We work on understanding how ecology impacts evolution through deep-time from the origins of animals to the present. The first animal communities are found in the Ediacaran time period, 580 million years ago.  The oldest of these communities consisted of sessile benthic organisms that lived in the deep-sea.  Therefore, to understand how macro-ecology has changed through deep-time, we study a wide range of different benthic communities from the fossil record and in the modern Antarctic and deep-sea. Using statistical and theoretical models we reconstruct how species interacted with each other and their environment and explore how these relationships influence macro-evolutionary patterns over the last 580 million years.

Current research topics include:

• Ecology and evolution of of early animals

• Marine ecology through deep-time

• Antarctic ecology and ecosystem resilience

• The evolution of life in the Universe
