Interests and Expertise

  • Investigating the processes of organic matter cycling throughout watersheds — from soils to rivers to estuaries.
  • Elucidating the interplay between degradation and sorption processes in determining the composition and ultimate fate of organic matter within river systems.
  • Employing diverse analytical and experimental techniques to answer hypothesis-driven questions.
  • Synthesizing observation and theory into quantitative models of various types in order to guide new experiments and theory.
