Research Interests

I have been using a custom spotted oligo microarray platform to investigate gene expression signatures in autoimmune diseases, specifically ANCA-associated systemic vasculitis and SLE. The highly heterogeneous clinical phenotypes seen in these syndromes make classification and diagnosis problematic and potentially confound attempts to further investigate underlying pathogenesis.

I am using a cell separation step in RNA extraction from whole blood to derive labelled cDNA from 5 cell subsets (CD4,8,14,16 and 19) as well as unseparated PBMC. Samples are collected during active disease and subsequently after 3 and 12 months of therapy, during which time patients undergo close clinical monitoring. This allows correlation of derived expression signatures with extensive clinical data and mining for novel disease biomarkers with both diagnostic and prognostic value.
