Steven McMullen is an Assistant Professor of Economics at Hope College. He specializes in education policy, and the role of ethics and theology in economics. He is currently working on a book about animal ethics. Most of his writing is available at http://stevenmcmullen.wordpress.com.
While the scientific and policy issues raised in the encyclical will get the most press attention, Francis is primarily doing theology. He emphasizes repeatedly that non-human creatures are not here only to serve us.
