Ecosystem and soil ecology, especially ecological rhythms and interactions of soil organisms and ecosystem processes.

I am also interested in the transport and transformation of carbon along the land-river-ocean continuum.

  Biol. 6995 - Biogeochemistry

During the last two decades, tropical environmental issues have attracted a great deal of scientific and public attention.  These issues include, for example, tropical deforestation linked with global warming, and land use changes associated with sustainability of plant primary productivity and maintenance of tropical biodiversity.  This course will introduce some of the fundamental biogeochemical principles which are used in studies of tropical ecological issues.  A strong theme of this class will examine how natural biogeochemical processes operate and how human activities can alter these processes.  The subject has been divided roughly into two parts: natural biogeochemical processes, and interactions between natural and anthropogenic processes.  In the first part, we will discuss biogeochemical processes occurring in atmosphere, land, and in ocean.  In the second part, we will use all that covered thus far to understand the anthropogenic effects on the cycling of carbon, nitrogen, phosphorus, cations, and sulfur and the implications to a variety of environmental issues.  Thus the course will analyze biogeochemical cycles from several different points of view, emphasizing an integrated approach.

Biol. 3111 - General Ecology

Teach the fundamentals of ecology to non-ecology majors. The course covers all aspects of ecology, from autoecology, developmental and behavioral ecology, through population and community ecology, ecosystems, biogeography and global change.
