• Pyrogenic and non-pyrogenic organic carbon interactions in the environment and implications for nutrient contaminant transport, climate change and carbon sequestration.

• Geologic carbon sequestration and geochemical implications for near surface environments.

• Development of innovative instrumentation and experimental approaches for investigating macroscopic and molecular scale geochemical processes occurring in complex environmental systems.

• Investigation and modeling of natural/engineered environmental systems in response to physical and geochemical perturbations.

• Geospatial/geostatistical modeling of physicochemical variables influencing hydrology or the fate and transport of contaminants/nutrients in terrestrial environments.

• Student conceptual models and development of teaching approaches/modules to enhance critical thinking and scientific practice in undergraduate science education.
