Dr. Richard Bradbury
Adjunct Associate Professor
Dr Richard Bradbury is a clinical microbiologist with expertise in diagnostic microbiology and epidemiology. Dr Bradbury developed his expertise in clinical microbiology over seventeen years working as a medical scientist in clinical diagnostic laboratories, including over three years as the team lead of the Parasitic Diseases Reference Laboratory at the Centers for Disease Control and Prevention in the US.
Richard maintains a research program on parasitic diseases, zoonoses and new diagnostics in both the Australian and global health context. He has worked on several continents and presented at numerous national and international conferences, maintaining engagement with academia, industry and the wider community.
Richard has published over 100 peer-reviewed journal articles and 26 invited peer-reviewed book chapters. He has obtained over $1 million dollars in research grant funding from various sources. Richard has supervised four post-doctoral fellows, one PhD student, and several first-class Honours students to completion.
