I am responsible for two MSc advanced courses and two MSc research modules:

  • Biocomputing 1: Python for beginners.
  • Biocomputing 2: Python for advanced students.
  • Evolutionary Genomics
  • Biological Data Analysis

I also regularly teach in the following modules:

  • Molecular Phylogenetics (MSc advanced module) - I teach a practical on "Molecular evolution and selection"
  • Computational analysis of transcriptomes and proteomes (MSc advanced module) - I teach a practical on "Intro to Genomics and Transcriptomics"
  • Animal Evolutionary Ecology (BSc module) - I give a lecture on "Ageing in animals - evolutionary and ecological considerations" and supervise student projects.
