Randie Bundy is an assistant professor in the School of Oceanography at the University of Washington. Her research focuses on understanding the cycling of trace metals in the marine environment, with a focus on metals that are necessary for life. Specifically, she is interested in how the chemical speciation of trace elements impacts their uptake and recycling by phytoplankton and bacteria, and how microorganisms have adapted strategies for dealing with the insufficient concentrations of these essential nutrients present in the ocean. Many metals, such as iron, copper, cobalt and nickel, are essential components of key enzymes and proteins used for important metabolic processes in the ocean, such as carbon fixation and nitrogen assimilation. However, they are very scarce in the ocean and are often present in concentrations 10-100 times less than what is required for microbial growth. Bundy’s research involves exploring microbial metal uptake and recycling in a variety of oceanic environments, ranging from the oligotrophic gyre of the North Pacific to the polar waters of the Arctic and Antarctic. Bundy received her B.S. in 2008 from the University of California at San Diego and her Ph.D. from Scripps Institution of Oceanography at UCSD in 2014. During her Ph.D. she worked on determining the sources and sinks of iron and copper-binding organic compounds in coastal waters, and elucidating their impact on trace metal bioavailability. Then, from 2014 to 2017, she worked as a postdoctoral research scholar at Woods Hole Oceanographic Institution studying the cycling of cobalt in the Arctic Ocean and isolating siderophores and other metal-binding organic compounds from seawater and determining their impact on phytoplankton growth.
