Maria obtained a BSc in human nutrition at Trinity College Dublin and a diploma in dietetics at Dublin Institute of Technology. She then undertook a PhD and post-doc position in Dermot Kelleher's lab at Trinity College investigating mechanisms of action of tumour necrosis factor alpha. She then moved to The Scripps Research Institute in California as an American Heart Association research fellow in Nigel Mackman's lab, studying gene regulation in inflammation.
From 1999-2006, Maria was a senior research scientist and deputy head of the Micronutrient Research Section at the Medical Research Council’s Human Nutrition Research Centre in Cambridge, working on the regulation of gene expression in inflammation and vascular disease and the role of cellular and dietary antioxidants in disease.
Current research interests are focused on the following areas:
- Age-related disease and cellular antioxidants
- Resolution of Inflammation – new targets and mechanisms of action
- Dietary, plant and marine bioactives – mechanisms of action in inflammation and chronic disease
- Novel therapeutics for cancer

Nrf2 in disease prevention and therapy
Role in inflammation
During inflammation, intracellular signalling pathways are activated to protect immune cells. The antioxidant response element (ARE) is present in the regulatory regions of several classes of antioxidant, detoxification and cytoprotective genes. The NF-E2 family of transcription factors bind to the ARE and mediate gene transcription. We are investigating the role of members of the NFE2 family, including Nrf2 and Bach1, in activation of the ARE signalling pathway in response to pro-inflammatory stimuli and examining crosstalk with other signalling pathways.
Over the past few years, we have identified several natural products that activate the Nrf2-anti-oxidant response pathway and have been studying their mechanisms of action and potential as future pharmaceuticals or nutraceuticals, including various flavonoids, alpha lipoic acid and novel chalcones and triterpenoids.
In addition, in collaboration with Mark Searcey (UEA), we are designing new molecules that directly interact with Nrf2 to activate this important pathway.
TREM-2 in inflammation
TREM-2 is a receptor on myeloid cells. Unlike other members of the TREM family, TREM-2 appears to exert anti-inflammatory effects in these cells. We are studying the regulation of TREM-2 in these cells and its expression and role in various cell types.
Natural products and analogues as anti-inflammatory and anti-proliferative agents
Immunomodulatory effects of vitamin D
The role of vitamin D in calcium homeostasis is well established. However, 1,25-OHD also exhibits potent antiproliferative and differentiative effects and exerts immunomodulatory effects in innate and adaptive immunity. In collaboration with David Hughes, Andrew Wilson, Darren Sexton and Ian Clark (UEA), we have been investigating the molecular mechanisms by which the active form of vitamin D modulate inflammatory mediators in human airway epithelial cells.
Cardiovascular and anti-inflammatory benefits of flavonoids and their metabolites
In collaboration with Colin Kay (UEA), we are investigating the collective beneficial activities of a series of flavonoids and their metabolites in monocytes, endothelial and smooth muscle cells and investigating their intracellular mechanisms of action.
Novel leads from natural product-based libraries
Natural products serve as a basis for developing novel therapeutic compounds. In a series of collaborations, we are identifying anti-inflammatory and anti-proliferative mechanisms of action of specific natural products and their analogues. We are studying the selective mechanisms of action of compounds from natural product-based libraries, with Mark Searcey’s group (UEA). In collaboration with Rob Stockman (Nottingham) and Sue Matthews (UEA), we are studying analogues of marine and plant natural products and their effects on pro-inflammatory signalling pathways. With Anne Osbourn (John Innes Centre), we are studying biological effects of triterpenoids in animal cells.
