Kevin is a climate scientist, 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.

Talia Anderson
PhD student, Geography
M.A. 2020, Geography

Talia graduated from the University of Minnesota with a dual-degree in Geography and Spanish Studies. She specializes in the study of Latin American coupled socio-environmental mountain landscapes across different spatiotemporal scales and has developed and analyzed new Guatemalan tree-ring chronologies in order to study how climate change might impact forests in Central America. She continues to investigate the past, present, and future of climate change impacts on Central American forest systems. 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 the hydroclimate variability of wetlands in the Chilean Altiplano region using tree rings and remote sensing. For her Ph.D. research, Talia is investigating the socio-ecological impacts of climate change on water resources and agriculture in Latin America, supported by a grant from the US National Science Foundation as well as the Transect of the Americans Pathways Program.

Julie Edwards
Ph.D. student, Geography
M.S. 2020, Geography
Google Scholar: [Link]

Julie received her bachelor’s degree in Geography and 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 also a research assistant at UCLA and California State University, Northridge. Julie's research focuses on using high-resolution quantitative analysis of tree rings for climate reconstruction and to identify and interpret climate variability and extremes (including volcanic eruptions) in the paleoclimate record. Julie is a specialist in using Quantitative Wood Anatomy to understand seasonal and finer scale temperature signals in tree rings, and her dissertation research on high-resolution reconstructions of temperature variability at the North American treeline is supported by a grant from the US National Science Foundation.

Jonathan King
Ph.D. student, Geosciences
Google Scholar: [Link]

Jonathan received a B.S. in Chemistry with a minor in Applied Mathematics 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, evaluating the fidelity of climate models in reproducing important features of the climate system, and developing new quantitative methods for spatiotemporal data analysis and climate reconstruction. When not in the lab, he enjoys climbing and running in the Sonoran desert.

Kira Harris
Masters student, Geography

Kira received a B.S. in Earth Systems Sciences from the Ohio State University. Her previous research focused on how sedimentology and riverbed morphology affect surface water-groundwater interactions. She also helped develop Virtual Ice Explorer, a virtual field experience tool that allows people to explore remote polar and alpine field sites visited by researchers at the Byrd Polar and Climate Research Center. She is interested in multi-proxy paleoclimatology, organic geochemistry, dendroclimatology, and climate field reconstructions. Her thesis research will investigate variability and trends across multiple timescales (decadal to millennial) in the North American Monsoon over the length of the Holocene. Outside of research, she enjoys running, hiking, and learning about new plants and rocks.
