My work constitutes an expert service to the community, i.e. Paternity Testing. These investigations are mostly referred to me by the maintenance courts or attorneys, although private appointments are also accepted. Currently we perform tests on 300-350 trios per year. The analysis of paternity is done by means of an investigation of repetitive regions (Short Tandem Repeats or STRs) that are found on DNA. These STRs are amplified using the PCR reaction and primers marked with fluorescent dyes. Electrophoresis follows on a DNA Genetic Analyser and the data is analysed with special software. I am regularly called upon to serve as an expert witness in court cases concerning maintenance. I also run an External Quality Assurance programme, PAPPA (Proficiency Assessment Programme for Paternity Analysis) for paternity testing from Bloemfontein. Currently there are eight South Afican laboratories that take part.

Furthermore we provide a service to researchers who are involved in DNA sequencing and AFLP analyses.

I am the head of the section which does Histocompatibility Testing for transplantation purposes as well as disease association studies. We also test for DNA mutations involved in disease (e.g. Faktor V Leiden, Prothrombin, MTHFR and JAK2 mutations).

My research interest at the moment is to investigate mutations and other factors that are involved in Myeloproliferative Neoplasms.
