A postion for a PhD student is available in the field of "Processing and
integration of extracellular signals in the green alga Chlamydomonas
The thesis will be funded by the DFG (tentative start:
February 2000). The research project will focus on the question how
extracellular signals of different quality and duration are percepted and
integrated within a unicellular eucaryote. The signals of choice are:
green light signals percepted by the phototaxis photoreceptor
chlamyrhodopsin, blue light signals percepted by the cry1 homolog
receptor CPH1; a contact with the opposite mating partner, and finally,
rapid changes of extracellular pH and Ca2+, which leads to flagella
The main focuss of the work will be to study photocurrents and local
intracellular Ca2+ and pH changes by using electrophysiology and
fluorescence imaging. Several mutants with known molecular defects are

The successful candidate is trained in biology and/or biochemistry and
has a strong interest in a biophysical characterisation of the wildly
used plant model organism.
Experience with electrophysiological methods would be a plus.
