Paul was born and raised in southeastern Massachusetts, just outside of Boston. He got his undergraduate and master's degrees in Biology and Marine Biology, respectively, at the University of Massachusetts Dartmouth and a PhD in Ecology and Evolution at Stony Brook University. After a four-year post-doc in the Department of Fisheries and Wildlife at Michigan State University, he began teaching at Humboldt in 2014.
