G'day
I'm Mark Bugden and welcome to my homepage. I am a research scientist currently working at the Max Planck Institute of Animal Behaviour in Konstanz, Germany.
Although I am currently working in Animal Behaviour, my academic background is in theoretical and mathematical physics, which I still work on occasionally. My two main research programs in this area are in string theory and mathematical aspects of general relativity.
Animal Behaviour
My current research involves studying the collective behaviour of animals in the hydrodynamic limit - that is, when there are a large number of individuals.
Such systems behave as though they are a fluid, and can be described using the mathematics of fluid mechanics. The extent to which this is an accurate description is one of my main research interests, and I am studying this topic through the combination of simulations and quantitative analysis of experimental data.
String Theory
My main focus in string theory and M-theory is on studying the properties of dualities.
A little more specifically, the following list provides a subset of the research topics in string theory/M-theory in which I am interested:
String theory/M-theory
- Geometric, topological, and algebraic properties of various T-dualities
- Abelian T-duality
- Non-abelian T-duality
- Poisson-Lie T-duality
- Non-isometric T-duality
- Spherical T-duality
- Generalised Geometry and Exceptional Generalised Geometry
- Double Field Theory and Exceptional Field Theory
- Courant algebroids, Leibniz algebroids, G-algebroids, and L∞ algebroids
- Solution generating techniques in supergravity/string theory
- T-folds, non-commutative, and non-associative string backgrounds

My research in general relativity focusses on black holes in 4 and higher dimensions. I am particularly interested in the properties of light orbiting black holes.
