Robert Smith? (firstname.lastname@example.org) is a professor of biomathematics at the University of Ottawa. He once combined his day job with pop culture and in doing so accidentally invented the academic sub-discipline of mathematical modelling of zombies. He uses mathematical models to predict the spread of diseases, from HIV to malaria to Ebola. He's also the foremost authority on the spread of Bieber Fever, but let's not worry about that one. He has eleven books on academia and/or pop culture to his name, most recently Mathematical Modelling of Zombies and The Doctors Are In: The Essential and Unofficial Guide to TV's Greatest Time Lord.
