My research focusses on the impacts of stochastic environmental variability on population processes affecting ecological and evolutionary dynamics.

I combine analytical, simulation and statistical modelling approaches to investigate how different forms of environmental variation (spatial and/or temporal) drive changes in population size and behavioural decisions. Where possible, I also try to link these approaches to data from natural populations.

Areas of Expertise

  • Complex dynamics
  • environmental stochasticity
  • species–environment interactions
  • dispersal
  • species–species interactions.
  • coloured stochastic processes
  • synchrony
  • spatio-temporal dynamics
  • data analysis
  • quantitative approaches
  • Saltmarsh

Teaching

  • BIO109 Core Skills for Biological Sciences

    This module is divided into three sections, scientific writing, data analysis and chemistry, which will equip students with the core skills needed throughout their degree program. The content of the module includes understanding the different types of data that can be measured and collected, the tools to formally present and analyse data and data analyses, and practical applications of spreadsheet software. There is a 'hands on' focus on dealing with data and developing basic mathematical and statistical analytical skills. Furthermore this module introduces first year undergraduates to the key skill of scientific writing, developing their ability to locate, understand, evaluate and communicate scientific information. Basic chemistry will be covered as a foundation to its importance to biological processes.

  • BIO347 Tropical Ecology and Conservation - Borneo Field Trip

    Borneo is a hot spot for biodiversity both in regards to terrestrial and marine ecosystems. This module is a residential field course which will explore ecological and conservation principles in tropical rainforests and marine ecosystems.

  • BIOM25B Science Skills and Research Methods

    This intensive lecture and practical based module covers science skills for students wishing to pursue postgraduate studies, including MSc, MRes, MPhil and PhD degrees. It will teach students how to make good use of library and internet resources (including Web of Science, Voyager and Blackboard), to design and analyse their experiments, and to make presentations of their data during conferences and symposia. It will provide PG students in the Department of Biosciences (and other Departments in the College of Science) with the research and analytical skills necessary to carry out their research projects. It will teach them how to formulate and test scientific hypotheses, and how to generate and analyse scientific results using a variety of research methods. Lecture topics include Reporting and Presentation skills, Numerical skills, Philosophy and Methodology of Science, and Biostatistics. The lectures are taught during the first part of the Semester. The module is examined through a combination of CA (50%) and Examination in the form of a MCQ test (50%). Basic reading: Whitlock, M. and Schluter, D.
