The Leibniz Institute of Freshwater Ecology (IGB) and the Leibniz Institute for Zoo and Wildlife Research (IZW) under the umbrella of the Forschungsverbund Berlin e. V. are both members of the Leibniz Association. “Research for the future of our freshwaters” is the mission of the IGB. It is Germany’s largest and one of the leading international research centers for freshwaters and seeks to understand the fundamental processes governing freshwaters and their biotic communities. The IGB’s research findings help to tackle global environmental changes and to develop measures for sustainable water management. The IGB is a diverse and inspiring place to work and conduct research. It promotes individual development at every career level and stands for lively exchange and cooperation. The Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in the Forschungsverbund Berlin e.V., a part of the Leibniz Association, aims to understand and, where possible, ‘improve’ the adaptive capacity of wild animals to cope with global change. To this end, it focuses on the diversity of lifestyles, diseases and mechanisms of evolutionary adaptation of mammals and birds, on the limits of these mechanisms in natural and anthropogenically influenced environments, and on conservation strategies that take these into account. The Institute fulfils this mission through long-term, application-oriented, interdisciplinary basic research in evolutionary ecology, ecological dynamics, evolutionary genetics, wildlife diseases, reproductive biology and reproductive management. The departments Experimental Limnology (IGB) and Wildlife Diseases (IZW) invite applications for the position of a Doctoral/PhD student (65%) to obtain Doctorate IGB, IZW, (Leibniz-Institut für Agrartechnik und Bioökonomie) ATB, Bernhard-Nocht-Institut für Topenmedizien (BNITM), Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ), (Forschungszentrum Borstel, Leibniz Lungenzentrum) FZB and Leibniz-Institut für Naturstoff-Forschung und Infektionsbiologie - Hans-Knöll-Institut (HKI) are members of the Leibniz Research Alliance “INFECTIONS” ( https://leibnizinfections.de/ ). The aim of this research alliance is to establish a culture of interdisciplinary research and communication across disciplines in order to develop new strategies and methods for early warning systems, improve outbreak management and optimize containment of the spread of antimicrobial resistance (AMR) pathogens. The research is based on the One Health approach taking into account the interaction of humans, animals and the environment. All research is conducted as collaborative projects between several partner institutes. The research project is part of the Leibniz Alliance Project Infections, which investigates the diversity and transmission of antimicrobial resistance (AMR). We are facing a near future in which antibiotic treatment to control bacterial and fungal infections will no longer be possible, throwing us back to the pre-penicillin era. In order to prevent this from happening, it is essential to understand the environmental AMR and identify methods for remediation. The candidate will assess the risk of human contact with AMR through environmental water by leveraging our accumulated data from INFECTIONS in the previous funding period and performing bioinformatics comparison with sequences of clinical isolates in our collections. Analyses will be extended to fungal pathogens, including mobile genetic elements. Future water collection will comprise waste water sampled in partner countries where antibiotics/antifungals are used in agriculture. The phage content of the samples (phageome, genomes of the phage population) will be determined to identify candidate phages to test in wastewater remediation pilot laboratory experiments. Responsibilities include: Collection and characterization of water samples in urban and rural environments for new samples obtained in this phase of the projects Preparation of DNA and RNA from water and sediments Preparation of high-throughput sequencing libraries Bioinformatic sequence analysis Determination of physical, chemical and biological environmental variables Statistical analysis of the generated data Requirements: Master’s degree in biology or microbiology Preference will be given to individuals with experience in molecular biology, especially high-throughput sequencing and/or bioinformatic analysis Experience in field sampling Good command of English and German, spoken and written Basic experience with statistics and R is an advantage Knowledge of programming languages such as Python and writing computer scripts is advantageous Our offer: An interesting and responsible position with room for manoeuvre in an international and dynamic scientific working environment, in a beautiful location right next to the Tierpark Berlin-Friedrichsfelde and next to the Lake Mueggelsee in Berlin-Friedrichshagen. place of work are State-of-the-art laboratories at all partner institutes.
