    We are seeking a motivated PhD candidate to join the project entitled:

    The effects of energy availability on pace of life and microbiome of bank voles from January 2023.

    Research topic:

    Acquiring energy from the environment is fundamental for the reproduction and survival of all organisms and animals have evolved many ways to gain energy. The community of microbes inhabiting the animal intestine (gut microbiota) has coevolved with animal hosts and participates in the critical task of extracting energy from food eaten by the animal (e.g. by producing different short-chained fatty acids). The microbiota can thus be especially important in matching the energy requirements of the animal with the resource availability in its environment. Coping with limited resources should depend on both the animal's metabolic demands and the efficiency of the gut microbes to extract energy from food. To test this idea, we study the effects of food manipulations at different life stages on the life history, physiology, and gut microbiome of animals from a unique experimental evolution model system: selection lines of a non-laboratory rodent, the bank vole (Myodes glareolus), selectively bred for a high metabolic rate and unselected control lines. The project is a part of a long-term research program off the Evolutionary Physiology Team, based on an artificial selection experiment (https:// www.

    The work scope:

    The experiments on animals in this specific project have been completed, and biological samples and data gathered during the experiments are available for analysing. The main task for this 12-month period of financing (the offered stipend) is to further process and analyze samples and data gathered during the experiments, and to prepare publications. Specifically, the work includes:

    - Characterizing the gut microbiota (bacterial communities) using sequencing data of the 16S-gene.

    - Body composition analyses.

    - Participating in short-chained fatty acid analyses.

    - Conducting bioinformatics and statistical analyses.

    - Preparing publications in close collaboration with the international team.

    - Possibly also presenting work at local and international conferences and participating in supplementary experiments on captive voles.

    The starting date is ideally 10 January 2023 or as soon as possible thereafter.


    Financial conditions: A National Science Centre stipend (4500 PLN/month gross) is available for one student for 1 year. The actual net payment depends on the student's status (applicable social insurance etc.). If the candidate is not yet enrolled as a student in the Jagiellonian University PhD School, we will encourage her/him to apply to the regular 4-year program starting from the next academic year (October 2023). PhD School enrollment is subject to open competition (and hence cannot be at this state warranted) and accepted candidates are eligible for a further stipend.

    Selection process

    Preliminary enquiries are welcomed by email to the principal investigator Anni Hämäläinen (, with a copy to the prospective PhD school supervisor, Paweł Koteja (

    The formal application should be sent by email to the above two addresses and to the appropriate Faculty secretary ( by 03.12.2022, and should include:

    1) A Curriculum Vitae (maximum 2 pages) including information on relevant academic achievements, publications, awards, and relevant experience and training. This document should also include identification information (PESEL number for candidates from Poland, or passport number for candidates from abroad).

    2) A motivation letter (maximum ca. 1 page), explaining how the applicant's background and research interests make them a suitable candidate for the position.

    3) A scan of MSc diploma, or a certificate informing that the degree has been already obtained, or a letter from supervisor confirming that the MSc thesis is completed and the defense or final exams are scheduled on or before 3.12.2022.

    4) Transcript of grades: diploma supplement, or the official transcript of grades, or another document listing completed courses and grades. Information about grading scale must be included.

    5) Two reference letters from recognized scientists who have first-hand knowledge of the applicant's skills and past research experience.

    6) Documents confirming the most important academic achievements declared in CV, particularly pdfs of publications.

    7) A signed copy of a formal statement concerning the processing of personal data, available here: https: // (or on request from PI).

    As a rule, the documents must be in English, with the exception of the copy of MSc diploma (#3), and the statement concerning personal data (#7), which can be in Polish. Diplomas and transcript of grades issued in other languages must be accompanied by certified translations to English or Polish.

    Additional comments

    The applications will be considered by the selection committee according to the regulations about scientific scholarships in research projects financed by the National Science Centre, Poland (https: // rady/2016/uchwala962016-zal1.pdf).

    Short-listed candidates will be invited for interviews and the decision of acceptance will be made by 16.12.2022. In case a suitable candidate is not found by this time, the enrollment procedure will be automatically prolonged.
