Alexandra Tomerius (* 1970) studied Agricultural Sciences at the University of Hohenheim, where she did her doctorate in the group of Professor H.H. Geiger. She received her Ph.D. (Dr. sc. agr.) in 2001 with a thesis about "Optimization of seed-parent line development in hybrid rye breeding" employing software- supported model calculations. This work was carried out in close cooperation with the breeding companies Hybro GbR, Lochow-Petkus GmbH and Saatzucht Dr.h.c.Carsten Inh. E. Eger KG. After graduation, Dr. Tomerius further devoted herself to the optimization of plant breeding - first as a research associate and since 2007 as a freelancing consultant. Successful projects e.g. related to the optimization of breeding winter wheat (Client: Lochow-Petkus GmbH) as well as winter oil seed rape (Client: DSV Deutsche Saatveredelung, Lippstadt). Dr. Tomerius is an experienced lecturer in German and English. Starting from 2011, the provision of training courses for plant breeding companies and lecturing on plant breeding will form another essential part of her work. A new project is the development of teaching software for plant breeding in collaboration with the European Plant Breeding Academy (EPBA) of UC Davis, California. She is a regular lecturer for the EPBA classes.
