I pursue research with an interdisciplinary approach involving extensive field work, behavioural observations and laboratory experiments, and molecular and microbial ecology. I have worked in three international research groups in different countries, and published with more than 60 collaborators from all over the world. I have 14 peer-reviewed scientific papers, 43% of which are published in high impact Science and Nature group journals. Google Scholar metrics (last 5 years): 1000 citations, h-index 9, i10-index 9. I have two decades of experience carrying out behavioural research with a variety of fish and mammalian model systems, and have conducted expeditions in different environments, from subaquatic to terrestrial desert, in countries in Europe, Africa, and South America. Research carried out during my PhD with Prof. George Turner at Bangor University (Wales, UK), using the highly diverse East African cichlid fish as a model system for investigating evolutionary processes, resulted in three publications on population divergence and ecological adaptation (Tyers & Turner 2013; Tyers et al. 2014; Malinsky et al. 2015). During my first post-doctoral position I continued to work in the same group, contributing to several large interdisciplinary projects which have provided strong evidence for historically controversial, but now widely accepted, evolutionary mechanisms. For example, that continued and substantial gene-flow does not preclude the possibility of population divergence in sympatry (Malinsky et al. 2015, published in Science), and that hybridisation can contribute to, rather than restrict, adaptive radiation (Malinsky et al. 2018, published in Nature Ecology & Evolution). For these projects I carried out field work and laboratory experiments. Specifically, I tested within-individual consistency of mate choice, showing that in contrast to Lake Malawi cichlid species, diverging crater lake ecotypes are not reproductively isolated by direct mate choice. Using geometric morphometrics I showed that the current wide-spread riverine species with the proposed ancestral body type nest within the morphospace of recently diverged specialist lacustrine species found only within Lake Malawi. To expand my research toolkit I joined the group of Dr. Dario Valenzano at the Max Planck Institute for Biology of Ageing (Cologne, Germany), which uses annual killifish as a novel system for investigate ageing and lifespan from an evolutionary perspective, and the genomics of adaptation to extreme environments. In this role 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 researchers (e.g. Cui et al. 2021; Xu et al. 2023), assisted students with their projects, and organised 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. For the last year and a half I have worked as a researcher at BIOPOLIS (Vairão, Portugal), where, in collaboration with internal and external researchers, I have been developing rodent models to study composite phenotypic evolution in variable and extreme environments.
