Louis du Preez

Du Preez grew up in Ficksburg and started his tertiary education at the University of the Free State located in the same province he was brought up. In 1986 he obtained his Master of Science degree with the thesis titled 'Polystoma australis (Monogenea): aspekte van ontwikkeling en gedrag wat betrekking het op rekrutering en vestiging'.

From 1989 to 1990 he was a school teacher in Bloemfontein. From 1991 to 1993 he was Head of the Department of Herpetology at the National Museum in Bloemfontein. In 1994 he obtained a PhD degree from the University of the Free State with a thesis titled 'Study of factors influencing the nature and extent of host-specificity among polystomatids (Polystomatidae: Monogenoidea) parasitic in Anura of southern Africa' under the mentorship of Dawid Kok. Du Preez then progressed to being the Senior Lecturer of Zoology at the University of the Free State from 1996 to 2000. From 2001 to 2004 he was appointed associate professor. In 2002 he established the African Amphibian Research Conservation Group and was later promoted Full Professor of Zoology in 2005 at North-West University. In 2011 du Preez was elected Chair of the Zoology Department at North-West University.

Throughout his career he has conducted research in several countries across the world including France, United States, Nigeria, Brazil and China. He is a member of the Zoological Society of Southern Africa, the Herpetological Association of Africa, the Suid-Afrikaanse Akademie vir Wetenskap en Kuns, the Parasitological Association of Southern Africa and the Microscopy Association of Africa.

Louis du Preez published several books and over 100 scientific articles. In addition to several parasite, frog, and reptile species that are new to science, du Preez's species descriptions include the frog species Breviceps carruthersi and Breviceps passmorei from the Rain Frog family (Brevicipitidae), and Hyperolius howelli from the Reed Frog family (Hyperoliidae).
