My PhD investigated the immunomodulatory properties of an organic extract of Manuka honey in vitro. This predominately involved working with the human cell lines including; HaCaT keratinocytes, HUVEC endothelial cells, THP-1 macrophages and a co-culture angiogenesis model; looking at both immunomodulation and molecular regulation of anti and pro-inflammatory markers.  Since completion I have continued to research the effect of natural products in particular plant derived terpenoids and flavonoids which have shown to possess important activity through the transcription factor PPAR gamma. Currently I am investigating the potential these compounds possess in regulating angiogenesis; in particular anti-angiogenic activity and how hypoxic conditions may be a contributing factor. This work has the potential to lead to alternative therapies for a huge range of diseases.
