Marian Tredoux is a South African with science degrees from 3 different South African Universities (Stellenbosch, UCT and University of Witwatersrand). She has worked as an analytical chemist in the mining/ beneficiation industry. She has spent significant parts of her research time at leading overseas universities. Her research interests focus primarily at the geochemistry of the platinum group elements which she uses as tracers to study a broad spectrum of geological, archaeological and planetary problems: meteorites, core formation, platinum ores and major extinction events in the biological record. 7	Marian Tredoux mtd@geology.uct.ac.za	Most of her interest in this field centres on teaching and learning at tertiary institutions, especially in the context of addressing the problems of educationally disadvantaged students. The development of materials for use in schools, and ways to improve the Earth Science awareness of all school-going children, are also seen as important issues. She has travelled widely to liaise with colleagues about these matters throughout Africa and overseas. Marian is presently employed as a senior lecturer through the Science Faculty at UCT as the Earth Science coordinator for Academic Support to students from disadvantaged backgrounds; she is a founder of this program with 12 years experience in corrective action in geoscience education in Africa.
	She is also involved in geoforesic work related to illegal ivory and rhino horn trading. Another important branch of her research interest relates to geoscience education.
