PhD Candidate in Anaerobic Microbiology (1.0 FTE)

Updated: about 2 months ago

  • Employment: 1.0 FTE

  • Faculty of Science
  • Required background: Research University Degree
  • Application deadline: 9 December 2021

Are you a microbiologist looking to start your academic career off right? Then help us investigate the metabolism of the diverse group of anaerobic microorganisms as a PhD candidate. As methanotrophic microorganisms function as a powerful methane filter in many ecosystems, your research into their physiology and biochemistry might even lead to new insights surrounding climate change.

There is an enormous untapped potential within the functionally diverse group of anaerobic microorganisms. Anaerobes are responsible for the turnover of a large part of macro- and microelements, and they are vital for all biogeochemical cycles. Within the methane cycle, anaerobic methanotrophic archaea are responsible for the oxidation of methane in the absence of oxygen. Methane is the second most abundant greenhouse gas, and it contributes considerably to climate change. Methanotrophic microorganisms function as a powerful methane filter in many ecosystems. In the past ten years, new central metabolic pathways in this important group of microorganisms have been described. However, still relatively little is known about their physiology and biochemistry. In this project, you will study different aspects of the physiology and biochemistry of anaerobic methanotrophs (ANME). The project is part of the SIAM Gravitation Programme. You will have a teaching load of up to 10%.

  • You hold a Master's degree in life sciences (biology, microbiology, biotechnology, molecular life sciences or a related area) with a focus on microbiology.
  • You have proficiency in English, both written and spoken.
  • You have good communication skills and the ability to operate in a dynamic international research team.
  • You are willing and able to develop yourself to become an independent scientist (growth mindset).
  • Knowledge of basic microbiological methods is essential.
  • Experience with anaerobic microbiology techniques (batch and bioreactor cultivation use of anaerobic hood) and in biochemistry (e.g. gained during a course or research project) would be an advantage.

We are

The Microbiology cluster is world-leading in environmental microbiology and has won many prestigious awards including three ERC Advanced Grants, an ERC synergy grant, a Spinoza Prize and two Gravitation Grants. The Microbiology cluster is embedded in the Radboud Institute for Biological and Environmental Sciences (RIBES), Faculty of Science, Radboud University. We offer a dynamic research environment with a strong international profile, state-of-the-art laboratory infrastructure, strong national and international collaborations, and the opportunity to further develop yourself both scientifically and professionally by participating in a large variety of courses, training and conferences.

Radboud University
We want to get the best out of science, others and ourselves. Why? Because this is what the world around us desperately needs. Leading research and education make an indispensable contribution to a healthy, free world with equal opportunities for all. This is what unites the more than 24,000 students and 5,600 employees at Radboud University. And this requires even more talent, collaboration and lifelong learning. You have a part to play!

We offer
  • Employment for 1.0 FTE.
  • The gross monthly salary amounts to €2,434 based on a 38-hour working week, and will increase to €3,111 in the fourth year  (salary scale P ).
  • You will receive 8% holiday allowance and 8.3% end-of-year bonus.
  • You will be appointed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years (4 year contract).
  • You will be able to use our Dual Career and Family Care Services . Our Dual Career and Family Care Officer can assist you with family-related support, help your partner or spouse prepare for the local labour market, provide customized support in their search for employment  and help your family settle in Nijmegen.
