My Work

Research in my group focuses principally on the cellular and molecular biology of innate immune mechanisms in the lung, particularly in cystic fibrosis and alpha-1 antitrypsin deficiency. I have a particular interest in non-coding RNA expression and function and lead a group that are developing inhaled molecular therapies. Another major aspect of my research is the investigation of the molecular mechanisms underlying sex differences in disease in adults and neonates - this work, to date, has concentrated on studying the effects of estrogen and the contribution of X chromosome-encoded genes and microRNAs.

Potential Projects

Potential PhD projects available in my group for which the appropriate expertise, infrastructure and national/international and industrial collaborations exist include, but are not limited to, combinations of the following types of studies:

- Biomarker discovery and identification of altered gene and noncoding RNA expression patterns associated with infection, non-infectious disease, disease severity, prescribed medications etc. [qPCR; TaqMan miRNA assays; miRScript arrays; Open Array, Nanostring or ArrayStar profiling; Next generation sequencing]

- Functional studies of miRNA and lncRNA [in silico bioinformatics analysis, qPCR, western blotting/ELISA, overexpression and knock down studies, luciferase reporter assays, cloning & site-directed mutagenesis, miR-CATCH, in situ hybridisation, immunohistochemistry, chromatin immunoprecipitation, promoter methylation studies, in vitro translation, cDNA arrays].

- Evaluation of estrogenic or X chromosome-mediated effects on disease susceptibility, disease progression or response to treatment.

- Generation of nanoparticles encapsulating miRNA-, lncRNA-, gene-, or protein-targeting therapeutics (e.g. locked nucleic acid-based oligos, siRNAs, peptides/proteins) to treat the inflammatory or other manifestations of disease.

- Characterisation of the toxicity and efficacy of these drugs in in vitro cell models and iPSCs (induced pluripotent stem cells) by specialised single target [qPCR, ELISA, Western Immunoblotting, Confocal Microscopy, Flow Cytometry] and high throughput methodologies [Mesoscale Discovery arrays, High Content Analysis, Mass Spectrometry].

- Evaluation of a drug's nebulisation compatibility and airway deposition properties via cascade impactor and breathing mannequin studies.
