Post-Doctoral Career Development Fellow and Prostate Cancer Foundation Young Investigator.
My principal research interests lie in the field of small RNA and post-transcriptional regulation of gene expression in human disease. Specifically, I am interested in the mechanisms through which microRNAs ‘fine tune’ gene regulation, and how aberrations in these networks may contribute to disease. I am particularly intrigued by the regulatory mechanisms that govern microRNA biosynthesis, and by the huge potential of microRNA inhibitors/mimics to act as novel therapeutics in a wide array of conditions. Further interests include: microRNA ‘signatures’ as diagnostic or prognostic biomarkers, microRNA: long non-coding RNA (lncRNA) interaction networks, regulation of gene activity through alternative polyadenylation and RNA modifications, exosomal RNA-mediated communication mechanisms, and interplay between non-coding RNAs, nuclear receptors and DNA damage in cancer.
