I am working at the MRC Biostatistics Unit as a Research Associate under the supervision of Dr Leonardo Bottolo and Prof. Sylvia Richardson. In my research at BSU I am investigating the use of high dimensional metabolomic data for accurate discrimination between rare disease types, as well as for improving diagnosis and therapeutic intervention. Prior to coming to BSU, I completed my PhD in consultation with Prof. Petros Dellaportas (Department of Statistical Science, University College of London) and Prof. Omiros Papaspiliopoulos (Department of Economics and Business, University at Pompeu Fabra in Barcelona). In my doctoral dissertation, I combined the use of existing and the development of new statistical methods to carry out Bayesian inference in stochastic models designed for high dimensional data.
