The Faculty of Science / the Institute for Biology and Naturalis Biodiversity Center are looking for a:

Lab Technician

Vacancy number: 21-691

Key responsibilities

The Wielstra lab studies the ultimate evolutionary enigma. Due to a ‘balanced lethal system’ exactly half of the developing embryos in the salamander genus Triturus (the crested and marbled newts) die inside their eggs. We want to know how such an incredibly maladaptive situation could ever evolve. One key question is: what goes wrong with the embryos that perish? Are particularly genes are malfunctioning? Your main task will be to optimize a protocol to extract both RNA and DNA from developing embryos, genotype these from the co-extracted DNA, and prepare libraries for RNA sequencing for those individuals that have a genotype of interest. You will also support the lab in general, e.g. by supervising students in the lab.

Selection Criteria

  • You hold a BSC or MSc in biology or a related field;
  • You are experienced in the lab;
  • You have experience with RNA extraction and library preparation;
  • You must be proficient in spoken and written English and have good communication skills;
  • You are a team player, but also able to work independently;
  • You are organized and have an interest in academic research;

Research at our faculty

The Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. It is a faculty where personal and academic development are top priorities. Our people are committed to expand fundamental knowledge by curiosity and to look beyond the borders of their own discipline; their aim is to benefit science, and to make a contribution to addressing the major societal challenges of the future.

The research carried out at the Faculty of Science is very diverse, ranging from mathematics, information science, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The research activities are organised in eight institutes. These institutes offer eight bachelor’s and twelve master’s programmes. The faculty has grown strongly in recent years and now has more than 2300 staff and almost 5000 students. We are located at the heart of Leiden’s Bio Science Park, one of Europe’s biggest science parks, where university and business life come together.

The Institute for Biology

The research within the Institute of Biology Leiden (IBL) aims to work on the science base of biodiversity and health, which is reflected in our leading principle Harnessing Biodiversity for Health. We perform innovative curiosity-driven research to answer fundamental questions, and solutions-driven research to help solving major societal challenges. The latter include protecting nature’s biodiversity, creating sustainable biotechnology and agriculture and increasing good health. Our research focuses on four Research Themes: Bioactive Molecules, Host-Microbe Interactions, Development & Disease and Evolution & Biodiversity. Located in a thriving scientific environment with our Faculty of Sciences,  Naturalis Biodiversity Centre, the Leiden University Medical Centre and the Leiden Bioscience Park, IBL offers an exciting, internationally oriented and inclusive place to work and study.

Naturalis Biodiversity Center

Naturalis Biodiversity Center in Leiden is the Dutch national research institute for biodiversity and systematics. With our collection of 42 million specimens, one of the world's largest natural history collections, and our state-of-the-art research facilities we offer the (inter)national research infrastructure for species, identification and monitoring. We closely collaborate with many Dutch universities, research institutes, industry and government. We host over 120 researchers including 13 academia embedded professors and 40 PhD students. We present the history of our planet, and the diversity of life on Earth, through permanent and temporary museum exhibitions, educational programmes and online presence, with more than 400,000 visitors per year. All in all, a unique combination of science and culture in the Netherlands and elsewhere in the world!
