I taught critical thinking, moral, and political philosophy at Marygrove College in Detroit, Michigan until the College closed its undergraduate programs in Fall of 2017. I am now a free agent. I got my Ph.D. in philosophy from Wayne State University (also in Detroit) in 2003. I did my dissertation on human rights there. I work on questions of normativity in argumentation, the historical relationship between philosophical thinking about argument and about moral judgment, and on the ontology of argument. Recently I’ve begun research for a project on the pragmatics of multi-modal arguments. I was a Visiting Research Fellow with CRRAR at the University of Windsor from 2009-2013. I am also a member of AILACT. My blog RAIL is devoted to scholarly issues around reasoning, argumentation, informal logic and critical thinking. I have pages at LinkedIn, and Academia.edu as well. All opinions on this blog and the rest are my own.
