Research interests

Inhibition of disease-associated protein aggregations
In particular, I am interested in identifying how and which post-translational modifications (PTMs) can lead to protein conformational change as evidenced by protein aggregation and identifying potential inhibitors (particularly plant-derived anti-oxidants) of this often disease-associated phenomenon. To enable this, a number of model systems to allow measurement of aggregation have been developed and in the long term, the efficacy of combining identified inhibitory species in an appropriate drug delivery format will be studied.

The phenomenon of redox switching by plant-derived anti-oxidants
One observation which has arisen from these studies has been the phenomenon of redox switching of anti-oxidants i.e. instead of expected beneficial effects, the anti-oxidant becomes harmful acting as a pro-oxidant. This switching phenomenon has been observed elsewhere and may be why the use of anti-oxidants has not translated well from promising in vitro results to in vivo clinical trials. Switching is affected by threshold values for concentration, metal ions, and pH. Comprehensive knowledge of the redox switch points for many anti-oxidants is currently unknown but may have significance for therapeutic and health strategies e.g with regard to anti-oxidant routes within cellular compartments.

Areas of research supervision

  • Deimination of prion protein
  • Anti-microbial action of green teas
  • Anti-microbial action of essential oils
  • Inhibition of lysozyme aggregation by punicagalin
  • Identification and comparison of bacterial species found on fomites and in animal specimens.
