August 2022: New introduction to the theory behind size-based fish community models as used in the Mizer R package: https://vimeo.com/743363459.

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: https://vimeo.com/360485996, https://vimeo.com/360485974, and https://vimeo.com/360486042.

Teaching

I am currently involved in the courses:

• 25303 Mathematical biology

• 25304 Differential equations in biology

• 25314 Computational Marine Ecological Modelling

• 25803 Ocean Life Meeting Series

Send me a mail if you  are interested in any of these 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:

• Trait-based models of life in the ocean. See http://www.oceanlifecentre.dk

• Size-structured models of marine ecosystems. See the community calculator and the single-species calculator and the plankton simulator.

• Fisheries induced  evolution. See the evolutionary calculator.

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.
