Research Interests

I am an evolutionary biologist with a diverse background in molecular evolution, phylogenetics, morphometrics and genomics. My main study systems include members of the two biggest mammalian orders – bats and rodents – which are ideal for addressing a wide range of evolutionary questions regarding adaptive evolution. My research interests include studying convergent evolution (at both the morphological and molecular level) and specialisations of sensory systems. I am particularly interested in adopting integrated approaches that use multiple data sources to test hypotheses, and I enjoy learning new techniques in molecular biology as well as seeing my study species in the wild.

During my PhD I studied the origins of high-frequency hearing and echolocation in bats. This involved examining the molecular evolution of both protein-coding genes and non-coding regulatory elements (CNEs) associated with the functioning and/or development of the mammalian auditory system in bats. I also used µCT scans to study the minute structures of bat inner ears to look for adaptations relating to flight and echolocation.

I have continued to work on bats for my postdoctoral research. I am currently using comparative transcriptomics to study the molecular evolution of genes involved in the sensory systems of ecologically diverse Neotropical bats in collaboration with the Dávalos, Dumont and Sears labs. I have also performed genome-wide tests for adaptive evolution relating to underground life in African mole-rats, as well as other divergent lineages of subterranean mammals.
