It is with great sadness that we all mourn the unexpected loss of Professor Mike Bull; a close and long time collaborator of the LEGS lab and supervisor to some of the current students. Mike’s long and extremely successful research career advanced our understanding of evolutionary ecology, reptile conservation and host parasite relationships; as documented in the nearly three hundred peer-reviewed journal articles he authored. He is remembered by his numerous collaborators and students for not only his analytical and insightful thinking, but also for his kindness, eternal good mood and questionable humour.
