Laboratory of Soil Ecology and Microbiology |
University of Rhode Island

Who are we?

People in the lab include professor Jose Amador, research and extension soil scientist George Loomis, graduate students Alissa CoxBianca Ross and Sara Wigginton, research assistant Kevin Hoyt, and undergraduate students Lauren Salisbury, Alicia Boucher and Jonathan Ludovico. The Lab started in 1994 as a collaboration between Jose and Josef Görres, now associate professor in the Dept. of Plant and Soil Science at the University of Vermont. We are housed in the Coastal Institute building on the Kingston campus of the University of Rhode Island.


What do we do?

Our research spans various aspects of the ecology and microbiology of soil, water, and
wastewater. We are interested in understanding the interplay among microorganisms, flora and fauna, and the physical environment, and how this affects the biogeochemical processes they carry out, as well as their fate. This knowledge can be used to address a variety of contemporary environmental problems, fromoptimizing soil-based wastewater treatment, to identifying the sources of bacterial contamination in surface waters, to improving soil quality and sustainable food production.

We are also interested in science education, including novel pedagogical approaches to teaching soil science, teacher training, and experiential education. The courses we teach include Introduction to Soil Science, Soil-Water Chemistry, Soil Microbiology, Senior Colloquium, and Microbial Ecology of Soils and Sediments.
