The M.Sc. OEP-Biology is a research-oriented, international study programme taught in English, which aims at providing students with a broad understanding of all aspects of Organismic Biology. Evolutionary biology and biodiversity research connect various disciplines such as Systematics, Phylogeny, Palaeobiology, Physiology, Ecology, Molecular Biology, Ethology and many more. Strong emphasis is given to practical research experience in the field and in the laboratories of the participating research groups and in the large collections of the Zoological Museum Alexander Koenig, the Goldfuß-Muse­um of Palaeontology and the Botanical gardens of the University of Bonn. Teaching in OEP-Biology is theory-oriented aiming at enabling students to think critically, analytically and strategically.
