Associate Professor
School of Geography and Development
ENR2 Building, Office S514

Kevin is a paleoclimatologist, dendrochronologist, and earth systems geographer specializing in the reconstruction and analysis of climate variability and change over the Common Era and the interaction between past climate and human society. He uses an array of techniques to develop and interpret evidence for past, present, and future climate dynamics across a range of temporal and spatial scales, from local to global and interannual to millennial. These include dendroclimatology, climate field reconstruction and spatiotemporal data analysis, stable isotopes, forward and numerical modeling of paleoclimate proxies, and the integration of paleoclimate data with General Circulation Modeling. He holds joint faculty appointments in Geosciences and the Laboratory of Tree-Ring Research, and is the chair of the Graduate Interdisciplinary Program in Global Change.

Bethany Coulthard
Ph.D., Geography
University of Victoria

Bethany specializes in the development and analysis of high-resolution paleoenvironmental (historical environmental) records, which she uses to interpret the impacts of climate change on earth’s hydroclimatology and forest vegetation. A principal goal of her work is to design studies that generate useful information for water, forest, and other resource managers, and policy-makers addressing climate change.

Bethany’s postdoctoral research uses tree-ring data to explore long-term interactions among precipitation, streamflow, drought, and forest primary productivity in the Mediterranean and in western North America. Her work is supported by grants from the United State Geological Survey and the US National Science Foundation. Her research program includes assessing the unusualness of recent snowpack declines, streamflow drought, and glacier ice melt in the western United States and Canada; developing new methods for paleohydrology in complex river basins; assessing the impact of snowpack declines on forest vegetation in the Canadian Coast Mountains; and evaluating hazardous mass movement events related to climate change in the Canadian cordilleras. You can follow her on Twitter @BLCoulthard.

Bethany starts a new tenure-track faculty position at the University of Nevada Las Vegas in January 2019!

Jessie Pearl
Ph.D. student, Geosciences

Jessie received her B.S. in Geology from Tufts University with a double major in Environmental Studies. She was awarded the George Melendez Wright Climate Change Youth Initiative Scholarship and worked with the Nature Bridge initiative at the Santa Monica Mountains National Recreation Area prior to coming to the University of Arizona. Jessie's research uses Atlantic White Cedar trees from the northeastern United States to reconstruct past climate variability, sea level rise, and storm events. Jessie is a University of Arizona Carson Scholar and a Philanthropic Educational Organization Scholar. You can follow her on Twitter @swampmonstah.

Gloria Jimenez
Ph.D. student, Geosciences

Gloria is jointly advised by Kevin Anchukaitis and Julie Cole, and focuses on how the Pacific Ocean and El Niño will respond to climate change. Her projects include using corals from the Galápagos Islands to reconstruct the recent history of the Eastern Pacific Ocean and determining ENSO states via classification techniques. Gloria is committed to linking climate change research with real world problems and communicating science outside academia, including publishing non-scientific work. She is a returned Peace Corps Volunteer who served in Ecuador and holds a B.A. from Carleton College and an M.S. from the University of New Mexico. She is also a National Science Foundation Graduate Research Fellow, a Philanthropic Educational Organization Scholar, and a UA Carson Scholar. When she takes off her scientist hat, Gloria enjoys collecting athletic hobbies and recipes.

Talia Anderson
M.S. student, Geography

Talia graduated from the University of Minnesota with a dual-degree in Geography and Spanish Studies. She is interested in studying tropical landscapes at different spatio-temporal scales and has developed and analyzed new Guatemalan tree-ring chronologies in order to study how climate change might impact forests in Central America. Before moving to Arizona, she worked for the TRACE (Tropical Responses to Altered Climate Experiment) project, a forest warming experiment in Puerto Rico. For her master's research, Talia was awarded a Fulbright Scholarship to study hydroclimate variability of wetlands in the Chilean Altiplano region using tree rings and remote sensing.

Julie Edwards
M.S. student, Geography

Julie received her bachelor’s degree in Geography/Environmental Studies from UCLA. She then worked as a GIS technician at an international aid and development nonprofit. Before coming to the University of Arizona, Julie was a research assistant at UCLA and California State University, Northridge. Her master’s research will focus on paleoclimate reconstructions and climate model comparisons

Jonathan King
Ph.D. student, Geosciences

Jonathan received a B.S. in Chemistry from Dartmouth College. He then worked with the USGS before earning his Masters in Geoscience from the University of Arizona. Jonathan is interested in assimilating paleoclimate proxies with climate model simulations over the Holocene. When not in the lab, he enjoys climbing and running in the Sonoran desert.
