Research topic: Prediction of response to immunotherapy in melanoma using metabolic signatures of the gut mycobiome.
I. Project description
The main objective of the project is to develop novel, interpretable predictive models for response to immunotherapy in patients with advanced melanoma, based on the functional activity of gut fungi (mycobiota) and their metabolites. Current research indicates that the gut microbiome plays a significant role in modulating immune responses and the efficacy of cancer immunotherapies; however, most existing studies focus on bacteria and taxonomic descriptions, which offer limited predictive power and poor biological interpretability. This project focuses on the underexplored fungal component of the microbiome, which exhibits distinct metabolic capacities and the ability to interact with both the host immune system and bacterial communities. It is hypothesised that the functional and metabolic properties of the gut mycobiota, rather than its taxonomic composition alone, may represent a key determinant of response to immunotherapy. The analyses will be conducted on a cohort of patients with advanced melanoma treated with immune checkpoint inhibitors (anti-PD-1 therapy), using metagenomic, metabolomic, and clinical data. Integration of these datasets will enable the identification of metabolic pathways and metabolites associated with treatment efficacy, as well as the development of machine learning models with high predictive performance and strong biological interpretability. The ultimate aim of the project is to move from descriptive microbiome analyses towards a functional and mechanistic understanding of the role of the gut mycobiota in modulating anti-tumour immune responses, and to identify potential non-invasive biomarkers of immunotherapy response, which may contribute to the development of precision oncology.
Research shall be carried out within the 2025/59/D/NZ2/00484 NCN project entitled “Prediction of response to immunotherapy in melanoma using metabolic signatures of the gut mycobiome”, funded by National Science Centre.

*According to NCN requirements, only individuals who obtained a doctoral degree no earlier than 12 years before the year of employment in the project may be admitted. This period may be extended by the time spent on long-term (over 90 days) documented sickness benefits or rehabilitation benefits due to incapacity for work. Additionally, the period may be extended by the number of months spent on leave for the care and upbringing of children, as specified under the Labor Code. For women, this period may also be increased by 18 months for each born or adopted child if this method of accounting for breaks in the scientific career is more advantageous.
Furthermore, according to NCN requirements, individuals who obtained a doctoral degree at an institution other than the Institute of Bioorganic Chemistry of the Polish Academy of Sciences, or those who earned the degree at ICHB PAN but completed a continuous, documented postdoctoral internship of at least 9 months at an institution other than the project-implementing entity and in a country different from where the doctoral degree was obtained, may be admitted.
III. Duties in the project:
- Active involvement in the project, including planning and conducting multi-omics analyses (metagenomics, metabolomics, and immunophenotyping), as well as interpretation of results using bioinformatics and machine learning methods.
- Preparing summaries and reports.
- Continuously expanding knowledge in areas relevant to the project.
- Preparing scientific publications.
- Supervising the work of students and PhD students.
- Presenting results at seminars, scientific meetings, and conferences.
IV. Required documents:
- Application to the Director of IBCH PAN, containing contact details of previous scientific supervisors or other scientific employees who can give an opinion on the candidate.
- A copy of the diploma confirming the achievement of the doctoral degree.
- Scientific CV containing, among others, information on scientific, didactic and organizational achievements, including a list of scientific publications, information on management or participation in research projects.
V. Applications should be submitted via the eRecruiter portal at https://system.erecruiter.pl/FormTemplates/RecruitmentForm.aspx?WebID=724cac1d3715429ebc38ec8037f4f4f6
VI. Submission deadline is 2.11.2026.
Eligibility criteria
VII. After an initial verification based on the submitted documents, selected candidates will be invited to a job interview, during which the candidate recommended for employment will be chosen. The main criteria considered in the selection process will include: (i) scientific achievements (publications), (ii) relevance of previous experience to the research tasks planned within the project, and (iii) experience gained during research internships.
VIII. The recruitment procedure shall be concluded no later than 2.12.2026
