Research Interests:

My scholarship activities unfold in two complementary directions. On the one hand, I try to assess the impacts that environmental perturbations have on biogeochemical cycling at ecosystem interfaces (coastal margins, lakes and flooded terrestrial zones, wetlands, urban atmospheres). On the other, I seek to address issues of scientific literacy in both a general social context as well as a specific one in the development of environmental curricula.
