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.
Nick McKay, Post Doctorate
I am a postdoctoral scholar working with Dr. Kaufman on synthesizing climate records of climatic and environmental change across the mid-Holocene transition from sites around the Arctic. I recently completed my Ph.D. in geosciences at the University of Arizona, where I primarily worked on a long lake record from tropical West Africa. I completed my undergraduate and Master's degree at Northern Arizona University, where I studied how climate signals are recorded in Arctic Lakes, and used lake records and gplacial landforms to reconstruct Holocene climate variability in southern Alaska.
I am Flagstaff native, and am happy to be back in town, along with my wife and our three young boys.
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 Alaksa.
Lab Manager, Katherine Cooper
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.
John Griffith, Geology
am a second-year Master’s student in the NAU Geology program. My research interests lie in multi-proxy
Holocene paleoclimate records preserved in lacustrine sediment. My current research focuses on reconstructing
climate variability in southern Alaska through a multi-proxy analysis of
sediment cores from Lake Tokun, lower Copper River, Alaska.
Taylor LaBrecque, Geology
I am a second year
Geology Master’s student at NAU. My research interests include recent
environmental and climatic changes preserved in lacustrine sediment. My current
project involves the reconstruction of the Holocene glacier history of Grewingk
Glacier in Kachemak Bay, Alaska, inferred from physical and biological
characteristics in pro-glacial lacustrine sediment cores from Emerald Lake.
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.
I received my bachelor's degree
in environmental geology from NAU in the spring of 2013. As I prepare to pursue
my master's degree studying fluvial geomorphology I assist in the Sedimentary
Records of Environmental Change Lab. My recent work includes correlating
surface cores from Shainin Lake in northern Alaska and helping to determine the
origins of the lake's sediment.
I am a third year undergraduate at NAU studying Environmental Geology, with a
minor in Chemistry. My current work focuses on Cascade Lake, in the
Brooks Range of Alaska, where I am using Biogenic Silica analysis as a proxy to
determine summertime temperatures.
I am currently an undergraduate in Environmental Sciences-
Biology at NAU. I work in the Sediment Lab and the Amino Acid Geochronology Lab
as a lab assistant processing geologic samples. I enjoy long walks on the beach
along with reading absorption on the spectrophotometer and tightening/loosening
caps on centrifuge tubes.
