Postdoctoral Position in Biology

University of Helsinki

Department: Faculty of Biological and Environmental Sciences – University of Helsinki, Finland
Deadline: 15 February 2026 (or until suitable candidates are found)
Start Date: Negotiable
Job Type: Full-time
Job Field: Science and Research

About the Position

The Mähönen Lab, led by Academy Professor Ari Pekka Mähönen, is seeking Postdoctoral Researchers and PhD Candidates in Plant Developmental Biology.

The lab focuses on vascular cambium—the tissue responsible for producing secondary xylem (wood) and phloem. Research aims to uncover the molecular mechanisms and intercellular dynamics of bidirectional cell production by vascular cambium stem cells using:

• Lineage tracing techniques
• Molecular genetics
• Proteomics
• Advanced microscopy
• Genomics

Model species include Arabidopsis thaliana, as well as hybrid aspen and silver birch.

Funded projects include Research Council of Finland–funded Academy Professor projects on stem cell fate and a Novo Nordisk Foundation–funded project on wood tissue patterning. Postdoctoral researchers are encouraged to develop independent research lines.

Candidate Profile

Required Qualifications:

• Doctoral researchers: strong background in developmental genetics, plant molecular biology, biochemistry/proteomics, or cell biology
• Postdoctoral researchers: similar expertise, with ability to independently develop research projects
• Excellent communication skills in English (spoken and written)

Desirable Skills:

• Experience in plant developmental biology and cambium research
• Experience with Arabidopsis or tree models

Main Responsibilities

• Conduct research on stem cell fate decisions and wood tissue patterning
• Participate in lab activities and collaborative projects
• Develop independent research projects (postdocs)
• Contribute to publications, presentations, and scientific dissemination

What We Offer

• Contract Duration: Doctoral researchers: up to 4 years; Postdoctoral researchers: 3–5 years (6-month trial period)
• Collaborative, innovative, and inclusive work environment
• Performance-based salary (according to Finnish university collective agreements)
• 5–7 weeks annual leave, flexible working hours
• Occupational health care, access to high-quality sports facilities, and language classes
• Integration into world-leading scientific community in plant sciences
• Access to Viikki campus, a major European bioscience hub
