Research interests (Description)
I am an evolutionary paleobiologist documenting and interpreting the relative contributions of abiotic (e.g., climate) and biotic factors (e.g., parasitism) in driving large-scale ecological and evolutionary patterns in the history of life.
Current research focuses on macroecology, biotic interactions, and biomineralization. For example: How does body size distribution and growth respond to climate warming and related environmental stressors? How does parasitism relate to host biodiversity and disease? How does seawater chemistry affect biomineralization of aquatic ectotherms?
For this purpose, I strive to work across disciplines and find means to test hypotheses with different lines of evidence, ranging from evolutionary ecology, over quantitative and molecular (paleo)biology, to developmental paleobiology, (paleo)parasitology and earth sciences.
I also work in other research areas, principally biogeography, biostatistics and geometric morphometrics, environmental analysis, experimental taphonomy and phylogenetic analysis. I remain active and maintain interest in methods (sample preparation and quantitative analyses) used in all these fields. I would therefore be happy to advise students in these and other areas.
Latest student research includes: diversity and body size dynamics of marine invertebrates, Holocene trends in parasite-host prevalence captured in coprolites and skeletal pathologies, 3D-reconstruction and morphometry as well as experimental taphonomy of invertebrates and vertebrates.

abstract = {Evolutionary transitions of organisms between environments have long fascinated biologists, but attention has been focused almost exclusively on free-living organisms and challenges to achieve such transitions. This bias requires addressing because parasites are a major component of biodiversity. We address this imbalance by focusing on transitions of parasitic animals between marine and freshwater environments. We highlight parasite traits and processes that may influence transition likelihood (e.g., transmission mode, life cycle, host use), and consider mechanisms and directions of transitions. Evidence for transitions in deep time and at present are described, and transitions in our changing world are considered.

Evolutionary transitions of organisms between environments have long fascinated biologists, but attention has been focused almost exclusively on free-living organisms and challenges to achieve such transitions. This bias requires addressing because parasites are a major component of biodiversity. We address this imbalance by focusing on transitions of parasitic animals between marine and freshwater environments. We highlight parasite traits and processes that may influence transition likelihood (e.g., transmission mode, life cycle, host use), and consider mechanisms and directions of transitions. Evidence for transitions in deep time and at present are described, and transitions in our changing world are considered. We propose that environmental transitions may be facilitated for endoparasites because hosts reduce exposure to physiologically challenging environments and argue that adoption of an endoparasitic lifestyle entails an equivalent transitioning process as organisms switch from living in one environment (e.g., freshwater, seawater, or air) to living symbiotically within hosts. Environmental transitions of parasites have repeatedly resulted in novel forms and diversification, contributing to the tree of life. Recognizing the potential processes underlying present-day and future environmental transitions is crucial in view of our changing world and the current biodiversity crisis.
