From 1997 onwards, he has been closely associated with the Theory of Condensed Matter group (TCM) of Cambridge University's Cavendish Laboratory.
[1] In October 2010, Towler became a postdoctoral research associate at the Department of Earth Sciences, University College, London,[1] although he retained a desk in TCM until 2015.
[1] Towler developed the Cavendish Laboratory's de Broglie–Bohm simulation software LOUIS[4] and is one of the principal authors of the Cambridge quantum Monte Carlo code CASINO.
[5] Earlier, Towler had maintained a resources page for the electronic structure program for the CRYSTAL software package.
[1] In 2010, together with Antony Valentini, he organized a conference on the de Broglie-Bohm theory the Apuan Alps Centre for Physics in late August 2010, hosted at the Towler Institute and attended by many leading physicists.
