I am a geologist, a paleontologist, and a network scientist. My research interests are centered around understanding how major geological events, long-term ecological changes, and historical contingencies have shaped the evolutionary history of the Metazoa. To address specific questions on the biosedimentary record, I use a cross-disciplinary approach that combines paleobiological and geological data, with modern spatial statistical and network science tools. I am currently a postdoctoral fellow at the Integrated Science Lab (IceLab), a hub dedicated to cross-disciplinary research located at Umeå University in northern Sweden. IceLab research covers a wide range of scientific questions on the fossil record, social networks, phytoplankton, DNA folding, microbial economics, invasive species, and antibiotic resistance.

Preprint: Low-Latitude Origins of the Four Phanerozoic Evolutionary Faunas. Using a multilayer network representation of the fossil record, we demonstrate that Phanerozoic oceans sequentially harbored four evolutionary faunas. This work resolves the conflict between two central hypotheses in macroevolution: The Three Great Evolutionary Faunas and the Mesozoic Marine Revolution.
