I am an evolutionary biologist, with a diverse background in phylogenetics, molecular evolution and palaeontology. Throughout my research, I have adopted a multidisciplinary approach and am particularly interested in holistic studies that can combine multiple data sources, such as molecular and morphological trait evolution, to test hypothesis and answer evolutionary questions. I am interested in studying convergent evolution at the morphological and molecular level, and using approaches that integrate molecular and morphological information.
I pursued many of these research interests during my NERC funded PhD ‘A comparative study of the evolution of mammalian high-frequency hearing and echolocation’, which focused on determining the origins of echolocation in bats by undertaking a multidisciplinary evolutionary study. My PhD’s primary focus was assessing the molecular evolution of genes involved in mammalian hearing in bats. I also examined the substitution rates of specific non-coding regulatory elements (CNEs) extracted from ~40 mammalian genomes, putatively associated with the development of the auditory system. Finally, as mammalian inner ear development is controlled by many genes, I studied the gross structure of the bony labyrinth in order to examine the combined genetic effect.
Recently, I have become interested in NGS data analysis and I am currently employed as a postdoctoral research assistant responsible for the assembly, annotation and analysis of mammalian transcriptome datasets to answer a variety of evolutionary questions.
