Joost Raeymaekers

After a PhD in Biology at the University of Leuven in Belgium, and amazing years as a postdoc at McGill University in Canada, the University of Basel in Switzerland, and NTNU in Trondheim, I finally discovered Nord University, where I joined the Faculty of Biosciences and Aquaculture.

My main research areas include population genetics and evolutionary ecology. I am particularly interested in local adaptation, ecological speciation, adaptive radiation, host-parasite interactions and eco-evolutionary dynamics.

At Nord University, I am teaching Genomics & Bioinformatics (BI229F), Biological Data Analysis (BI224F, BI300F, BIO9000) and Population Genomics (BIO9001).
