I'm a research scientist and professor, my areas of expertise are in evolutionary biology, evolutionary ecology, ecosystem ecology, host-parasite dynamics, coevolution, biological control, molecular systematics, molecular ecology, nematology, microfauna, mesofauna, and meiofauna.
I mostly fix stuff that is factually or grammatically incorrect, but I also have an eye for folks who add irrelevant content in order to highlight themselves or their own perceived contributions to a topic.
