Research interest
My research program combines a fundamental in-vitro research approach, examining the time varying response of the lumbar spine tissues, with in-vivo human research, examining biological responses to cumulative loading exposure from both pain generating and tissue altering/injuring perspectives. Work in my laboratories involves developing approaches to assess workplace cumulative loading exposure and injury in conjunction with in-vitro tissue mechanics studies investigating the injury pathways from repetitive loading. Currently, quantifying the influence of modifiers such as repetition and magnitude of exposure to establish the relationship between cumulative loading and low back pain is a major focus in my research. This knowledge will complement existing epidemiological data, linking cumulative loading and low back pain, for setting exposure limits and helping to prevent low back injuries.
