We're particularly interested in welcoming new students, visiting scientists, and postdocs with an interest in one or more of the following:

  • Large-scale quantitative reconstructions of past temperature and hydroclimate using tree-rings or other proxies
  • Paleoclimate data assimilation and other advanced statistical techniques
  • Building new tree-ring chronologies for reconstructions of temperature, precipitation, drought, and other climate metrics over the Common Era
  • Quantitative wood anatomy for applications in climate or ecology
  • Research integrating climate data and paleoclimate reconstructions with historical, archaeological, and modern social science data to better understand the interactions and feedbacks between coupled human and natural systems in the past, present, and future
  • Tropical dendrochronology and recent climate variability, particularly in Central America and throughout the Neotropics
  • Quantitative climate model comparisons or assimilations with paleoclimate data and reconstructions for better understanding climate dynamics and for evaluating models
  • Proxy systems modeling
  • Stable and radiogenic isotope dendrochronology, particularly focused on reconstructing ocean-atmospheric circulation, tropical climate variability, or providing precise chronology for important events in Earth's history
  • Paleoclimate dynamics using the combined power of paleoclimate proxies and models, including the connection between climate and ecological processes (productivity, fire, forest dynamics), understanding large-scale modes of climate variability, and using networks of proxies to understand past ocean-atmosphere variability.

Potential graduate students and postdoctoral scientists are encouraged to contact current and previous members of the lab to gain an independent perspective on academic life at the University of Arizona, living in Tucson and the southwest, and the style and history of mentorship and training in our lab.

Postdoctoral Scholar and Fellow Opportunities

If you are interested in preparing NOAA, NSF, NASA, or other postdoctoral fellowship applications to come to the University of Arizona, please contact me to discuss options. Our lab welcomes postdoctoral scientists broadly interested in working on research questions related to past, present, and future climate and environments as well as coupled natural-human systems and the dynamics of socio-environmental systems.

Our lab's NOAA Climate & Global Change Postdoctoral Program host description is here. The deadline is typically very early in January every year. Unlike the NSF opportunities below, the NOAA program is open to non-US citizens and non-permanent residents on a visa.

If you have a Ph.D. in Geography (or anticipate completing your Ph.D. in the coming year) and you are a US citizen or permanent resident (a 'green card' holder), you may want to consider the Postdoctoral Fellowship Program at NSF SBE. The deadline is typically in November. Please contact me if you're interested in submitting a proposal to join our lab and the School of Geography, Development, and Environment as a Postdoctoral Fellow. Note there are two possible tracks for SBE Postdoctoral Fellows: Fundamental Research in the SBE Sciences (SPRF-FR) or Broadening Participation in the SBE Sciences (SPRF-BP).

If you have a Ph.D. in the Earth, Ocean, Atmospheric, or Environmental Sciences (and you are a US citizen or permanent resident),you may want to consider the Postdoctoral Fellowship Program from NSF AGS (which has a rolling deadline) or the Postdoctoral Fellowship Program from NSF EAR (which has a September deadline).

Postdoctoral Fellowships are also now available through a new call from NSF's Office of Polar Programs. The deadline is each February. If you'd like to join us to do work at high-latitude treelines or Arctic ecosystems, please consider this program and get in touch. As with other NSF postdoctoral programs, you need to be US citizen or permanent resident at the time of the application.


The Laboratory of Tree-Ring Research has the Agnese N. Haury Visiting Scholar & Trainee Fellowship, which provides limited funding to support visitors to the LTRR for several weeks to learn new skills in dendrochronology and collaborate with LTRR investigators. In those years when the program is offered and there is sufficient funding, the deadline for applications is typically in the late spring. Scientists and students interested in visiting the LTRR on a Haury Fellowship to my lab should contact me in advance of the deadline to discuss ideas and the application process.

Graduate Student Opportunities

I do not plan to admit any new graduate students in 2023. However, my colleagues Diego Pons and Matthew Taylor at the University of Denver have exciting funded Research Assistantships open this year as part of a new project in Guatemala (on which I am a collaborator): http://portfolio.du.edu/M.J.Taylor/page/130407

Students in my lab work in a range of research areas including multiproxy dendrochronology, spatiotemporal data analysis and data assimilation, coupled human-natural systems and the connection between climate change and human society, and paleoclimatology across a range of timescales and different proxy systems around the world. What is most important is not the tools we use per se, but rather the questions we ask and the impacts they have for society.

I encourage you to get in touch with me via email to discuss current openings. In your email, please be sure to describe how your previous background and future interests aligns specifically with those of my laboratory. Potential Masters and Ph.D. students interested in coming to the University of Arizona for dendrochronology, paleoclimatology (especially high resolution paleoclimatology), earth systems geography, proxy system modeling, climate field reconstructions, climate model/data intercomparisons, and/or radiocarbon are encouraged to contact me [] about potential opportunities.

Graduate school application deadlines are in earliest January of each year for autumn admissions. I mentor and advise students in Geography, as well as the Laboratory of Tree-Ring Research. More information on the graduate program (including admissions requirements and deadlines) in Geography is available here (Masters) and here (PhD). I am no longer accepting new students through Geosciences.

Graduate students may also wish to consider simultaneously applying to the American Meteorological Society Graduate Fellowship program (only available to 1st year graduate students) and the US National Science Foundation's Graduate Research Fellowship Program (available to 1st or 2nd year graduate students only, so applying early may help increase your opportunities). Other relevant graduate fellowships include the DOE's Computational Science Graduate Fellowship, the US Department of Defense National Defense Science and Engineering Graduate Fellowship, and NASA's Future Investigators in Earth and Space Science and Technology
