short cv

·           peter   maienfisch is the owner of creinsol mcb, a company formed in april 2020.   previously he held the role as research portfolio manager insect control   & seedcare at syngenta crop protection ag in switzerland (until april   2020). in this role he was responsible to define the research strategies and   to govern all insecticide, nematicide and seedcare research projects across   technologies from their initiation to the delivery to development.

·           furthermore,   he works as honorary professor at the east china university of science and   technology (ecust), shanghai, china, and as lecturer at the university of   basel, switzerland.

·           peter   maienfisch studied chemistry at the swiss federal institute of technology   (eth) in zürich, switzerland, where he received his phd in 1983. afterwards   he spent almost 2 years at the california institute of   technology (caltech; pasadena, ca, usa) to perform post-doctoral research in   the group of robert e. ireland.

·           during his   career he held several different leadership functions in crop protection   r&d including group leader insecticide chemistry, analytics &   automation at syngenta, head of chemistry in crop protection research at   novartis and group leader in insecticide research at ciba.

·           his track   record of innovation and successful introduction of new technologies includes   authorship of more than 200 scientific papers and patents. he is the inventor   of thiamethoxam (actara®, cruiser®, one of the leading insecticides   world-wide with annual sales of more than 1 billion $), and championed the development   of this innovative insecticide. furthermore, he initiated research on many   new chemical classes at syngenta and made essential contributions to the   discovery and optimization of several new active ingredients, such as   spiropidion, isocycloseram, cyclobutrifluram and a malaria vector control   compound, which are expected to reach the market in the next couple of years.   his scientific contributions also led to many invitations as a speaker and   co-organizer of many international congresses, including iupac crop   protection congresses.
