Dr Chapman ran the electron microscopy facility at the Clinical School from June 2001. A tutor in the Discipline of Anatomy and Physiology since 2002, Dr Chapman completed his PhD in 2003 and became a full-time lecturer in the Discipline in 2004 teaching Human Biology, Anatomy and Histology. He is currently the coordinator of histology in Medical Sciences and coordinator of the Bachelor of Medical Research unit CHG113/114 Histology and Cell Biology.
Research Interests
Dr Chapman’s research interests have primarily focused on the cell biology of marsupial reproduction and, in particular, the structure and functions of the egg, its surrounding vestments (perivitelline space, zona pellucida, mucoid coat, shell membrane) and the contribution to these from the upper reproductive tracts. He has especially been interested in the glycoconjugate composition of the zona pellucida during oocyte development and its changes during transit through the oviduct. Recently, Dr Chapman has also been involved in characterising the ultrastructural changes to the brains of rats following injury over several time periods to determine the plasticity of neuronal regeneration.He received an IRGS grant to look at the ability of olfactory ensheathing cells to phagocytose bacteria and thereby prevent infection of the CNS through this route, which involved co-supervision of an Honours student with Associate Professor Inn Chuah.
Teaching
Dr Chapman is unit coordinator for the first year Bachelor of Medical Research core unit CHG113/114 Histology and Cell Biology. This involves teaching the histological basis of cells, tissues, organs and systems, both at the light and electron microscopical levels. As part of this, Dr Chapman has introduced Virtual Microscopy for the first time, that allows students to view histological slides on a computer, from macroscopic to 400x microscopic magnifications, as if using a real microscope. Dr Chapman is also responsible for teaching histology and basic medical science to 1st and 2nd year medical students and has provided a series of lectures on the reproductive systems to Human Biology students.
