DC3: Discovery of novel flavin-dependent halogenases by functional annotation

ORGANISATION

Founded in the early sixties of the last century to address the challenges of structural change in the region, the Ruhr University Bochum (RUB) has developed into one of Germany's largest research universities (over 37,700 students distributed among 21 Faculties). It hosts the full spectrum of academic disciplines on its campus – the humanities and social sciences, the natural sciences and medicine as well as engineering. Collaborative research across traditional disciplinary boundaries, a university-wide Research School for early career researchers and knowledge networks at the local, regional, and international level highlight RUB's distinct institutional research profile. The position we offer will be embedded in the Microbial Biotechnology group (MBT, ) within the Faculty of Biology and Biotechnology (Faculty, ). Researchers at our Faculty perform interdisciplinary research in all fields of biology from a fundamental as well as from an applied point of view. Cross-discipline cooperations provide an exciting and inspiring environment which is complemented by state-of-the-art infrastructure such as mass spectrometry facility, imaging facility, the centre for protein diagnostics and the centre for system-based antibiotic research among other initiatives.

ROLES AND RESPONSIBILITIES

The main part of your PhD research (4 years in total) will be carried out at Ruhr University Bochum (RUB, Germany) under the supervision of Prof. Dr. Dirk Tischler in the Microbial Biotechnology group (MBT) at the Faculty of Biology and Biotechnology. Within these four years, an academic research stay (of 12 months) will take place at the University of Pavia (UniPV, Italy) under the supervision of Prof. Andrea Mattevi. Additionally, two industrial secondments at the companies BRAIN (Germany) and Provolut (Germany) are foreseen. The Horizon Europe Marie Skłodowska-Curie Actions (MSCA) – Doctoral Network (DN) project starts in January 2026. The date of recruitment and start of the PhD project is planned for April 2026 and latest in December 2026. Your PhD degree (so-called double degree) will be awarded based on successful completion of the research work from two universities (RUB, Germany and UniPV, Italy). You will also be required to participate in the training events and workshops organized by the DN- Joint Doctorates (JD) program. As a MSCA fellow, you are also expected to contribute your time in the dissemination of your PhD project's result through public engagement and other scientific platforms.

The PhD research will focus on:

• Interdisciplinary project on bioinformatics, enzymology, and biocatalysis,
• Computationally-guided enzyme mining and identification of novel flavin-dependent halogenases,
• Phylogenetic analyses and sequence-function predictions related to stability and substrate scope for guided protein engineering (industrial secondments),
• Cloning, expression, and elucidation of structure-function relations of selected candidates,
• Crystallization (incl. bioinformatic analysis and modelling) of selected candidates (academic secondment),
• Providing tailored catalysts for cascade development and applications

The RUB Research School served as a blueprint for the Research Academy Ruhr, which has been set up as a cross-university early career researcher ́s platform of the University Alliance Ruhr (UA Ruhr), our strategic alliance with the University of Duisburg-Essen and Technical University Dortmund. Around 10,000 young scientists benefit from the services of the RAR. As one of the largest platforms of its kind in Germany, the RAR offers advanced Master's students, doctoral students and postdocs up to junior professorships the opportunity to establish and expand cross-university networks, strengthen competencies and shape their own career paths in research, business and society. Our ongoing efforts to foster equal opportunity and diversity concentrate especially on the decided support and the monitoring of the recruitment of women professors as well as other female faculty and staff. Well-established equal opportunity measures are Target Agreements with faculties, incentive and award programs, and a guideline on gender appropriate appointment procedures. At RUB, we wish to promote women in areas in which they are underrepresented, and would like to encourage female candidates to send us their applications. Applications by suitable candidates with severe disabilities and other applicants with equal legal status are likewise most welcome. Our selection procedure follows the European Commission's European Code of Conduct for recruitment of researchers.

Unsolicited marketing is not appreciated.

APPLICATION DEADLINE

You may apply until 31st of December :59pm / before 1st of January 2026 Central European Time (CET) for this position by means of the online application form (click on 'Apply' below on the advertisement on the HaloVerse website).
