      Teaching

      The courses I have been teaching most recently are:
       

      Physics 3A03: Introduction to General Relativity

       
      This is an introductory course on Einstein's theory of General Relativity, aimed at upper-year physics undergraduates.


      Graduate Courses in High Energy Particle Physics

       
      I teach a variety of graduate courses, aimed at students in high energy particle physics. Among the courses recently given are: Introduction to the Standard Model, and Introduction to Effective Field Theories.

       


      Research Interests

      I am an unabashed high-energy particle theorist whose wild oats were sown working in string theory, but my research interests have since taken a more phenomenological turn. At present my interests lie at the interface between string theory and lower-energy physics, with a particular emphasis on how the discovery of D-branes (and the realization that we may be trapped on one) may have observable consequences in experiments and in cosmology.  I have also been a tourist in some of those fields which are related to my own, and am interested in most of the neat applications of theoretical physics.

      To the extent that there is a theme to my research, it would be the use of effective field theory techniques throughout high-energy physics and other fields. (See here for an Ode to this wonderful tool.) These techniques permit a general understand of the low-energy (or long-wavelength) behaviour of any physical system. They are particularly apt for our present situation in particle physics, where it appears that the energy scale of any unknown physics beyond the Standard Model is high compared to those that are experimentally accessible.

      But part of the beauty of these techniques is that they are also applicable in other areas of physics and so they permit a unified perspective towards theoretical physics as a whole. An important example of this is the application to Goldstone Bosons, which are useful in Condensed-Matter, Nuclear and High-Energy Physics.

       


      Selected Publications

      Here is a selection of recent areas on which I have worked:
       

       BOOKS

      1)     The Standard Model: A Primer, C.P. Burgess and G.D. Moore, Cambridge University Press (2006): This graduate textbook uses the Standard Model of particle physics to introduce the techniques of Quantum Field Theory. The intention is to provide in this way both a practical introduction to calculating in field theory, and an introduction to the phenomenology of the Standard Model.

      A Brief Bio

      I was born in Manitoba and was raised in various places around Western Canada, Ontario and Europe.

      I received my B.Sc. in a co-op programme, with a joint honours in Physics and Applied Math from the University of Waterloo. I did my doctoral work in Theoretical Particle Physics at the University of Texas in Austin under the supervision of Steven Weinberg.

      After doing a postdoctoral stint at the Institute for Advanced Study in Princeton, in 1987 I joined the faculty at McGill University, where I was made James McGill Professor in 2003. I am presently a professor with McMaster University's department of Physics and Astronomy and am an Associate Member at the Perimeter Institute.

      I was a Killam Fellow from 2005 - 2007 and elected a fellow of the Royal Society of Canada in 2008.
