The Ecosystems and Global Change Group led by Dr Andrew Tanentzap at the University of Cambridge ( is seeking a full-time Research Laboratory Technician in Microbial Evolution. The Technician will join an exciting new project funded by the European Research Council investigating the ecological and evolutionary importance of molecular diversity in dissolved organic matter (DOM).

The main objective of the position is to support the daily operation of a long-term evolution experiment. This experiment aims to test how a model bacterium (Pseudomonas fluorescens) adapts under different biogeochemical conditions created by different DOM sources and with competing Proteobacteria. More broadly, this experiment will answer questions about the repeatability and pace of evolutionary adaptation and how evolutionary responses vary with ecological interactions.

The Technician will initially be responsible for optimising the experimental design (e.g. inoculum density, growing conditions, competitor renewal), with the bulk of the position spent maintaining the experimental cultures, carrying out daily transfers into fresh media, and regularly preserving colonies. Media will be amended with DOM sourced from different European lakes, and the Technician will have the opportunity to visit these lakes to collect appropriate water samples. The Technician will also run regular competition assays to assess the relative fitness of preserved colonies. Finally, the Technician will be expected to maintain and operate laboratory equipment and support student and postdoctoral research.

The successful candidate must have considerable experience in bacterial culture techniques and media. They will ideally have an undergraduate degree in the Biological Sciences, preferably microbiology or related. Experience with molecular biology, water chemistry, and/or field work is desirable, but not necessary.

Fixed-term: The funds for this post are available for 3 years in the first instance.

Once an offer of employment has been accepted, the successful candidate will be required to undergo a health assessment.
