I investigate mechanisms by which ecological and sexual selection contribute to biological diversification. My main fields of research are; evolutionary biology, ecology, and animal behaviour. I have 14 publications in scientific peer reviewed journals. Three are first author and the remaining, including a review, are from large interdisciplinary collaborations. 5-year impact factor of journals in which I have published: four papers IF >15, three papers IF 5-15, seven papers IF <5. Google Scholar metrics: 836 citations in the last 5 years, h-index 8, i10-index 7.. After completing my PhD on divergence and speciation of haplochromine cichlid fish with Prof. Turner at Bangor University, I continued as a postdoc for three years to develop recently discovered Tanzanian crater lake cichlid fish as a model system for sympatric (Malinsky et al. 2015; Munby et al. 2021; Vernaz et al. 2022), allopatric, and parallel speciation, through extensive field observations, behavioural and breeding experiments, and morphological analyses. During this time I also conducted work as part of the MolEcoFish project, surveying diversity and species distributions (e.g. Shechonge et al. 2019), and the Malawi cichlid genomes project (Malinsky et al. 2018; Vernaz et al. 2021). In my last position, alongside my research on life-history, behavioural, and microbiome divergence, I managed a laboratory at a Max Planck Institute in Germany which uses annual killifish to investigate ageing and lifespan from an evolutionary perspective, and the genomics of adaptation to extreme environments. I was responsible for overseeing the fish facility and wet laboratory, acting as a communication bridge between animal caretakers and researchers, training new staff and students, and representing the fish facility for the internal animal welfare body. I collaborated with other internal (e.g. Cui et al. 2021) and external (manuscripts in preparation) researchers, assisted students with their projects, and conducted field sampling expeditions. I gained further skills in molecular biology through microbiome sequencing projects, and advanced my skills in leadership and research group management. I have been invited to international scientific conferences and seminars to share new findings on cichlid diversity and the role of behaviour and ecology in speciation, and attended many other conferences to present my work to international audiences. I have co-organised three scientific events (conference/symposium and public outreach exhibition). I am currently working as an independent post-doc in the BioDeserts group at Universidade do Porto Centro de Investigação em Biodiversidade e Recursos Genéticos, investigating the evolution of pre- and post-zygotic reproductive isolation in recently diverged taxa, and co-evolution of phenotypic traits during ecological adaptation.
