PUBLICATIONS

Publications are organized alphabetically within each year. I have published over 110 papers, so you if you're looking for a particular reference it will help if you search by year, collaborating author or topic. PDFs of three popular reviews (diseases of lobsters - Shields et al. 2006, diseases of blue crabs - Shields & Overstreet 2007, and parasites and diseases of brachyuran crabs - Shields et al. 2015) are available below.
