I am a Marie Curie Fellow at the Biotechnical Faculty, Ljubljana University with Peter Trontelj and BGI Genomics. In this collaborative work I aim to understand how the olm (Proteus anguinus) has adapted to cave life. The olm is the largest obligate cave vertebrate, can live over a hundred years, regenerate its limbs, and looks really weird; these features have earned it a place in many nature documentaries. With the Proteus genome being sequenced and assembled, this will allow me to investigate the genetics of its evolutionary history and its many peculiar traits.
In general, my research focuses on how species and their traits have evolved over time. I am interested in the environmental and evolutionary drivers that trigger lineage diversification and trait transitions. Understanding why biodiversity arises is one important aspect, the other one being how it becomes established on the level of an organism’s genome. To answer the why’s and how’s of diversification and adaptation I use a combination of ecological, phylogenetic, population genetic and genomic tools in a statistical framework. To test the generality of evolutionary mechanisms, I use replicate systems and traits that evolved repeatedly in convergence.
It is an exciting time for studying the genomic architecture of complex phenotypic traits. The increasing accuracy of technological and methodological tools for analyzing vast amounts of genomic data provide unprecedented opportunities for unraveling the code of how phenotypes are created. This can even be possible for decoding phenotypic transitions that occurred in the deep evolutionary past millions of years ago. The foundation for such research is the collection of invaluable biological samples and data.
From an organismal perspective, I am a very keen on studying the evolution of amphibians and reptiles, focusing on an impressive set of adaptive traits that they evolved in convergence (such as viviparity, cave forms, sex determination, colouration, ecomorphology, etc.). I have also worked on different freshwater fishes to understand mechanisms of adaptive radiations.
