Postdoctoral Researcher in hydrological and ecosystem modelling

We are now looking for

a Postdoctoral researcher in hydrological and ecosystem modelling

The postdoctoral position is linked to large-scale and long-term research in the water sector at the Flagship DIWA - Digital Waters, and SAFIRE - Safeguarding Biodiversity through Interdisciplinary Research on Habitat Restoration- a Profi8 programme at the University of Oulu, funded by the Research Council Finland. The position is located at the Water, Energy and Environmental Engineering research unit, in the Faculty of Technology. Our water research team includes 4 research groups with a strong focus on various aspects of water engineering, including hydrological modelling, cold climate hydrology, hydrological process studies, groundwater research, water quality, water management, water supply, treatment, and protection. In hydrology, the research includes studies at our research stations and supersites in Finland with a unique and developing infrastructure. We are active in interdisciplinary studies in Finland and different regions abroad, with studies on climate, land, energy, and water analysis, modelling, and management.

Your responsibilities

We are looking for a talented and experienced postdoctoral researcher with a strong background in process-based hydrological, ecosystem, or earth system modelling. You will contribute to ongoing research projects focused on understanding and modelling hydrological and biogeochemical processes and their interactions with ecosystems under changing environmental conditions. The work will involve developing and applying models to simulate water and nutrient fluxes, and feedback between terrestrial ecosystems and climate systems, with a focus on Arctic and boreal environments. Your responsibilities will include:

• Applying models to simulate water and nutrient fluxes, and feedback between terrestrial ecosystems and climate systems, focusing on Arctic and boreal environments.
• Combine numerical models, analyse large datasets, and collaborate with interdisciplinary teams.
• Collaborating with SAFIRE profiling researchers, aiming to drive a paradigm shift in habitat restoration through transdisciplinary research and societal engagement.
• Participating in doctoral supervision and education.
• Collaborating with other postdoctoral researchers and senior staff.

Through the DIWA flagship, you will collaborate with several national research partners, doctoral researchers, and postdoctoral researchers in a strong team with a focus on digitalisation in hydrology, water research, and management, using and developing different types of solutions for monitoring, data handling, data fusion, and modelling approaches to develop digital twins.

What we offer

We offer you an interesting and versatile position as part of a large and growing digital water research cluster in Finland and the SAFIRE profiling research team. We help you to grow and realise your full scientific potential and contribution. You will have the opportunity to develop professionally with the help of an experienced and enthusiastic team. You will also have access to our unique global infrastructure, where new studies can be initiated in collaboration with our team members.
