Preferably a physicist, but can be from a related field (such as physical chemistry). Preference will be given to candidates with experience in optics, particularly non-linear optics. A successful candidate will be designing and implementing optical microscopy experiments for various biological applications using non-linear optical phenomena such as two photon fluorescence, second harmonic generation and others. The experiments will be carried out on a unique, highly customizable laser scanning microscope equipped with a variety of light sources. Depending on the candidate, a high degree of scientific guidance or high amount of freedom will be provided.
