Introduction
I am a computational palaeobiologist investigating the drivers of biodiversity patterns across a range of temporal and spatial scales. My research primarily focuses on the co-evolution of life and the environment, and evaluating the influence of data incompleteness on our perceptions of the geological past. To do so, I integrate a range of interdisciplinary tools and sources of information, such as ecological niche modelling, Earth system modelling and fossil occurrence data.

Article
Full-text available
Today, warm-water coral reefs are limited to tropical-to-subtropical latitudes. These diverse ecosystems extended further poleward in the geological past, but the mechanisms driving these past distributions remain uncertain. Here, we test the role of climate and palaeogeo- graphy in shaping the distribution of coral reefs over geological timescales...
Article
Full-text available
Paleotemperature proxy records are widely used to reconstruct the global climate throughout the Phanerozoic and to test macroevolutionary hypotheses. However, the spatial distribution of these records varies through time. This is problematic because heat is unevenly distributed across Earth’s surface. Consequently, heterogeneous spatial sampling of...
Article
Full-text available
The latitudinal biodiversity gradient (LBG), in which species richness decreases from tropical to polar regions, is a pervasive pattern of the modern biosphere. Although the distribution of fossil occurrences suggests this pattern has varied through deep time, the recognition of palaeobiogeographic patterns is hampered by geological and anthropogen...
Article
Full-text available
Reef corals are currently undergoing climatically driven poleward range expansions, with some evidence for equatorial range retractions. Predicting their response to future climate scenarios is critical to their conservation, but ecological models are based only on short-term observations. The fossil record provides the only empirical evidence for...
Article
Full-text available
In the lead-up to the Cretaceous/Paleogene mass extinction, dinosaur diversity is argued to have been either in long-term decline, or thriving until their sudden demise. The latest Cretaceous (Campanian–Maastrichtian [83–66 Ma]) of North America provides the best record to address this debate, but even here diversity reconstructions are biased by u...

1. The open-source programming language ‘R’ has become a standard tool in the palaeobiologist’s toolkit. Its popularity within the palaeobiology community continues to grow, with published articles increasingly citing the usage of R and R packages. However, there are currently a lack of agreed standards for data preparation and available frameworks...
Conference Paper
Ecological Niche Models (ENM), the set of different algorithms and workflows designed to obtain hypothetical maps of species, have been broadly used in studies on current biogeography, macroecology and conservation biology. The field experienced hot methodological debates around 10 years ago, when researchers tested the accuracy of the different al...
Poster
Full-text available
This poster summarises our ongoing research on the impact of using different Plate Rotation Models (PRMs, also know as "Global Plate Models" or "Palaeorotation models") in a palaeobiological framework. These models have become widespread in palaeobiology as they provide a reconstruction of a fossil occurrence's geographic coordinates at time of dep...
Poster
Full-text available
Ecological niche modelling is applied broadly in ecology to model a species’ niche and map suitable habitat. The approach links species’ occurrences with environmental predictors to statistically derive response curves. Although commonly applied to study extant taxa, ecological niche modelling is an emerging method in palaeobiology, providing oppor...
Conference Paper
The availability of large-scale occurrence databases has revolutionized palaeobiology, allowing for investigation of diversity and macroecological trends through deep-time. However, the problem of data absence (i.e. does the lack of a fossil occurrence indicate genuine absence or imperfect detection?) has hindered studies, and potentially biased ou...
Conference Paper
Reconstructions of global palaeoclimate are widely used to test evolutionary hypotheses and to act as a baseline against projected global warming, but their accuracy is hampered by uneven spatial sampling. Whilst the palaeontological community has accounted for biases through estimates of sample-standardized diversity, less attention has been given...
Presentation
Modern zooxanthellate coral (Z-coral) biodiversity decreases from tropical to polar regions. This latitudinal biodiversity gradient (LBG) is remarkably pervasive across numerous extant taxonomic groups. However, projected global warming of 2.0–4.8°C will have profound impacts on the distribution of organisms’ abundance, diversity, and habitats, as...
Poster
Conservation biologists use ecological niche models (ENMs) to estimate the impact of climate change on species’ distributions. This approach attempts to establish the fundamental niche of a species. However, most ENMs are calibrated solely on modern occurrences, which are intrinsically biased/incomplete in geographic and environmental space. Such E...

Data from the geological and fossil record is key to understanding Earth's history, whether it be the evolution of the biosphere, atmosphere, hydrosphere, cryosphere, or the lithosphere. However, due to sampling practises and variable preservation potential, data from the geological and fossil record is often incomplete and biased. This project investigates the potential impacts of limited and uneven spatial sampling on our understanding of Earth's history. In particular, this project focuses on reconstructions of biodiversity patterns and palaeoclimate.
Project
The aim of palaeoverse is to bring the palaeobiology community together through various means. The current focus is on generating a community-driven software package of generic functions for the community. The package will provide auxiliary functions to help streamline analyses, and improve code readability and reproducibility.
