In addition to his research papers, Ronan's popular account of the quest to discover and classify all the finite building blocks for symmetry (the finite simple groups) was published in 2006. In 2008 it formed the basis for a series of BBC radio broadcasts. In his research work he is an expert on the theory of buildings, with a standard text on the subject, now being reissued in paperback. Apart from his professional work, he has acted in many operas at the Lyric Opera of Chicago, danced in the Nutcracker, and maintains a blog on opera, ballet and theatre reviews.
