Sedimentary Records of Environmental Change Lab Personnel


Lab Director, Darrell Kaufman 

I study geologic records of environmental changes, particularly those related to climate, that have shaped the Earth’s surface during the recent past and that operate on millennial time scales. 

David Fortin 

David Fortin, Post Doctorate 

After completing a PhD at Queen’s University, Kingston Ontario, and a postdoc at the Institut National de la Recherche Scientitique, Quebec city, I joined the lab as a postdoctoral scholar in the spring of 2013 through the University's Support for Post-doctoral Associates (SPA) Program. My work at NAU primarily focuses on the study of lake sediment records and on the monitoring of sediment fluxes in glacierized watersheds in Alaska.

Cody Routson 

Cody Routson, Post Doctorate 

I research, develop, and use natural climate archives to extend observational records, establish baseline conditions, and characterize the climate system and risks of climate-related natural hazards. My post-doctoral research is focused on Northern Hemisphere climate drivers, including Arctic weather patterns and sea ice fluctuation. Arctic sea-ice loss has major implications for both local and hemispheric climate. My work helps characterize the risk of extreme events and inform adaptation strategies to cope with climate change.

 Katherine Cooper Red Mountain 

Lab Manager, Katherine Whitacre 

I attained my Master’s degree in Environmental and Soil Science from the University of Tennessee, and currently manage both the Sedimentary Records of Environmental Change lab, and the Amino Acid Geochronology lab. I am interested in the study of amino acid racemization in foraminifera.

Graduate Students

Paul Zander 

Paul Zander, Environmental Science 

I am a graduate student in geology at NAU, and previously obtained a BS in environmental science from NAU. My research is focused on using biological and physical properties of lacustrine sediment to reconstruct environmental and climatic change in the Gulf of Alaska region. I am also using lake sediments to create a stratigraphy of volcanic ash deposits in the Copper River Delta region.

 Doug Steen  

Doug Steen, Geology 

I am a Master’s student in the Geology program at NAU.  My research interests include interpreting recent climatic and environmental changes from proxies within lacustrine sediment.  My current research focuses on developing a record of paleomagnetism and environmental magnetism for sediment cores from Cascade and Shainin lakes in the north-central Brooks Range of Alaska.

Research and Lab Assistants

Jai Beeman 
Jai Beeman, Post-Baccalaureate

I obtained a BA in Earth and Planetary Science from Harvard University, and after graduation held an internship in the Glaciology group of the Institut de recherche pour le developpement / Universidad Mayor de San Andrés in La Paz, Bolivia. I'm interested in glacier energy balance modeling and paleoclimate, and work on glacier change and lake sediments at NAU.

Monique Belanger 

Monique Belanger, Environmental Science and Policy Master's Student   

I am a graduate student in Environmental Science and Policy with an emphasis on Paleoenvironments. My research interests are using lacustrine sediments to evaluate Holocene climate change. My current research is focused on carbonate and pollen records from a small post-glacial lake in Snowmass, Colorado.
