For almost 20 years, beginning in December 1996, I worked in the Theory of Condensed Matter (TCM) Group at the Cavendish Laboratory -- the physics department of the University of Cambridge. Beginning in 2010 I also worked partly at University College, London for a few years. From 2002 until 2010 I was a Royal Society Research Fellow and for ten years also a College Lecturer at Emmanuel College, Cambridge. Since October 2015 I am what you might call unemployed, though this is at least partly by choice -- let's call it a year's sabbatical for the moment -- and I continue in my role as director of the Apuan Alps Centre for Physics, an independent theoretical physics research centre and events venue in the mountain village of Vallico Sotto, Tuscany, Italy founded in 2004. I also manage the Keil Art Bronze gallery in Via dei Fossi, Florence (opening Christmas 2015) where I am often to be found sneakily doing physics calculations whilst pretending to be a shopkeeper. In 2016 it is intended that the gallery will also host weekly evening physics and art lectures.
My research is principally concerned with the development of highly accurate quantum-mechanical methods useful in understanding and predicting the properties of matter, though I also have a long-standing interest in the foundations of quantum physics. I am also a specialist in massively parallel computing, and routinely develop and run calculations on some of the largest machines in the world. I am an author of over sixty scientific articles and book chapters, and have written a number of widely used international-class software programs, including probably the best quantum Monte Carlo code in the world 'CASINO' (which I continue to develop in collaboration with my colleagues Neil Drummond and Pablo López Ríos). An experienced public speaker and educator, I have given numerous invited talks all over the world along with various lecture courses and thousands of small-group supervisions over many years in Cambridge.
What I do with my time
I do research in quantum physics from my bases in Florence and Vallico Sotto in Italy (having a somewhat 21st-century attitude to physical location, I might actually be found at either of these places at any given time with your best bet being the Keil Art Bronze gallery in Florence). I collaborate in particular with the groups of Richard Needs at Cambridge, Dario Alfè at UCL, and Matthew Foulkes at Imperial College. From Jan 2016 I have 'Visitor' status in the Cambridge TCM Group and indeed intend to actually visit occasionally.
One of my main research interests is the super-accurate quantum Monte Carlo method widely used in computational electronic structure theory; I am the principal author of the CASINO quantum Monte Carlo software, written over many years with my colleagues Neil Drummond and Pablo López Ríos and many other postdocs and students. I also have a long-standing interest in the unorthodox but highly interesting de Broglie Bohm ('pilot-wave') theory of quantum physics.
I own a 15th century monastery in Tuscany that I run as a science institute ("The Apuan Alps Centre for Physics") and events venue, and my wife Sam Keil uses as her Italian art and sculpture studio. Every year I organize workshops and summer schools on various topics at this venue - see the web page for more details.
Off and on since 2001 I have organized the Electronic Structure Discussion Group, a weekly discussion forum where researchers and students in the TCM Group (and interested colleagues in other departments) get together to present and chat about their work.
Should I ever have any free time I'm interested, in no particular order, in antique books, Etruscan archaeology, caving, climbing, and mountaineering, the Victorian explorer Richard F. Burton, old sailing ships, taxidermy, Victorian science (especially the dangerous stuff), Italian poetry, mathematical recreation, and astronomy.Finally, just for fun, I'm working on being a Jerry Lee Lewis impersonator.

The Apuan Alps Centre for Physics
I am the owner of the Towler Institute, a large 16th century former monastery situated on the outskirts of a mediaeval village in the Apuan Alps national park in Northern Tuscany. It hosts my science institute (the "Apuan Alps Centre for Physics") alongside an arts centre (associated with my wife Sam Keil). It is also used as a general events venue. The monastery's chapel hosts scientific summer schools and workshops, plus occasional art events, and it is the ideal summer getaway for people seeking peace and inspiration for work.
