Postdoctoral Researchers (W20116)


Molecular Spectroscopy Laboratory
RIKEN Cluster for Pioneering Research
(Team Leader: Tahei Tahara)

Research Field

This laboratory develops and utilizes the most advanced spectroscopy for molecular science of fundamental and complex systems in the condensed phase. To elucidate a variety of complex phenomena occurring in the condensed phase, we clarify the electronic and vibrational states of molecules, the response of surroundings, and the fluctuation and dissipation of energy behind. Based on this view, we carry out fundamental research using the most advanced linear/nonlinear spectroscopic methods with most suitable time- and space-resolution for the problems to be studied.

Job title and Job description

Job title, available positions

Postdoctoral Researcher: 1-2 positions
Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less.

Job description

The position conducts research in one of the following three categories:

  • 1.Study of complex molecular systems by ultrafast spectroscopy
  • 2.Study of interfacial phenomena by nonlinear spectroscopy
  • 3.Study of biomolecules by single molecule spectroscopy


The candidate should possess a doctoral degree (or should be expected to have a doctoral degree before the starting date) in a related research field.  Experience on molecular science using advanced spectroscopy will be advantageous. In particular, young researchers willing to carry out challenging research on interfaces using ultrashort lasers are most welcome.
