Postdoctoral position on the chemical ecology of insect-fungal symbiosis The Berasategui Lab at Vrije Universiteit Amsterdam invites applications for a full-time ERC-funded Postdoctoral Researcher to investigate the chemical and functional genomics of defensive fungal symbionts associated with beetles. This project will focus on identifying and characterizing the bioactive compounds produced by a diverse set of fungal mutualists, using a metabologenomics approach to link chemical profiles with biosynthetic gene clusters. The successful candidate will also conduct targeted bioassays to determine which compounds contribute to beetle defense, providing functional insights into the ecological roles of these symbioses. The position is expected to begin in early 2026. It is initially offered as a one-year appointment, with the possibility of extension for up to a total of three years based on performance. Candidate Requirements: - A PhD in Chemistry, Biology, Ecology & Evolution, Genomics, or a closely related field - Demonstrated experience with analytical chemistry - Strong bioinformatics skills (highly desirable) - Excellent communication and interpersonal skills - Willingness to collaborate in a multidisciplinary team environment Applicants should submit the following materials in a single PDF file: 1. A cover letter describing previous research experience, interests, and motivation for applying 2. A current CV 3. Contact information for three academic referees Full consideration will be given to applications received by June 6th, but the position will remain open until filled. Informal inquiries can be directed to Dr. Aileen Berasategui (a.berasateguilopez@vu.nl).

The Berasategui Lab at Vrije Universiteit Amsterdam invites applications for a full-time ERC-funded Postdoctoral Researcher to investigate how mutualistic interactions between phytopathogens and insect vectors influence pathogen virulence. This project will focus on tortoise leaf beetles, their fusarial defensive symbionts, and a shared plant host system to explore whether these mutualisms constrain or promote pathogen virulence. The position is expected to begin in early 2026. It is initially offered as a one-year appointment, with the possibility of extension for up to a total of three years based on performance.
