Apply
Are you a toxicologist or microbiologist passionate about environmental research for the protection of human health and the environment? Please apply at Vrije Universiteit Amsterdam.

Your function

Antimicrobial resistance (AMR) is increasing morbidity, mortality, and health-care expenditures worldwide. The (semi-)natural aquatic environment functions as an important reservoir and dissemination route of antimicrobial resistance genes (ARGs), where bacteria carrying these ARGs can proliferate in the presence of antibiotic residues and other antimicrobially active chemicals. In this context, in vitro and in silico methodologies are needed to support aquatic AMR surveillance and chemical risk assessment practice.

The Vrije Universiteit (VU) Amsterdam seeks a highly motivated and talented candidate holding a PhD degree in (eco)toxicology, microbiology, analytical chemistry or a related field, to join our Amsterdam Institute for Life and Environment (A-LIFE). During this 22-month full-time postdoctoral position, you will contribute to two research projects related to the environmental dimension of the urgent global health threat that is AMR. Your main focus will be on the development of an in vitro bioassay for AMR selection potential of water samples, as part of the NOSTRA project (Novel Surveillance Toolkit for Resistance selection potential of Antimicrobially active waters). You will also use your experimental results to develop an in silico mechanistic model of the relationship between antibiotic exposures and AMR selection. A smaller part of this position contributes to the SWIM project (Safe drinking Water production from AMR polluted surface water using Innovative Membrane technology). As part of SWIM, you will perform an environmental and a human health AMR impact assessment, based on a pilot study on improved water treatment in Jakarta (Indonesia).

We are looking for someone holding a PhD with a strong experimental background in (eco)toxicology and/or microbiology, with experience in in vitro toxicity testing, preferably with bacterial culturing techniques. Moreover, the candidate has demonstrable experience with translating experimental findings into computational in silico models and assessments, using R, Python, or more advanced programming languages. As the research crosses multiple research domains within and beyond A-LIFE, we are looking for someone who flourishes working in a team and enjoys building bridges between experts from different disciplines.

Your duties

  • Develop bioassay by applying molecular techniques such as cloning, expression of fluorescent proteins in bacteria, cell sorting;
  • Run in vitro bioassays on water samples;
  • Mechanistic modelling of chemical toxicokinetics and -dynamics;
  • AMR and antibiotics impact assessments for local Jakarta population and environment.

Your profile

  • PhD in (eco)toxicology with microbiological affinity, or PhD in microbiology with (eco)toxicological affinity;
  • Knowledge of, and experience with, molecular techniques such as transformations, cloning, cell sorting;
  • Affinity with in vitro toxicity testing, preferably with bacterial culturing techniques;
  • Extensive experience in (mechanistic) biological and chemical modelling;
  • Ability to work independently and in collaboration with others;
  • Strong oral and written communication skills in English.

What do we offer?

A challenging position in a socially engaged organisation. At VU Amsterdam, you contribute to education, research and service for a better world. And that is valuable. So in return for your efforts, we offer you:

  • a salary of minimum € 4.185,00 (Scale 10.05) and maximum € 4.492,00 (Scale 10.07) gross per month, on a full-time basis. This is based on UFO profile Researcher 4. The exact salary depends on your education and experience.
  • a position for at least 0.8 FTE. Your employment contract will initially last 22 months.   

We also offer you attractive fringe benefits and regulations. Some examples:

  • A full-time 38-hour working week comes with a holiday leave entitlement of 232 hours per year. If you choose to work 40 hours, you have 96 extra holiday leave hours on an annual basis. For part-timers, this is calculated pro rata.
  • 8% holiday allowance and 8.3% end-of-year bonus
  • a wide range of sports facilities which staff may use at a modest charge
  • optional model for designing a personalized benefits package
  • contribution to commuting expenses

About us

A-LIFE
The vacancy is embedded in the section Chemistry for Environment and Health of the Amsterdam Institute for Life and Environment (A-LIFE) in the Faculty of Science of the Vrije Universiteit Amsterdam. A-LIFE brings together the former departments of Environment & Health, Molecular Cell Biology and Ecological Sciences. A-LIFE seeks to connect properties and emerging behaviours across all scales, from molecules to ecosystems, including human populations. The section Chemistry for Environment and Health investigates environmental and human exposure, focusing on the development and application of advanced analytical methods for accurate, robust exposure of the assessment to a wide variety of chemicals, and including, PFAS, micro- and nanoplastics, and pharmaceuticals.

Faculty of Science
Researchers and students at VU Amsterdam’s Faculty of Science tackle fundamental and complex scientific problems to help pave the way for a sustainable and healthy future. From forest fires to big data, from obesity to malnutrition, and from molecules to the moon: we cover the full spectrum of the natural sciences. Our teaching and research have a strong experimentally technical, computational and interdisciplinary nature.

We work on new solutions guided by value-driven, interdisciplinary methodologies. We are committed to research, valorisation and training socially engaged citizens of the world who will make valuable contributions to a sustainable, healthy future.

Are you interested in joining the Faculty of Science? You will join undergraduate students, PhD candidates and researchers at the biggest sciences faculty in the Netherlands. You will combine a professional focus with a broad view of the world. We are proud of our collegial working climate, characterised by committed staff, a pragmatic attitude and engagement in the larger whole. The faculty is home to over 11,000 students enrolled in 40 study programmes. It employs over 1,600 professionals spread across 10 academic departments.
