Understanding environmental challenges requires scientific knowledge about the different spheres of the Earth -- land, water, air, and life -- and how they interact. Presents integrated perspectives across the fields of biology, chemistry, and earth and oceanographic science to examine the scientific basis for environmental change from the molecular to the global level. Foundational principles are developed to address major course themes, including climate change, energy, soil/air/water pollution, chemical exposure and risk, land use change, and biodiversity loss. Laboratory sessions consist of local field trips, laboratory experiments, group research, case study exercises, and discussions of current and classic scientific literature.
Dr. Vasudevan's research is concerned with the fate of synthetic and naturally occurring organic and inorganic compounds. Her work focuses on the mechanisms by which organic and inorganic compounds interact with mineral surfaces in soil and aquatic environments. Central research issues include the study of sorption, desorption and coordination chemistry; surface complexation theory; mineral precipitation, dissolution, and weathering; and surface-assisted chemical transformation processes. Dr. Vasudevan and her group use a combination of controlled laboratory experiments, molecular and surface complexation modeling, and statistical tools in their research. Completed and current projects have emphasized the study of iron oxide rich soils, and pure phase minerals (iron, aluminum and titanium oxides, silica, and kaolinite) and include:
