Daniel Lawson, Bristol.

This is the homepage of Daniel Lawson, Research Associate in the Department of Mathematics at the University of Bristol. My research is highly interdisciplinary. Using methods from statistics, modelling, game theory, dynamical systems, data mining and statistical physics I've worked on genetics, evolution, historical dynamics and energy markets. For a (non-technical) description of this work see the research, page, with the papers referenced over in publications.

Some details of my teaching are available, as is further information about me, and my contact details. You can look me up on Google Scholar.

My current application area is genetics, with a serious amount of work devoted to ChromoPainter/FineSTRUCTURE, for which we've produced a usable, flexible and powerful set of tools. I'm currently working on statistical and data-mining techniques to scale this analysis up to "all the genomes of all people", an ambitious goal that requires some new statistical and data mining methodology.

A second, long-term (in progress for several years) development is the maturing of work with Neeraj Oak on modelling the collapse of historical states. It turns out that a simple dynamic game-theory model for the internal politics of a state can robustly lead to periodic collapse events that occur when states appear at their most powerful and stable. This has interesting (and of course speculative) implications for modern states.
