Frederick (Rick) Colwell, Professor, College of Earth, Ocean, and Atmospheric Sciences, Oregon State University, Corvallis, OR

I was a research scientist at the Idaho National Laboratory for 20 years conducting basic research for the Department of Energy. In 2006, I joined CEOAS. I received my B.S. in Biology from Whitman College in 1977, my M.S. in Microbiology from Northern Arizona University in 1982 and my Ph.D. in Microbiology from Virginia Tech in 1986. Our research focus is on geomicrobiology, the microbiology of earth systems on the continents and in the oceans. In some cases we have studied microscopic life in shallow soils and watersheds but we’ve also investigated microbial communities that survive hundreds of meters underground. Our team examines the activities, diversity, and functions of microorganisms in these environments and I’ve led or participated in multiple scientific drilling expeditions on the continents and at sea. The classes I teach include Exploring the Deep (basic oceanography class), Astrobiology, and Cascadia Field Trip.

Jessica Buser-Young, PhD candidate (began summer of 2018)

My research focuses on defining the microbial diversity of the subsurface within glacial outwash ponds, and the role the microbes play in global element cycling. My aim is to strengthen our understanding of the link between iron redox processes and anaerobic oxidation of methane within freshwater sediments. In my free time I love to garden, bake bread, and paint birdhouses.
Kelly Shannon, MS student (began summer 2020)

I am a Masters student in microbiology and my area of interest is in microbial ecology. Specifically, I am intrigued by the connection between microbial biogeochemistry, ecosystem ecology, and climate. As a microbiology major my area of expertise is in bacterial dynamics, but I believe that the best way to study an environmental system is through a holistic and interdisciplinary approach.
