I am a postdoctoral research chemometrician at the MRC-NIHR Phenome Centre, a world-class facility for the metabolic phenotyping of human samples. Here, I contribute to quality-control assessment, method development and biomarker discovery and validation in patient- and population-based samples with the overarching aim of discovering robust diagnostic and prognostic markers for disease risk and personalized medicine.
As such, my main research interests include: (1) elucidating the complex relationship between health status, diet, genetics, drugs, microbiome and environment in metabolic phenotyping based analysis of patients and populations (2) development of statistical methods for enhanced information recovery from spectroscopic data.
(1) Elucidating METABOLIC relationships
For example, investigating the microbial influences on metabolism.
(2) Development of Statistical Methods for Spectroscopic Data Analysis
For example, utilizing the inherent correlations between spectral variables in order to:
- Identify, deconvolve and selectively remove drug metabolite signals from NMR data
- Explore inter- and intra-metabolite connectivities
