I am currently a research fellow at Ludwig Maximilian University of Munich. I previously conducted postdoctoral work in the USA, Estonia and Poland, and graduate studies in the UK.
Evolutionary biology and paleontology are the central themes to many of my research interests. I see particular value in the study of large scale evolutionary patterns and processes, using both living and fossil taxa, in order to tease out generalities relevant across the Tree of Life. My specific research interests include: macroevolution - phylogenetic comparative methods - living and fossil fishes - macroecology - morphometrics - multivariate methods - evolutionary biology - phenotypic evolution - diversification - molecular clocks - land plant evolution - moth evolution R packages and other software used include: ape - phytools - RRPP - OUwie - geomorph - rfishbase - geiger - mvSLOUCH (package contributor) BAMMtools - paleotree - MonoPhy - ggplot2 - coda - surface - mvMORPH tpsDig - tpsRW - tpsUtil - TNT - BAMM - BayesTraits - HPC cluster use |
