Research projects: Enzyme characterization and engineering / Virome studies / Discovery of bioactive marine natural products

I was born in Walvisbay (Namibia) in 1978. After completing high school in Windhoek (Namibia) I moved to Stellenbosch (South Africa) to further my studies. Here I discovered my passion for all things microbial, and in particular the molecular underpinnings of biology. Following completion of my M.Sc. in Microbiology in 2003, studying the mechanisms by which plasmids move from one bacterium to another, I took a break from studying to work in a research lab and hone my skills. After moving to the University of the Western Cape (UWC) in mid-2008 I continued working as a research assistant until the realization that I am an academic at heart and with this came the decision to do my PhD. I attained my doctoral degree (http://etd.uwc.ac.za/xmlui/handle/11394/5845) at the beginning of 2018 and since April of 2018 I have been the manager of the single cell genomics and flow cytometry platform at UWC. Along the way I’ve worked on a wide variety of topics covering enzymology and enzyme engineering, molecular ecology, metabolic engineering, bacteriophage characterization, genomics and more.
