Professor Ludwig works on foundational issues in the philosophy of language (esp. logical form and semantics), the philosophy of mind and action, epistemology, and metaphysics, though his interests extend to every area of philosophical inquiry. He taught at the University of Florida from 1990 to 2010 and was the Colonel Alan R. and Margaret G. Crow CLAS Term Professor from 2008-2010, when he joined the philosophy department at Indiana University, Bloomington.

He is also the author most recently of two books on collective agency: From Individual to Plural Agency: Collective Action 1 (OUP 2016) and From Plural to Institutional Agency: Collective Action 2 (OUP 2017).
