Education and career

Barbeau graduated from Mercy High School in Middleton, Connecticut.[1] She has a B.S. from Southampton College (1991), and then moved to the Université libre de Bruxelles for one year.[2] She earned a Ph.D. from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution in 1998. Following her Ph.D. she was a postdoctoral researcher at the University of California, Santa Barbara until 2001 when she joined the faculty at Scripps Institution of Oceanography.[2]

Research

Barbeau is known for her work on trace metals, and how marine microorganisms interact with trace metals. Her early work examined how protozoan grazers relieve iron limitation in phytoplankton.[3] Through this research, Barbeau developed new analytical methods,[4] which she applied in the field.[5] Her subsequent research has examined photochemical interactions with metal compounds[6][7] and iron limitation in the California Current.[8][9] Her research has also investigated copper levels in the Pacific Ocean,[10] organic compounds that bind to metals in estuaries,[11][12] and the mechanisms used by bacteria to incorporate metals such as iron into the cell[13][14]

Katherine Barbeau continues to have her research interests lie in Biogeochemical cycling of trace metals in marine systems(focusing specifically on the Fe,Ni, and Cu metals), Biological transformations of trace metal speciation (the acquisition of trace metals), photochemical redox reactions of trace metals, and metals as limiting or co-limiting micronutrients in marine systems.[15]
