My research focuses on biogeochemical cycling of organic matter in modern and paleo-ecosystems using molecular and isotopic approaches. I am particularly interested in understanding interactions between human activities and natural cycles of organic matter. Past and current research projects include:
Understanding the effects of land uses on sources, composition and reactivity of aquatic organic matter
Reconstructing biogeochemical cycles of carbon and nitrogen in Lake Erie over its development and remediation of cultural eutrophication
Reconstruction of hydrological history over past 32k yrs in southwestern China using bulk and compound specific carbon isotopes of peat deposits
Developing micro-scale analytical methods for fish lipid analysis
