PhD in Limnology: Modeling of Plant Plankton Succession in Lakes

Are you interested in the driving processes behind the plant planksonutsuit in lakes and you want to evaluate how plant plankis dynamics should change during future changes in the environment? Do you want an employer who invests in sustainable employee and offers safe, preferential working conditions? Welcome to seek employment as a doctoral student at Uppsala University, at the Department of Ecology and Genetics, within the Limnology Program.

The limnology program is an internationally recognized work environment with staff and students from all over the world. The program conducts research and education on biogeochemistry and economic inland water, from microscopic to a global scale. The program actively promotes a collegial and inclusive research culture through regular social activities, which encourages well-being, creativity and professional development.

Projektbeskrivning

Plant planks are an important basis for the nurement of the lakes and their composition is clearly changed during the year in response to physical and chemical changes, as well as predation pressure. These changes are in turn modulated by various functional properties between groups, which determine how they react to environmental conditions. With the help of models, we can study how environmental changes (such as climate heating, eutrophication and extremely weather) affect succession patterns in phytoplankton and identify conditions identify conditions that create favorable opportunities for specific functional groups. We can then use these models to assess possible future changes. We are looking for a motivated doctoral student who is keen to use process-based biogeochemical models to investigate this dynamics. The results of this work will improve our ability to forecast changes in phytoplankton communities, with direct application to the function of the sea ecosystems and drinking water supply. The service is based at Uppsala University's institution for ecology and genetics, within the Limnology program.

Tasks

Your duties will have a strong focus on data management and process-based, dynamic modeling, but also include teaching, course work and cooperation in research groups.

Kvalifikationskrav

To fulfill the eligibility requirements for doctoral studies, you must have:

• Departed degree at advanced level within limnology, aquatic ecology, environmental science, geoscience, biology, environmental technology or other relevant topics at the time of employment, or
• completed at least 240 High school credits, at least 60 High school credits at the advanced level including an independent work on the least 15 higher education credits, or
• In some other way, the corresponding knowledge is mainly acquired.

Candidates who have not yet taken out their degree but are expected to meet the requirements of access date can apply for the service

This work is in the intersection of physics, biogeochemistry and ecology and has a strong numerical component. Competent candidates need to show skills with advanced numerical methods (eg modeling, statistics or large-scale data analysis). Some programming experience (for example in R or Python) is required. Candidates must be able to express themselves very much in both oral and written English. In the evaluation of candidates, particular attention will be placed on personal qualities as independence, strong motivation and cooperation capacity.

Desirable / merit in general

• Previous experience with seafoods or other process-based models
• Familiarity with processes in lakes such as stratification and aquatic biogeochemical cycles
• Good understanding of phytoplankton ecology

Provisions for doctoral students can be found in the Higher Education Ordinance 5 Cape §§ 1-7 and in the university's rules and guidelines.
