Research interests:

Infectious diseases, antimicrobial resistance, host-pathogen interaction, microbial pathogens, nanomedicines

Current research:

Our research is focused on recalcitrant ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) pathogens; especially hard-to-treat clinical isolates involved in multidrug resistance, biofilm infections and persistence. We are especially interested in bacteria that have been categorized as "critical" priority pathogens by the World Health Organization. This includes multidrug resistant organisms that cause severe and often deadly infections and therefore pose an enormous threat in hospitals.

To address this issue, our research focuses on fighting infectious diseases and tackling antimicrobial resistance using innovative and interdisciplinary approaches. 

Our lab seeks to  1) understand how microbes cause disease, 2) fight antimicrobial resistance with novel nanomedicines, and 3) develop new antimicrobial strategies.

Postgraduate opportunities: 

Interested candidates with a BSc(Hons) or MSc degree are highly encouraged to apply if their research interest and experience matches any of the following themes: Microbiology, Immunology, Biochemistry, Genetics, or Bioinformatics. 

All candidates must be eligible for admission to the University of Otago and apply for a MSc or PhD scholarship (https://www.otago.ac.nz/graduate-research/scholarships/index.html). The scholarship is available to both domestic and international students. International students should have a look at the International Office (https://www.otago.ac.nz/international/index.html) for entry requirements and contact the lab beforehand.

If you are interested in joining our lab, please send a cover letter including current research interests, a CV including all published work, a summary of previous research (if applicable), full academic transcripts, and contact information for two-three references.
