Bio4Energy Researchers’ Meeting, 19–20 November 2025

Bio4Energy researchers meet twice a year to share progress, exchange ideas and explore new opportunities for collaboration. This autumn’s meeting will include a special focus on early-career researchers, with dedicated time for PhD students and postdoctoral researchers to present their work and connect with colleagues across the programme.

The meeting will take place on 20 November 2025 at Carl Kempe-salen (KB.E3.03), KBC Building, Umeå University, from 08:30 to 16:00. An optional joint dinner will be held on the evening before, 19 November, at a local restaurant (venue to be announced).

The full programme and registration form will be published here soon.

We look forward to seeing you!
