Doctoral thesis "Studies on the molecular Genetics of tyrosinaemia type I" defended Oct 24th, 1995.
Main research interests are Inborn Errors of Metabolism (IEM), Genetic analyses primarily using DNA sequencing, in vitro mutagenesis and gene expression and allele detection using real time PCR analyses in relation to IEM, pharmacogenetics, cognitive function and melanomas and other disorders.
Main focus since 2014 is Metabolomics using Liquid Chromatography and High Resolution Mass Spectrometry analyses to establish a robust platform for research and diagnostics in IEM, Clincial Chemistry and in collaborative clinical studies with experts in the relevant fields.
