Colleen L. Hoffman
Postdoctoral Scholar, Geochemist, & amateur nature photographer
Hello! My name is Colleen and I am currently a Postdoctoral Scholar at the Cooperative Institute for Climate, Ocean, and Ecosystems Studies (CICOES, formally JISAO) and the University of Washington-School of Oceanography. My interests are investigating the cycling and transport mechanism of trace metals within hydrothermal systems to better understand their impact the deep sea and global geochemical cycles . I was a late bloomer in figuring out what I wanted to do when I grew up. It wasn't until I took an Oceanography summer course before senior year, as an undergraduate, that I became excited about the prospects of what I could do with my chemistry degree. Upon graduating from the University of Southern California, I worked for two years a technician in a deep-sea geomicrobiology lab. It was there I became increasingly interested in the role of trace metals, carbon, and their role in biological uptake and nutrient cycling in extreme marine environments. For my postdoc, I have been focusing on identifying and characterizing metal-binding organic ligands in different types of hydrothermal systems around the globe. This work built upon findings from my dissertation which found both organic and inorganic ligands are crucial mechanism for the transport and stabilization of particulate Fe across the ~4300 km Southern East Pacific Rise hydrothermal plume, the largest known hydrothermal plume.

Currently, about to head out on a 50-day research expedition hunting for low-temperature hydrothermal vents along the Southern East Pacific Rise. To find out where to follow along, click here
