I am a Senior Lecturer (equivalent to an associate professor) in the Theoretical Physics group, a member of the cross-disciplinary Centre for Complexity Science, and part of the Social and Cultural Analytics Lab in the Data Science Institute here at Imperial. I did my first degree in Natural Sciences (Physics) at Cambridge followed by a PhD here at Imperial, supervised by Ray Rivers. I then spent time as a researcher at the University of Alberta in Edmonton Canada, followed by research positions back here at Imperial, in part as a Royal Society University Research Fellow.
My main interest is in the behaviour of many body systems both in and out of equilibrium. I act as the Imperial node of the EPSRC NetworkPlus collaboration on Emergence and Non-Equilibrium Physics whose title is a pretty good summary of my interests. Currently I am interested in ideas falling under the broad area of complex systems. In particular the properties of Complex Networks, such as the "six degrees of separation", intrigue me. This led me to organise the thirteenth Mathematics of Networks meeting held here at Imperial in September 2014. From a theoretical perspective, I am interested in community detection in networks, networks constrained by time and networks constrained by space. In terms of applications to practical problems I look at many different areas but I am particularly interested in social systems such as bibliometrics (citation patterns and related problems), cultural transmission and archaeology. For instance I have an ongoing archaeology project which emerged out of meeting in Venice in November 2002 of an intriguing EU funded network, ISCOM, involving economists, geographers, physicists and mathematicians. I am part of the Connected Past team organsing events to develop the use of ideas from complexity and networks in the context of archaeological and historical problems. I organised The Connected Past London 2014 here at Imperial in September 2014.
A slightly unusual direction has been my work to develop new visualisations of complex systems using 3D printing. This led to my recent paper Scuplexity: Sculptures of Complexity using 3D printing, see my blog entry about 3D printing and Complexity for more information and links about this work.
I'm have also worked on Quantum Field Theory. My main focus was on many-body problems, a topic known as Thermal Field Theory or Finite Temperature Field Theory. I also studied generic features of QFT such as the nature of multiplicative anomalies and their implications for zeta-function renormalisation.

Kim Christensen and gave a new level 3 physics course (typically taken in the 3rd year) on Complexity and Networks in the Spring of 2014. This is an unusual (for the Physics department) mixture of theoretical lectures and practical computational labs and projects.
I run a number of BSc and MSci undergraduate projects. All my projects are done in pairs and are theoretically or numerically inclined. The Physics MSc project are based on similar topics to the undergraduate ones while the QFFF MSc projects are completely different. See the relevant web pages for lists of projects. Through a combination of hard work and simple luck, the work on some of these projects has been turned into research papers. For a list of papers I have coauthored with undergraduates see the list maintained on the undergraduate student physics pages or look at my own page listing publications with undergraduates.
I am also a personal tutor, looking after the general academic and general welfare of around sixteen Undergraduates and several MSc students from the Quantum Fields and Fundamental Forces MSc.
