I am a sedimentary geochemist with expertise in radiochemistry – my research uses elements of the sedimentary record to answer questions about the functions, quality, and sustainability of sedimentary systems and host ecosystems, and about the history of those environments over the last ~10,000 years or more. This work often occurs at the interface of rapidly evolving natural and human processes considering both natural and built environments. This research has included lines of scientific inquiry within a range of subject areas including fluvial processes, coastal processes, neotectonics, marine sedimentary systems, carbon cycling, land use change impacts, limnogeology, and contaminant sourcing, transport, and fate. Characterization of various radionuclides (137Cs, 210Pb, 7Be, 226Ra, 228Ra, 234Th, 232Th, 230Th, 228Th, 239,240Pu, 14C) is a central tool of my research, as they often serve as tracers of physical, chemical, and biological processes, and as chronometers, allowing for specific proxies, events, or processes recorded in sedimentary archives to be dated precisely.
