Martin Geier completed his diploma (equiv. master's, 1991) and doctoral thesis (1995) on the olfactory host finding behaviour of the yellowfever mosquito Aedes aegypti in Regensburg. He was a post-doc at the Department of Entomology at the University of California in Riverside and after his return to Germany 1998 head of the mosquito research group at the University of Regensburg. His main research area is the sensory and chemical ecology of blood sucking insects. Research topics are: 1) the encoding of odour components, on which mosquitoes identify and find a human host and 2) the underlying sensory and orientation mechanisms, which enable mosquitoes to differentiate between different host species and to locate their hosts. This fundamental research led to an application in the public health domain of vector transmitted diseases such as Malaria, Dengue- and Yellow fever. Together with a Brazilian research group he develops new tools and methods for monitoring mosquito disease vectors. This helps to reduce the use of insecticides. Together with his partner Andreas Rose he founded a spin off from the University of Regensburg, the BioGents GmbH. This research company offers testing, evaluation and development of specific attractants and repellents for the use of environmental friendly control of insect pests.
