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, 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, 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
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.
Rebecca Ellerbroek, Geology
I am a graduate student in NAU's geology program, where I am
using water isotopes to determine relative contributions of rain, snow, and glacial melt into an
Arctic lake system. I received my bachelor's degree in art and geology from
Cornell College in Iowa; my undergraduate research investigated ENSO effects on
monsoon precipitation using Australian speleothems.
Stacy Kish, Earth Sciences and Environmental Sustainability
I am a Doctoral
student in the School of Earth Sciences and Environmental Sustainability at
NAU. I received my Master’s degree from Oregon State University where I
examined ocean sediment to reconstruct climate in the eastern Equatorial
Pacific for the past 160 thousand years. My current research focuses on
developing the paleoclimate record from sediment obtained from Lake Peters,
located in the Brooks Range of Alaska.
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
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
Alec Soderberg, Post-Baccalaureate
attained my undergraduate degree in Geology from Northern Arizona University. I
am interested in Geochronology and Glaciology. Here at the lab I help prepare samples for amino
acid geochronology and biogenic silica analysis.
