I didn't see any indication of this being the case for Dr. May, but people are often confused about this when non-professors teach college/university-level courses. In this case they typically have another title such as "lecturer", "instructor", or "fellow". This became a minor issue during the 2008 Presidential campaign with Obama's claim of being a "Constitutional law professor"; he did not hold a professorship and his formal title was "senior lecturer".
