My research interests encompass the cellular and molecular events that are involved in maintaining articular cartilage tissue homeostasis, and the mechanism/s that propagate degeneration of the tissue as observed in the pathology of osteoarthritis. Osteoarthritis is a multi-factorial disease and one of the major risk factors is excessive mechanical load i.e. through sports injury, obesity. As an Academic Fellow within the Arthritis Research UK Biomechanics and Bioengineering Centre, and based in the School of Biosciences I manage the mechanical loading laboratory, where my research area is the identification of signalling pathways that mediate either anabolic or catabolic responses in connective tissues, in particular articular cartilage and intervertebral disc. More specifically, my research interests are:-

  • the role of the chondrocyte cytoskeleton (Figure 1), in particular the vimentin intermediate filaments, in sensing the application of a load on to the articular cartilage surface, and how these intracellular networks transduce these mechanical signals into a biochemical response.

  • Understanding the mechanisms involved in cytoskeletal element dysregulation, as observed in osteoarthritic human cartilage and its relevance to tissue degeneration.
  • Investigating the involvement of the cytoskeletal elements in intervertebral disc cell mechanotransduction.
  • Delineating the role of the β-catenin canonical and non-canonical pathways in transducing mechanical signals in articular cartilage.
  • Investigating why ankle osteoarthritis only develops as a result of previous mechanical trauma.
  • Investigating mechano-regulation of microRNAs in articular cartilage.

Collectively, the aims of my research and the projects that I am involved in are to (1) determine how important the cytoskeletal elements are in transducing mechanical signals that influence cartilage chondrocyte homeostasis and (2) understand the underlying mechanisms of cartilage destruction propagated by abnormal mechanical load.
