Simon Mills gained his PhD from Queen Mary, University of London in 2009. His thesis, 'Joseph Priestley and the Intellectual Culture of Rational Dissent, 1752-1796', is study of Priestley’s and his circle’s contribution to philosophical and theological debate in the second half of the eighteenth century.
He now works on early modern religious and intellectual history, with a particular focus on religious dissent, correspondence networks, biblical criticism, and the history of philosophy. He has edited a selection of Priestley’s letters to the Unitarian minister Theophilus Lindsey for the website of the Dr Williams's Centre for Dissenting Studies. His other publications include: 'Aspects of a Polymath: Unveiling J. T. Rutt’s Edition of Joseph Priestley’s Letters to Theophilus Lindsey', Enlightenment and Dissent, 24 (2008), 24-53, and 'Joseph Priestley’s connections with Catholics and Jews', Transactions of the Unitarian Historical Society, 24.3 (2009), 176-191. He is a contributor to the forthcoming History of the Dissenting Academies in the British Isles, 1660-1860.
