Dr. Markus Geisler

Biography

In 1996, Markus Geisler completed doctoral work at Heinrich-Heine University Düsseldorf in Germany, characterizing atypical cyanobacterial Ca-ATPase in the cyanobacterium, Synechocystis PCC 6803. He undertook postdoctoral stays with Mickey B. Palmgren at the University of Copenhagen from 1996 to 1998 and Enrico Martinoia at the University of Neuchâtel from 1999 to 2002, focusing on type IIB Ca-ATPases PGP/ABCB and MRP/ABCC-like ABC transporters in Arabidopsis thaliana. From 2002 to 2010, he worked as a group leader in the lab of Enrico Martinoia at the Institute of Plant Biology, University of Zurich, where he established that members of the Arabidopsis ABCB/PGP family function as auxin transporters. He also discovered a novel mechanism for ABCB auxin transport regulation involving protein-protein interactions with immunophilin-like FKBP42 and TWISTED DWARF1. In 2011, he moved to the University of Fribourg, where his research now concentrates on the roles of ABCB/PGP auxin transporters in plant physiology, the regulation of their functional interactions, protein phosphorylation, and the effects of cytoskeleton-modulating drugs. He has held a permanent lecturer position since 2014.
