Science and Education.

Although I am no longer involved in active research I continue to follow progress in geographic information science.

Time-geography of cities, the role of space-adjusting technologies in structuring new patterns of social and economic organization, and locational conflict analysis.

Geographic Information Science, usability, semantics of spatial information, ontology of the environment, linked data, semantic reference systems.

Climate-related components of food-security in developing nations through the lens of geography.

Remote sensing of oceans, biological oceanography, primary production and bio-optical modeling with emphasis on Antarctic ecosystems.

Individual and aggregate decision making, and the application of methods of artificial intelligence models to such problems.

The Washburn lab uses robotic vehicles, HF radar, satellites, and other approaches to study the coastal ocean and its ecosystems.
