The FWO predoctoral fellowships aim to boost the professional development of young researchers who will help shape the knowledge and innovation of tomorrow. In this round, FWO awarded 310 fundamental research and 178 strategic basic research projects From ITM, three were approved, resulting in a 27.2 % (3 awardees, 11 submissions) success rate. All three awarded candidates are affiliated with both ITM and the University of Antwerp, carrying out their research mainly at ITM, starting on 1 November.

Habitat restoration, biodiversity recovery, and parasite community dynamics: linking theoretical models and empirical data

Olivia Toles, Unit of Virus Ecology, fundamental research project

Human-caused habitat damage and biodiversity loss are increasingly linked to the emergence of zoonotic diseases, but we don’t yet understand why. Restoring habitats is often seen as a solution, yet restoration doesn’t simply reverse degradation. It starts a new process of community assembly that changes which host species are present, how their life stages are structured, and how well habitats are connected, with uncertain effects on parasites and spillover risk.

This project examines how degradation and restoration reshape pathogen diversity. Using small mammal data from the Yangambi Biosphere Reserve in the Democratic Republic of the Congo, Olivia will measure parasite turnover and regional diversity along a restoration gradient and test whether parasites respond earlier and recover more slowly than their hosts. She will then build a model to show how restoration stage and habitat connectivity determine whether parasites persist, go extinct, or return.

Biological Adjudication of Post-Treatment Recurrence in Leprosy

Niels Vanden Bossche, Unit of Mycobacteriology, fundamental research project

Leprosy still occurs in more than 120 countries with around 200,000 new cases detected worldwide each year. Although leprosy is curable, there is still no reliable biological measure to confirm treatment success. Because Mycobacterium leprae cannot be cultured in vitro, bacterial elimination cannot be confirmed, and cure remains operationally defined. This makes it difficult to determine the underlying cause of recurrence: relapse, reinfection, or a delayed immune reaction.

To address this challenge, Niels will investigate a unique national cohort of recurrent leprosy cases from the Comoros, a highly endemic setting that he has already had the opportunity to visit.

His PhD project will combine next-generation sequencing approaches and RNA-based viability testing with clinical and epidemiological data to provide molecular evidence to support the classification of post-treatment recurrence. The findings generated during his PhD aim to strengthen treatment evaluation and resistance surveillance and support the development and assessment of new therapies.

Translating novel antigen combinations into next-generation Leishmania vaccines

Lies Mensch, Unit of Clinical Immunology, strategic basic research project

 Leishmaniasis causes up to one million new cases every year, yet there is still no human vaccine despite the high demand. A major hurdle has been not knowing which Leishmania antigens the body naturally processes and presents during an active Leishmania infection. This information is essential for designing T cell–focused vaccines. The Clinical Immunology Unit has now overcome this hurdle by creating the first patient-derived Leishmania immunopeptidome from patient skin lesions, and has identified several relevant antigens. The immunogenicity of these antigens will now be tested to determine which ones could be used to create a vaccine construct.

 This PhD project will develop next-generation self-amplifying RNA (saRNA) vaccine constructs, after optimising the Target Product Profile (the regulatory guidance document outlining the desired characteristics of a vaccine under development). The project will involve designing, formulating and testing saRNA vaccine construct candidates in mouse models, hopefully resulting in the first effective human Leishmania vaccine.
