The Faculty of Biological and Environmental Sciences at the University of Helsinki is inviting applications for doctoral and postdoctoral researcher positions in plant developmental biology.
These positions are available in the research group led by Academy Professor Ari Pekka Mähönen, a world-recognized expert in plant stem cell biology and vascular development. The group investigates the fundamental mechanisms that control vascular cambium activity, a key process responsible for wood and phloem formation in plants.
This is an outstanding opportunity for early-career researchers seeking advanced training in a top-tier European research environment.
Research Focus of the Mähönen Lab
The vascular cambium is a stem cell tissue that produces secondary xylem (wood) and phloem, enabling plant growth and long-term carbon storage. The overarching goal of the group is to uncover the molecular and cellular mechanisms governing bidirectional cell production by cambial stem cells.
Current research approaches include:
- Lineage tracing and stem cell fate mapping
- Molecular genetics and functional genomics
- Proteomics and biochemical analyses
- Advanced microscopy and imaging techniques
- Genomic approaches in model and tree species
Research is conducted using Arabidopsis thaliana and extended to hybrid aspen and silver birch, offering a unique bridge between model systems and woody plants.
Available Research Projects
The lab is recruiting PhD students and postdoctoral researchers to work on projects funded by:
- The Research Council of Finland (Academy Professor funding), focusing on stem cell fate decisions in cambium
- The Novo Nordisk Foundation, supporting research on wood tissue patterning in birch and aspen
Specific project topics will be defined together with selected candidates and discussed in detail during the interview process, allowing alignment with individual expertise and interests.
Postdoctoral researchers are encouraged to develop independent research directions within the group’s scientific framework.
Candidate Profile and Qualifications
Applicants with expertise in one or more of the following areas are encouraged to apply:
- Developmental genetics
- Plant molecular biology
- Biochemistry or proteomics
- Tree physiology
- Cell and tissue biology
Strong communication skills and fluency in written and spoken English are required. Prior experience with interdisciplinary research and advanced experimental techniques will be considered an advantage.
