I am interested in a broad range of fundamental and applied questions on the interface between ecology, epidemiology and evolution. I use a combination of mathematical modelling, ecological experiments with model species, and field observations from natural ecosystems, to understand the processes and mechanisms that allow population persistence and species coexistence. I like to base my theoretical research in the context of important applied problems such as food security, biodiversity loss and invasive species. This has led me to work on species as diverse as baculoviruses, honey bees, parasitoid wasps, porpoises, seagrass and triggerfish.

Teaching

  • BIO249 Introduction to field ecology

    This residential field course comprises practical work employing techniques appropriate to sample biodiversity and environmental parameters from a range of terrestrial and freshwater habitats (woodlands, grasslands, freshwater systems). Students will learn techniques for the identification of species, practice recording accurate field notes, and gain experience in the analysis and presentation of ecological data. Furthermore students will be able to recognise different temperate habitats and the indicator species associated with them.

  • BIO252 Ecological Data Analysis

    This module introduces students to the basics of analyzing ecological data, using the R Software Environment for Statistical Computing. The topics covered will be also broad enough to be equally applicable to basic data analysis across biology. Students will receive 7 computer-based workshops/practicals, complemented by 7 lectures before each workshop. Furthermore, a weekly drop-in stats help session will be provided, as well as help through a course Facebook page. The module will cover 5 key themes: 1). Data analysis and statistics, reproducibility and the R Software Environment; 2). Data management; 3). Data visualization; 4). Data analysis - The general linear model; 5). Data analysis - Presentation of results and outline of more advanced methods. The module will be subject to continuous assessment consisting of 6 pieces of computer-based work (70% of final mark), which will require the students to carefully complete all course work assigned on a weekly basis ('independent learning'), in order to be able to complete the assignments. A further 30% of the final mark will consist in a data analysis report, to be completed after the end of the course. Weekly readings and non-assessed computer-based exercises will be assigned, too.

  • BIO334 Advanced Data Analysis

    This module extends core knowledge of statistical computing to cover a range of more specialized topics of particular importance to the analysis of real world biological datasets, such as those collected for final year undergraduate research dissertations. We use the R software environment; building on experience of this gained during the core Second Year module, BIB214 ¿ Ecological Data Analysis. Students will be guided through 5 computer-based workshops / practicals, including brief introductory lectures to each topic. Further help will be provided through a series of drop-in sessions. The workshops, and associated additional guidance, will cover 5 key themes: 1) Linear modelling refresher, 2) Generalised Linear Modelling A - Count data, 3) Generalised Linear Modelling B - Proportion data, 4) Non-parametric analysis, 5) Introduction to grouped data. The module will be subject to continuous assessment, consisting of 4 pieces of computer-based work, throughout the course. In addition, students will complete a coursework assignment after the course, where they will gain additional experience of analysis and interpreting biological data.
