Westerdijk Award

The KNVM/NVMM science committee awards up to three prizes for the best PhD-thesis, one each in the categories "general microbiology", "medical microbiology", or "microbial ecology". Candidates, whom are society members, should submit their PhD-thesis on condition that it was defended less than a year ago. The prizes, which were first awarded in 2009, are named after Johanna Westerdijk. She was appointed professor at the University of Utrecht in 1917 and was the first female professor in the Netherlands. She was director of the phytopathology laboratory Willie Commelin Scholten and showed that the elm disease (generally known as dutch elm disease) was caused by the fungus Ceratocystis ulmi. The prizes (EUR 1000) are annualy awarded during the KNVM/NVMM Scientific Spring Meeting. The jury consists of members of the KNVM/NVMM science committee. Please send three copies of your thesis and your data to:
