Researcher in Biology
University of Helsinki
Finland

Supervisor: Dr. Piret Avila
Faculty: Faculty of Biological and Environmental Sciences
University: University of Helsinki
Unit: Faculty of Biological and Environmental Sciences
Sub-unit: Organismal and Evolutionary Biology Research Programme
Position ID: 4621

Position Overview

The Faculty of Biological and Environmental Sciences and Academy Research Fellow Dr. Piret Avila are seeking a highly motivated Postdoctoral Researcher to develop theoretical work on the evolution of sex-specific differences in immunity and life history traits.

Applications are accepted immediately and will be reviewed on a rolling basis until the position is filled.
The ideal starting date is February/March 2026, but a later start is possible.

This is a fully funded three-year position based at the Viikki campus, University of Helsinki.

Research Focus

The position involves developing mathematical models to understand how natural selection shapes sex-specific immune strategies. The goal is to generate quantitative predictions that can be tested against empirical data from diverse ecological contexts.

The research will use methods from theoretical evolutionary biology, including:

• Optimal control theory

• Life history modelling

• Adaptive dynamics

• Population genetics

This position is part of the interdisciplinary consortium Sex Differences in Immunity at the University of Helsinki, led by Dr. Avila. The consortium brings together researchers across evolutionary biology, immunology, genomics, demography, and statistics to bridge evolutionary and mechanistic explanations of sex differences in immunity.

What We Offer

• Starting salary for postdoctoral researchers of approximately €3,625 per month

• A fully funded three-year position at the University of Helsinki (Viikki campus)

• Opportunity to conduct research within a vibrant interdisciplinary consortium

• Collaboration across disciplines, including research visits to leading international groups

• Funding for attending international conferences

• Access to excellent research resources and professional development opportunities

The University of Helsinki provides comprehensive employee benefits, including occupational health care and health insurance, unemployment and pension funds, a generous holiday package, sports facilities, and opportunities for professional development.
