About

I lead the Deep-time Ecology Group and am an associate director of the Leverhulme Centre for Life in the Universe. I am also a fellow of Newnham College.

My research investigates the role of ecological processes on evolution through deep-time, from the first animal communities of the Ediacaran, to the present.

The first animal communities are found in the Ediacaran time period, 580 million years ago, which consisted of sessile benthic organisms that lived in the deep-sea.  Therefore, to understand the drivers of early animal evolution, I study a wide range of different benthic communities from the fossil record and in modern systems such as tropical coral reefs and Antarctic communities.  To collect fossil data in the field, I use novel field-based laser-scanning techniques to digitally capture entire rock surfaces.  My work on modern systems uses data collected using scuba diving and AOV and ROVs to create 3D digital models.  

My work is inherently interdisciplinary, utilising techniques from across evolutionary biology, mathematics and palaeontology to revolutionise our understanding of these early animals and modern benthic communities.  I reconstruct how species interact with each other and their environment, and what the driving factors behind these interactions are.  These results then feed into theoretical models to explore how these relationships influence macro-evolutionary patterns over the last 580 million years.
