The PhD Programme in Biology is carried out in English, in a full-time, eight-semester system.
This PhD programme covers courses representing various areas of biological sciences, including training in modern methodology and mastering skills useful in professional academic and non-academic careers. Choice of facultative classes and the possibility of gaining credits for courses offered outside of the University ensures flexibility and helps to adjust participation in courses to the individual research plan of the student.
For everyone who will be accepted for the PhD programme in Biology, a scholarship is guaranteed.
PhD students are recruited for the specific research topics offered by the faculty members. Some of the competitions listed below are held outside the OAS system (Online Application System). We kindly ask you to follow the recruitment rules described in each competition.
Each year, PhD students and their advisors/promotors write an individual research plan for a given year. Until the end of four semesters, students’ achievements are evaluated (mid-term evaluation) by the committee.
Doctoral dissertations are prepared under the supervision of a scientific staff of the Faculty of Biology (members of the Institute of Botany, Institute of Environmental Sciences or Institute of Zoology and Biomedical Research). PhD programme in Biology leads to the scientific Doctoral title in the discipline of biology. More information about the programme can be found here.

Pursuant to § 7 sections 1 and 3 of Resolution No. 91/IX/2021 of the Senate of the Jagiellonian University of 29 September 2021 on the rules of recruitment for the Doctoral School of Exact and Natural Sciences at the Jagiellonian University in the academic year 2022/2023, the Director of the Doctoral School of Exact and Natural Sciences announces a competition for 1 doctoral student with a scholarship financed from the research project funds as part of the 4-year PhD programme in Biology.
Within the NCN-funded project entitled "The transcriptomic and metabolomic basis of heavy metal tolerance in Viola spp.", a commission set up at the School will conduct recruitment for the 4-year PhD study programme PhD programme in Biology.
The project manager,dr hab. Aneta Słomka, JU Prof., offers an opportunity to complete the doctorate in the following area: "The transcriptomic and metabolomic basis of heavy metal tolerance in Viola spp."
After the interviews and the evaluation of the candidates, the Chairman of the committee presents a report to the Director containing a list of candidates recommended for admission to the school as part of the research project.
The main aim of the proposed project is to identify the molecular and chemical mechanisms underlying tolerance to heavy metals in Viola spp. The project will focus on an example of heavy metal excluder – Viola tricolor represented by two genotypes: metallicolous (MET) – growing at polluted sites and non-metallicolous (NMET) – growing at non-polluted sites, both differing morphologically, genetically and in capability of accumulating heavy metals to indicate genotype dependent basis of tolerance to heavy metals. Violaceae family, including genus Viola (violets) is rich in metallophytes – species occurring in habitats with soils extremely polluted with heavy metals (e.g., serpentine, calamine, cupriferous or arsenic). These species must have developed the mechanisms which make them tolerant to the excess of heavy metals. Many of violets are metal excluders, which means that, in contrary to hyperacumulators, they prevent the translocation of heavy metals to the aerial parts of plant. While the molecular and chemical basis of tolerance mechanisms of hyperaccumulators are widely investigated, especially in species from the Brassicaceae family, little is known about non-model heavy metal excluders. Therefore, the following questions are raised: 1) what molecular mechanisms are engaged in exclusion of heavy metals (Zn and Pb) in violets, making them heavy metal tolerant? 2) what are the differences in gene expression level and profile between these two genotypes (MET vs NMET)? 3) do some chemical compounds (metabolites) produced by violets trap and detoxify heavy metals? 4) which tissues (especially of roots) are specifically involved in heavy metal binding and detoxification? We hypothesize that V. tricolor develops either universal (production of non-enzymatic antioxidants and protein heavy metal transporters), or specific to violets (e.g., cyclotides) mechanisms of tolerance to Zn and Pb, both unexplored so far. In particular, the following techniques and experimental systems will be used: (Task 1) treatment of plants with heavy metals (Zn and Pb in concentration ≤ 1000 ppm) under experimental conditions; (Task 2) measurement of heavy metal content in roots and leaves with atomic absorption spectrometry (AAS); (Task 3) RNA-seq transcriptome profiling for the determination of plant response to heavy metals at the gene expression level; (Task 4 - 6) application of different mass spectrometry and chromatography techniques (MALDI-MSI – matrix assisted laser desorption ionization mass spectrometry imaging; LC-MS – liquid chromatography mass spectrometry; LC-MS/MS – tandem MS) for metabolomic profiling and mining in response to heavy metals on the plant organ and tissue level, as well as for indication of compounds that bind and detoxify heavy metals.
