I am the co-editor (with Joseph Margolis) of The Quarrel Between Invariance and Flux: A Guide for Philosophers and Other Players (Penn State Press, 2001). My articles have appeared in several journals and anthologies, the former including Ethics and Information Technology, Journal of Human Computer Interaction, and Educational Philosophy and Theory. My current studies are in the philosophical foundations of knowledge organization.
I have taught at Drexel since 1981, and I was the recipient of the Christian R. and Mary F. Lindback Foundation Award for Distinguished Teaching in 1992. Among the courses I currently teach are Aesthetics, Epistemology, and the Seminar in Rationalism and Empiricism. I maintain an extensive multi-media web site for the exclusive use of my students, www.catudal.org. From 1991 to 2001, I also taught courses in aesthetics and the philosophy of music at the Curtis Institute of Music.
I served as the Philosophy Program’s first Director, from 1987 to 1991, and again from 1993 to 1997, and 2007 to 2010. I served briefly as Department Head (2003), before being appointed Vice Provost for Academic Affairs (2003-2005). Prior to serving as Vice Provost, I served as an executive officer of Drexel’s Faculty Senate (2000-2002). For my “consistent and outstanding service to Drexel University,” I was presented with the Provost’s Award in June 2005.
