Nick has a lot of research interests, but they all are aimed at using natural records of past climate variability to inform our understanding of climate dynamics, or developing better ways to do so. We work on understanding natural climate variability in observations and models, in places ranging from the tropics to the Arctic, on timescales ranging years to millennia.

Cody Routson

Assistant Research Professor

Cody researches, develops, and uses natural climate archives to extend observational records, establish baseline conditions, and characterize the climate system and risks of climate-related natural hazards. His 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. Cody's work helps characterize the risk of extreme events and inform adaptation strategies to cope with climate change.

Michael Erb

Assistant Research Professor

Michael received his doctoral degree from Rutgers University, where he worked with Dr. Tony Broccoli to understand the response of climate feedbacks, equatorial Pacific seasonality, and wetlands to past changes in the earth’s orbit. Currently, Michael uses a data assimilation technique to leverage the strengths of general circulation model output and data from proxy records to better quantify climate variations over the past several millennia. His research interests include hydroclimate topics such as monsoons and drought, which affect people across the world.

Stephanie Arcusa

Ph.D. Student - Earth Sciences & Environmental Sustainability

Stephanie has a BSc in Earth Sciences from University College Cork, Ireland and a MSc in Climate Sciences from University Bern, Switzerland. Her current research interest lies in reconstructing drought and dustiness over the past 10,000 years for the Four Corners region of the U.S. southwest. She is also interested in making her research broadly useful to society.

Sela Patterson

M.S. Student - Geology

Sela has a BS in Geology-Environmental Sciences from Whitman College in Walla Walla, WA.

Ethan Yackulic

Ph.D. Student - Ecoinformatics (T3)

Ethan completed his M.S. in Environmental Science and Policy in December 2017, focused on reconstructing paleoclimatic conditions through analysis and interpretation of hyperspectral spectroscopy at Crater Lake in the San Juan Mountains of southern Colorado. In fall 2020 Ethan returned to the lab as a Ph.D. student in the informatics program, pursuing research on paleoclimate informatics and paleoproductivity in New Zealand.

Alumni

Chris Heiser

Alumnus (Application System Analyst)

Chris has a BSc in Computer Science from Northern Arizona University. He's interested in cyberinfrastructure for paleoclimatology, and helped to develop and improve the Linked PaleoData framework. Chris was the lead developer of LiPD utilities, and is part of the Linked Earth team. He's still involved in the LiPD project, but is also employed as a Software Engineer at Honeywell in North Phoenix, AZ.

Hannah Kolus

Alumnus (Research Assistant)

Hannah has a BSc in physics from Brown University and and MSc in Environmental Science from Northern Arizona University. Hannah worked as a research assistant in the PDL on abrupt climate change in the Holocene, and using process models to better understand glacier-hydrology-lake-sedimentation systems, and continues to contribute to research on these projects. Hannah works for the Rhodium Group in Oakland, CA.

Charlotte Wiman

Alumnus (Master's Student - Environmental Science & Policy)

Charlotte has a BS in Environmental Science from Northeastern University and completed her M.S. in Environmental Science and Policy in May 2019. Her thesis focused on varved sediments in Columbine Lake in Southern Colorado. Charlotte is currently pursuing her Ph.D. at Northeastern University in Boston, MA.
