Abstract: These are now exciting times in the field of evolutionary biology as rapid
technological advancements is allowing us to analyze genomes, transcriptomes, proteomes and diverse range of phenotypes in any species of interest relatively easily in a cost-effective manner. This provides us an unique opportunity to study adaptive evolution through the lens of modern 'omics. Motivated by this fact, my current work studies multiple vertebrate systems ranging from fish (Atlantic herring), reptiles (Squamates) and birds (Darwin’s finches & Ruff) and integrate genomic methods with the traditional knowledge about ecology and evolutionary history to reveal insights into adaptive traits that have amazed evolutionary biologists for decades. My work primarily focus on the interrelated avenues of (a) Parallel evolution of adaptive traits in geographically isolated populations (b) Genetic basis of adaptive radiation and rapid speciation (c) Impact of interspecies gene flow on trait evolution and hybrid speciation (d) Role of structural variants in adaptation and diversification (e) and understanding evolutionary processes underlying adaptive evolution at micro and macro evolutionary scales. My future work will build up on the groundwork of my current findings and ideally aim to set up a multi-disciplinary research program on “integrative genomics” that would bridge concepts and skills from several research areas and involve integrated analysis of multi-level ‘omics’ data, an approach that can contribute to providing mechanistic explanations for classical questions in evolutionary biology.
