My research interests centre on small molecule measurements and metabolomics in plants and thus span the fields of plant biology, chemistry, and bioinformatics. My activities focus on novel method development and integration between these fields and are tailored to underpin gene and pathway discovery in plant functional genomics. My expertise is in the development of screening pipelines for small molecule extraction, isolation and derivatization where necessary, chromatographic separation (liquid and gas chromatography), and detection including (but not limited to) mass spectrometry. I also write novel algorithms in R to facilitate mining complex metabolomics data.
