Juan is a Henslow Fellow based at the Department of Earth Sciences. Juan is interested in the evolutionary relationships between extant and fossil organisms and how ecological factors - including large-scale geological events such as mass extinctions - affected morphological evolution in deep time. His research-to-date focuses on reconstructing the origins of the anatomically modern bird body plan combining insights from living bird diversity together with key fossils  from  the earliest representatives of the extant bird lineage. Juan uses a combination of traditional and cutting-edge techniques, such as comparative anatomy, phylogenetic inference and high-resolution three-dimensional computed tomography to reconstruct morphological and ecological adaptations across the evolutionary history of modern birds, from their origins at the end of the Cretaceous period, through the mass extinction that decimated non-avian dinosaurs and the following explosive radiation into the ~11,000 living bird species inhabiting our planet today. Juan has a keen interest in scientific outreach and has published Birds of the Mesozoic, a field-guide style book with the aim of bringing the latest discoveries on bird origins and evolutions to a wider audience.

Juan obtained a Bachelor’s Degree in Biology at the University of Barcelona, and a Master’s Degree in Palaeontology at the Autonomous University of Barcelona. He then moved to the UK to work as a Research Assistant at the University of Birmingham, before pursuing a PhD at the University of Bath, focused on reconstructing the morphological transition separating modern-type birds from their closest extinct relatives. Juan is currently a UKRI-funded Postdoctoral Research Associate at the Department of Earth Sciences, and a Junior Research Fellow at Lucy Cavendish College.
