Dr Robert Graham BSc (Hons), PhD

Senior Lecturer in Entomology

Teaching Duties

  • MSc Entomology
  • MSc Integrated Pest and Disease Management
  • MSc Conservation & Forest Protection 
  • MSc Ecological Applications

Research Interests

My research interests include invertebrate pathology and host-microbe evolution; particularly in understanding how microorganisms regulate and manipulate host species to maintain stability and sustainability within ecosystems; to understand the role that disease and endosymbionts play in driving host populations dynamics, and how we may utilise this knowledge to develop successful integrated pest management strategies for globally-important crop pests.
