Postdoc opportunities!

updated 12/7/2020

  • We are seeking a Postdoctoral Researcher in paleoclimate modeling and data-model comparison of the Earth’s tropical regions. The Postdoc will join a newly-funded collaborative effort to research the drivers of Central American paleoclimate on glacial/interglacial timescales using the isotope-enabled CESM and new 400 kyr records from Lake Petén Itzá, Guatemala (see NSF abstract here). Other possible projects include investigating moisture source variability to the Warm Pool, the Amazon, and central Africa during the Last Glacial Maximum using existing tagged water experiments with iCESM; and/or running new simulations to explore hydroclimate and isotopic variations in regions, or following processes, of your own interest. Experience working with climate model output is strongly preferred.This position is open to be filled immediately, but the start date is flexible. Spring or early Summer 2021 would be ideal. Work will take place remotely as long as COVID19 restrictions are in place. Partial remote work thereafter can be discussed.If you are interested, please contact Dr. Bronwen Konecky at bkonecky at wustl dot edu, and include your CV and a brief statement of your interests.
  • The Climate and Paleoclimate Lab is seeking a postdoc to work on triple oxygen isotopes in precipitation using a rich dataset of existing samples from East Africa collected by our group, plus opportunities for new sample collection and analysis. Start date flexible. If triple oxygen isotopes are your jam, please get in touch!
  • The Climate and Paleoclimate Lab is always seeking new postdocs, dependent on funding. Feel free to pitch your own idea! Get in touch with Professor Konecky at: bkonecky at wustl dot edu.

Ph.D. student opportunities

If you’re interested in tropical climate or paleoclimate, especially via biomarkers, light stable isotopes, and/or models, please get in touch with Professor Bronwen Konecky at: bkonecky at wustl dot edu. In your email, please describe your interests and background, and attach a resume or CV if you have one.

Potential project topics include the following, but feel free to pitch your own idea!

The modern tropical water cycle

  • Continental moisture recycling and African climate. How does moisture from the Congo rainforest contribute to rainfall variability and agricultural decision-making in western Uganda? How do the dynamics of seasonal wetlands influence land-atmosphere feedbacks in semi-arid Botswana? Current opportunities include water isotope, meteorological, and remote sensing observations in western Uganda as part of a newly funded initiative to understand rainfall variability and agricultural decision-making. This project is in partnership with physical and human geographers at the University of Colorado, University of New Hampshire, and Georgia State. More info here.

Ancient climates and environments

  • Modern calibration of leaf wax hydrogen isotopes and paleoclimate reconstruction. Can we quantify uncertainties (structural as well as parametric) on leaf wax hydrogen isotopes using a forward model embedded in a GCM? How much uncertainty is reduced when we add rich new measurements of modern tropical plants, soils, and waters? Current opportunities include greenhouse studies, model investigations, and paleoclimate reconstructions via lake sediments.

Earth system modeling and data synthesis

  • Synthesis of hydroclimate proxy records and comparison with isotope-enabled climate model simulations. What physical mechanisms of climate variability and change, explored using models, can explain observations in the geologic record? Current opportunities include analysis of existing/upcoming simulations of the Last Glacial Maximum and the past millennium, and data synthesis-model comparison of the past 2,000 years using the brand new Iso2k database.
