Postdoc & PhD – Diatom Paleoecology and Biogeography

Postdoctoral and PhD Positions in Diatom Paleoecology and Biogeography are available in the Department of Earth and Atmospheric Sciences, University of Nebraska – Lincoln, USA – both are part of large interdisciplinary projects:

1) PhD Position – Diatom Paleoecology and Yellowstone Lake Hydrothermal Systems

A position is available (August 2016) for a PhD student to participate in a NSF-funded interdisciplinary project to investigate hydrothermal systems in Yellowstone Lake across a range of temporal scales. The Nebraska PhD student, under the direction of Professor Sheri Fritz, will be involved in collection and diatom analysis of sediment cores that span the late-glacial and Holocene periods to evaluate the biotic response to past hydrothermal events. The student will have the opportunity to interact with a diverse group of collaborators, including colleagues investigating terrestrial ecosystems and geochemistry based on the cores, as well as individuals studying the contemporary hydrothermal systems in the lake and their sensitivity to tectonic, magmatic, and climatic variation ( Funding as a Research Assistant is available for 2 years. Interested candidates should submit a c.v. and letter of interest to Dr. Sheri Fritz (, as well as a formal application to the graduate college at UNL by January 15, 2016 for consideration. Applicants may have degrees in geology, biology, geography, or related natural science disciplines. Candidates must have prior experience in diatom analysis; students with a M.S. degree are preferred.

The Department of Earth and Atmospheric Sciences at the University of Nebraska – Lincoln has an active and diverse program in geosciences with strong research groups in paleoclimate, paleontology, sedimentology/stratigraphy, hydrology, and meteorology/climatology. For further information on the department and formal application procedures see the departmental web site

2) Postdoctoral Research Associate – Diatom Biogeography in Tropical South America

A postdoctoral research associate is sought to investigate the biogeography of diatoms in tropical South America. The individual will carry out diatom analyses of a large archive of samples from contemporary lakes across the continent to evaluate spatial patterns in a selected group(s) of taxa. The project can be tailored to suit the specific interests of the individual, and there is potential for augmenting the existing data set with new field collections. The position is part of a large NSF-funded project on the interaction of climate and geology in influencing patterns of biodiversity in tropical South America, and the individual will have the opportunity to interact with a diverse group of project scientists ( Applicants must have a Ph.D. in geology, biology, geography, or a related natural science discipline at the time of employment. Applicants must also have a strong background in diatom taxonomy and experience with GIS and/or spatial statistics. Funding, including salary and benefits, is available for up to 2 years. Starting date is negotiable, but review of applicants will begin 12/06/2015, and the position will remain open until filled. For further information on the position contact Dr. Sheri Fritz, Search Committee Chair, by email ( or phone (+1-402-472-6431). Information on the department is available at

To apply, go to Applicants must attach a cover letter, curriculum vitae, a statement of research experience and goals, and contact information for at least three references via the above website.
