PhD Position in Ecology (VU University of Amsterdam)

Are you interested in phages and microbial communities, and looking for a PhD position that combines cutting edge experimental and computational techniques? The Gralka and Mulla groups (A-LIFE & AIMMS, VU Amsterdam) are recruiting for a fully-funded 4-year PhD position. Ideal candidates should have an interest in fundamental questions in microbiology and microbial ecology. Location: AMSTERDAM FTE: 1 - 1 Job description Microbial communities are essential to the functioning of ecosystems, from the oceans to the human gut. Within these communities, phages infect vast numbers of bacteria every day and outnumber bacteria about 10 to 1. Currently, we lack a quantitative understanding for how phages impact community composition and function, and conversely, how a complex community context shapes the action of phages on their specific hosts. In this PhD project, you will study marine bacteria and their phages in isolation and in communities, from simple synthetic communities to enrichments of natural communities. Combining high-throughput characterization methods and state-of-the-art bioreactor technology with metagenomic sequencing and mathematical modelling, your research will lead to a quantitative understanding of the effects of phages on microbial communities and the ecosystem functions they provide. Beyond a better understanding of phage-bacteria interactions in marine microbial communities, this project will also yield insights and methods that will be applicable to other environments such as soils and industrially relevant communities (wastewater treatment, food microbiology), as well as for phage therapy to treat antibiotic resistant bacterial infections. Your duties create and quantitatively characterize a phage bank for key marine bacteria measure the effects of phage infection in different community and environmental contexts obtain and analyze amplicon and metagenomic sequencing data optional: construct mathematical (kinetic) models of phage-bacteria interactions in complex communities assist in teaching, including the supervision of BSc and MSc internship students communicate your research in local and international conferences write a dissertation leading to a PhD degree towards the end of the 4-year project Requirements This project is highly interdisciplinary; ideal candidates should have a subset of the required skills (microbiological/phage laboratory skills, programming, modelling, bioinformatics) and a strong willingness to learn new skills. you have a MSc or equivalent degree in systems biology, (micro)biology, (bio)physics, or a similar field you have good experimental skills, and preferably experience with basic microbiological laboratory skills you have experience with programming (e.g., Python, Mathematica or R) excellent ability to communicate in both spoken and written English What are we offering?

Job description

Microbial communities are essential to the functioning of ecosystems, from the oceans to the human gut. Within these communities, phages infect vast numbers of bacteria every day and outnumber bacteria about 10 to 1. Currently, we lack a quantitative understanding for how phages impact community composition and function, and conversely, how a complex community context shapes the action of phages on their specific hosts.

In this PhD project, you will study marine bacteria and their phages in isolation and in communities, from simple synthetic communities to enrichments of natural communities.

measure the effects of phage infection in different community and environmental contexts
obtain and analyze amplicon and metagenomic sequencing data
optional: construct mathematical (kinetic) models of phage-bacteria interactions in complex communities
assist in teaching, including the supervision of BSc and MSc internship students
communicate your research in local and international conferences
write a dissertation leading to a PhD degree towards the end of the 4-year project

Requirements

This project is highly interdisciplinary; ideal candidates should have a subset of the required skills (microbiological/phage laboratory skills, programming, modelling, bioinformatics) and a strong willingness to learn new skills.

you have a MSc or equivalent degree in systems biology, (micro)biology, (bio)physics, or a similar field
