Dr Ian Brennan

Ian is a Marie Curie Research Fellow at the Natural History Museum in London. His main interest is reptiles, particularly snakes, and his current research revolves around phylogenetics and macroevolution. At the moment, Ian is investigating temporal and among-clade trends in diversification namely in morphological traits such as body size and shape.

He completed his Masters degree at Villanova University, working on squamate systematics across Africa, Southeast Asia, Australia and select Pacific islands. Ian completed his PhD and was a postdoctoral researcher at the Australian National University, where he carried out his doctoral research on identifying and modelling macroevolutionary patterns and diversification dynamics of Australian vertebrates.
