Dr Stephen Noell

Qualifications: BSc Geneva College, PhD Oregon State University

I was born and raised in the US, earning my Bachelor of Sciences in Biology with a concentration in Cellular and Molecular Biology from Geneva College in Beaver Falls, Pennsylvania. I then completed my PhD in the interdisciplinary Molecular & Cellular Biology program at Oregon State University, working in the lab of Dr. Stephen Giovannoni. My PhD research focused on the physiology and metabolism of the most abundant group of bacteria in the world, SAR11, a marine, heterotrophic group of alpha-proteobacteria. During my research, I worked with these challenging microbes in culture to better understand why they are so abundant despite having one of the smallest genomes of any free-living microbe. I currently work as a Postdoctoral Fellow at the Thermophile Research Unit under Dr. Craig Cary. Our Marsden Fund project centers around the culturing of novel thermophiles from geothermally active subsurface environments, especially the subsurface of Mt. Erebus in Antarctica. My interests are in the use of novel culturing techniques to bring understudied microbes from the environment into the lab, to better link physiology to environmental function.
