Two fully funded PhD candidate positions in Electromicrobiology (3 years)

Two fully funded PhD candidate positions in Electromicrobiology (3 years)
We invite applications for two 3-year PhD student positions in the team of Professor Amelia-Elena Rotaru at the University of Southern Denmark. The PhD candidates will be supervised by Dr. Rhitu Kotoky and Dr. Konstantinos Anestis in close collaboration with Prof. Amelia-Elena Rotaru.

The two PhD projects will address complementary aspects of how electric fields and electrode-associated niches influence the structure function and stability of methanogenic microbial communities in bioelectrochemical reactors. Together the projects combine classical microbiology microbial physiology experimental evolution and omics-based approaches to link microbial interactions and system performance across spatial and functional scales.

PhD position in adaptive responses of defined methanogenic communities (3 years)
This position centers on defined syntrophic microbial consortia mapping how controlled electrochemical environments shape metabolic interactions electron-transfer strategies and functional specialization. You will run targeted experiments with defined methanogenic communities compare ancestral and evolved consortia across conditions and integrate phenotypic readouts with functional omics to identify the processes underlying key performance changes. You will work closely with a postdoc evolving these consortia and with collaborators developing genome-scale and process-level models.

PhD position in adaptive responses of complex methanogenic microbiomes (3 years)
This position centers on complex microbial communities derived from anaerobic digestion systems investigating how electrochemical environments drive community re-assembly population dynamics and functional resilience. You will follow changes in community composition and function across conditions connect these shifts to reactor-level phenotypes and contribute to omics-enabled analyses that identify key taxa and functions linked to performance and stability. You will work closely with a postdoc evolving these microbiomes and with collaborators developing genome-scale and process-level models.

Your tasks will be:
-setting up operating and monitoring bioelectrochemical reactors
-mapping microbial distributions across reactor niches
-functional omics and targeted assays for key taxa/functions
-establish standards of practice in collaboration with staff scientists in the team
-publish scientific articles based on the data you generate
-present research findings at research meetings and conferences

Your profile:
We seek candidates with:
-a relevant MSc degree in environmental microbiology molecular ecology microbiology biochemistry or a closely related field
-an excellent academic track record
-a strong commitment to sustainable technology developments
-interest in interdisciplinary research
-ability to write and communicate professionally in English
-ability to collaborate tightly within a multidisciplinary consortium and across career stages

Starting date: April 1st 2026 or soon after.

Applicants seeking further information can contact: Dr. Konstantinos Anestis (anestis@) Dr. Rhitu Kotoky (kotoky@) or Prof. Amelia-Elena Rotaru arotaru@

Who are we
The successful candidates will be employed at the Department of Biology (200 people) and embedded in the Nordcee research section (60 people) an interdisciplinary environment spanning environmental microbiology biogeochemistry microbial ecology and Earthlife interactions. Nordcee hosts a strong international research community with shared laboratory infrastructure and permanent administrative and technical support.

The positions will be hosted by the Rotaru Lab which studies electromicrobiology microbial syntrophy and microbemineral/electrode interactions with a particular focus on methane-cycling microorganisms and the development of sustainable bioelectrochemical technologies.

The positions are part of the Microbial Electrochemical Methanation Initiative a large collaborative research program funded by the Novo Nordisk Foundation (50 million DKK) with academic partners at DTU Biosustain Aarhus University (CORC and Biology) Toulouse Biotechnology Institute and Wageningen University as well as industry partners.

We recommend that as an international applicant you take the time to visit Work in Denmarkwhere you will find information and facts about moving to working and living in Denmark as well as the International Staff Office at SDU.
