During the course of 1994 two postdoc positions will become
available in the biophysics group of prof. Rienk van Grondelle, concerning
optical spectroscopy research on photosynthetic light-harvesting complexes and
reaction centers from purple bacteria and green plants. Both positions
concern a period of approximately 2 years.
One of these positions has become available through funding by the
Human Capital and Mobility program of the European Community which implies
that only people from member countries or from so-called EFTA countries can
apply for this particular position. The corresponding research will be directed
at the study of complexes from the purple bacterium Rb. sphaeroides and
mutants therof with different spectroscopic methods including
1) time-resolved and 2) (quasi) steady-state techniques:
1) (sub)picosecond transient absorption spectroscopy (one-color, two-color,
continuum), fluorescence upconversion, photoncounting, nano-millisecond
transient absorption spectroscopy,
2) absorption, linear dichroism, circular dichroism, polarized fluorescence
and site-selection (polarized) fluorescence and triplet minus singlet
Measurements can be performed between 4 K and room temperature. High pressures
and high electric fields can be applied.
The spectroscopic techniques can be combined with advanced biochemical methods
for the purification of specific pigment-proteins. Facilities for biochemical
experiments are available.
The exact nature of the research will depend on the specific
interests of the post-doc.
The other position is not restricted to people from the above mentioned
countries. Use will be made of the mentioned techniques for the study of
photosynthetic light-harvesting complexes and reaction centers from
purple bacteria and green plants. The exact nature of the research will again
depend on the specific interests of the post-doc.
A background in (bio)physics or in (bio)physical (bio)chemistry is preferred
but also interested people with a different background are encouraged to
