ORGANISATION
The University of Bern (UniBe) is the third largest university in Switzerland and was ranked 104 in the 2025 Times World Universities Rankings. With almost 20,000 students, UniBe offers a vibrant environment set within the city centre of Bern, minutes from the train station and very well served by public transport. The position will be hosted within the Department of Chemistry, Biochemistry, and Pharmaceutical Sciences (DCBP) (https://www.dcbp.unibe.ch/index_eng.html), a highly interdisciplinary department that brings together diverse research groups and houses state-of-the-art facilities, including X-ray, NMR, and advanced mass spectrometry instrumentation. The DCBP places a strong emphasis on sustainability, with catalysis in its various forms serving as a central research theme across many laboratories. In 2025, the department took a significant step toward integrating biocatalysis within the organic chemistry domain, dedicating an entire floor of the building to the laboratories of Professors Paradisi and Buller. The research group led by Rebecca Buller focuses on advancing biocatalysis and enzyme engineering to support sustainable chemical synthesis. The team conducts studies to tailor enzymes through bioinformatics, directed evolution, and non-canonical amino acid incorporation, for enhanced activity, selectivity, and stability, and to enable both new-to-nature reactions and more efficient production of pharmaceuticals and other fine chemicals. In addition, the group works on broadening the enzymatic toolbox by sourcing and identifying novel biocatalysts through bioinformatics approaches.
ROLES AND RESPONSIBILITIES
The main part of your PhD research (4 years in total) will be carried out at the University of Bern (UniBe, Switzerland) under the supervision of Prof. Francesca Paradisi in the Department of Chemistry, Biochemistry, and Pharmaceutical Sciences. Within these four years, an academic research stay (of 12 months) will take place at the University of Groningen (RUG, the Netherlands) under the supervision of Prof. Sandy Schmidt. Additionally, an industrial secondment at the company inSEIT (Switzerland) is foreseen. The Horizon Europe Marie Skłodowska-Curie Actions (MSCA) – Doctoral Network (DN) project starts in January 2026. The start of the PhD project is planned for as early as 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 (UniBe, Switzerland and RUG, the Netherlands). 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. Additional duties at the University of Bern will include mandatory undergraduate lab supervision.
The PhD research will focus on:
- Interdisciplinary project on bioinformatics, biocatalysis, and chemistry,
- screening of lysine cyclodeamidases (LCDs) and identification and selection of non-heme iron-dependent halogenases (academic secondment RUG) with activity towards an array of lysine-like substrates,
- enzyme expression and characterization,
- evaluation of candidate enzymes for selectivity, TOF and overall performance in chemoenzymatic cascade,
- enzyme immobilization (industrial secondment),
- enzyme engineering,
- implementation of chemo-enzymatic reaction cascades in continuous flow.
Primary supervisor: Prof. Dr. Francesca Paradisi
