Associate Professor
Graduate Coordinator

I am a chemical oceanographer with broad interests in the cycling of trace elements in the ocean. Trace elements are present in small quantities but exert tremendous influence on the capacity of the surface ocean to support life. For example, much of the primary production in the ocean is limited by the availability of the micronutrient iron. Much of the work done by members of my research group is focused on understanding how iron enters the marine environment.

I also serve as the Graduate Coordinator for the department. I am available to answer questions about our graduate degree programs and help prospective students navigate the application process


  • B.S. Lehigh Univeristy 2001
  • Ph.D. Florida State University 2008
Research Interests:

Aspects of environmental chemistry, chemical oceanography, and atmospheric chemistry including:
(1) The transport of biologically important elements to oceans and estuaries via aerosols 
(2) The processes controlling aerosol elemental solubility and metal speciation 
(3) The fate of aerosol derived trace elements and nutrients in aquatic and marine systems
(4) The distribution of dissolved and particulate trace metals in marine systems
