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 how macro-ecology has changed through deep-time, I study a wide range of different benthic communities from the fossil record and in the modern Antarctic and deep-sea.  To collect fossil data in the field, I use novel field-based laser-scanning techniques from aerospace to digitally capture entire rock surfaces.  My work on modern systems uses data collected using AOV and ROVs to create 3D digital models.  Through the application of statistical and mathematical ecology to the fossil 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.
