Professor in theoretical marine ecology at AQUA, DTU. Deputy chair in the Centre for Ocean Life.

My mission is to simulate global ecosystems for understanding the past and present, and to inform policy and management about our future

I combine theoretical physics with ecology to make quantitative predictions of ecosystems' structure and function, from bacteria to whales, and use evolutionary theory to understand the diversity of life history strategies

My aspiration is to inspire and educate the next generation of quantitative Earth System ecologists


August 2022: New introduction to the theory behind size-based fish community models as used in the Mizer R package:

June 2021: Talk given at ASLO 2021 about how to scale from simple "first principles" of chemistry, diffusion physics, and geometry to the entire global unicellular plankton ecosystem. Includes discussions on biodiversity at different scales, metabolic modelling of a cell, and emergent temperature scaling. See also the online simulator

August 2019: Finally out on Princeton University Press: "Fish Ecology, Evolution, and Exploitation".  Three introductory videos here:,, and

I am currently involved in the courses:

Research Interests

I want to understand how life in the ocean is organised, why marine organisms look and act the way they do, and how marine ecosystems react to perturbations like  fishing, species removals/invasions or climate change. More specifically I work on:

Previously I have worked with sand ripples under surface waves and barchan dunes in deserts.

Student projects:

I have a number of possible  student projects available for students related to the impact of fishing and climate change on marine and fresh water ecosystems. The projects ranges from applied projects on specific ecosystems to abstract theoretical topics. Send me an email if you are interested in learning more.
