Summary

 

Summary

Note there is more than one Tim Evans at Imperial College (the other is a medic).

My ORCID identifier is http://orcid.org/0000-0003-3501-6486.

There is more information and my blog on netplexity.org. 

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. This is a Tag cloud based on the abstracts of my work since 2004.

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.  From a theoretical perspective, I am interested in how we need to change the way we look at networks when there are strong constraints. These could be internal constraints creating groups in networks, the problem of community detection in networks, or it could be the behaviour of networks constrained by time and networks constrained by space. 

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.  


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.  

More Information: More Information about my work can be found under the research links from this page, on my pages at netplexity.org, on the Tim Evans figshare archives.  The Tim Evans Google Scholar page has a complete list of my work and there are many other links found on my Tim Evans Publications and Social Networks page.

Teaching


Kim Christensen and I started 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. The course was highlighted as a good example by the external examiners in the summer of 2016.

I have also started teaching the first half of the third year Statistical Mechanics course (level 3 physics) since Autumn 2019.  This focusses on models of Percolation. 

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 projects 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 several students.
