PhD candidate, Department of Genetics, Faculty of Natural and Agricultural Sciences
University of the Free State

Louis S. Le Clercq is a SACNASP registered Molecular Biologist, with a Bachelors of Science (B.Sc.) from the University of Pretoria. Thereafter they completed a B.Sc. Honors as well as a research based Masters of Science (M.Sc) as further post-graduate specialization. This was followed by an internship/stage by the DST-NRF at SANBI. They are currently doing thesis research towards a Ph.D. degree in Genetics at UFS with a focus on molecular clocks and migration, and biological clocks and age.
