Reviewer
Refereed for several journals since about 2015.
I am prioritising papers of journals associated with scientific societies in my field. I currently decline to referee papers for journals published by certain publishers who charge our university library excessive prices. See a statement by six scientific societies° and a text by Randy LeVeque° for more information on the current state of academic publishing.
