Professor Blum’s research group focuses on studies of geochemical controls on the structure and function of ecosystems, and on the application of trace element and isotope geochemistry across the Earth and Environmental Sciences. They utilize state-of-the art methods of chemical analysis and stable and radiogenic isotope measurement to address a wide variety of research problems from forest biogeochemistry and hydrogeochemistry to studies of fisheries and marine chemistry. Some student projects are fieldwork oriented and utilize relatively simple laboratory methods, whereas other projects involve the development of new laboratory procedures and methodologies.
