Research interests:

Applied immunology, medical microbiology, microbial pathogenesis

Current research:

Dr McConnell is a Senior Research Fellow in the Department of Microbiology and Immunology. Current research in her group, as part of a wider Ag Research MBIE funded project (with Aladin Bekhit Food Science and Alan Carne Biochemistry), is primarily centered on the immunomodulatory effects of sheep milk in comparison with cow and goat milk, along with the microbiological status of the sheep milk.  The sheep industry is a relatively young industry in New Zealand and the milk is predominantly used for cheese making in addition to some baby formula for the Chinese market. As part of the project she is co-supervising a PhD student Keegan Burrow from the Food Science Department who is investigating the bioavailability of minerals in sheep milk.

As well, Dr McConnell has an interest in the normal microflora of the gastrointestinal tract and is continuing some collaborative work with Dr Heather Brooks in the Department of Microbiology and Immunology on necrotizing enterocolitis (NEC). NEC is an acquired intestinal disease primarily found in premature neonates and which has a high mortality rate. At present, it is a disease of unknown origin, although many factors including microbes, an immature intestinal epithelial barrier and an immature host defense system have been implicated. Current research is centred around the use of probiotic strains of bacteria and how they may prevent disease.

Newer research in the laboratory is centered around collaborations with the Departments of Pharmacy (Dr Greg Walker)and Chemistry (Dr Jaydee Cabral).  We have a fourth year student (Sasheen Dowlath) who is investigating the antimicrobial effects of nanofibres made with a variety of different polymers with the ultimate aim of using any with antimicrobial properties as coatings for medical devices.

Jodie Fleming is in thesis only year of her Masters degree and is investigating the effects of commensal and pathogenic bacteria on wound healing using a thermal wound in 3D human skin equivalents.

We are also hoping to use this model, in association with Jaydee Cabral, to investigate some novel delivery systems to deliver vascular endothelial growth factor to increase the rate of healing.

 Sonya Mros is the senior research technician and lab manager for the group and assists the students with their projects and learning new techniques as well as taking the lead role in externally funded projects
