Professor Tim Coulson

Research Interests

My group and I research how demographic rates vary across genotypes, phenotypes and environments. We identify the ecological, evolutionary and conservation consequences of this variation. We use a mix of field observations, laboratory experiments, statistical analysis of data and the construction and analysis of mathematical models. 

Research focuses on mammals, birds and invertebrates. If you are interested in working in the group please get in contact describing:

  • the questions you plan to address
  • the study system you plan to use and
  • the funding bodies most likely to support your proposed work
