The Organismal and Evolutionary Biology Research Programme (OEB) invites applications for a

POSTDOCTORAL RESEARCHER

in statistical ecology for a fixed term of two years. There will be a trial period of six months in the beginning.

The post doc position is part of the Research Centre for Ecological Change and is funded by the Jane and Aatos Erkko Foundation. PIs of the Centre are prof. Anna-Liisa Laine, prof. Otso Ovaskainen, prof. Tomas Roslin, assist. prof. Jarno Vanhatalo and Dr Marjo Saastamoinen. The starting date is 1 May 2019, but a later starting date can be negotiated.

The overarching aim of the Centre is to generate a coordinated analysis of long-term ecological data to understand impacts of global change. To unravel how populations and interactions between species in nature are responding to ongoing environmental change, the project takes advantage of the unique long-term datasets collected in Finland. The centre also develops state-of-the-art methodology for analysing long-term spatially structured data sets within a joint species distribution modeling framework. For more information please visit our website Research Centre for Ecological Change (https://www.helsinki.fi/en/researchgroups/research-centre-for-ecological…).

The post doc takes part in the development of statistical methods for analyzing long-term ecological data and in statistical analyzes within the Research Centre for Ecological Change. For recent methodological publications, see the reference list at the end.

The methodological work focuses on development of Hierarchical Modelling of Species Communities (HMSC) and hierarchical multivariate Gaussian processes. HMSC is a joint species distribution modelling framework that can be used for the statistical analysis of data on species occurrence,
environmental covariates, functional traits and phylogenetic relationships. HMSC can be applied to hierarchical, spatial and temporal study designs, and it applies to many kinds of response data (presence/absence, counts, etc.). Gaussian processes are a flexible and versatile modeling approach, and are rapidly spreading through statistical ecology as tools for species distribution and population dynamics modeling. Gaussian processes are used to model spatial and spatiotemporal heterogeneity in data and describe species responses to their environment in a nonparametric manner.

The successful applicant should have doctoral degree in ecology, statistic or other relevant field and will have experience in the development and application of Bayesian methods for computationally challenging problems. A successful candidate will also have experience in scientific computing. Prior experience in ecology is not necessary, but is counted as an advantage. The exact direction to which the post doc will develop HMSC and Gaussian process models can be agreed upon based on the experience and interests of the candidate.

For more information, contact prof. Otso Ovaskainen (otso.ovaskainen(at)helsinki.fi) and/or assistant prof. Jarno Vanhatalo (jarno.vanhatalo(at)helsinki.fi).

The salary of the successful candidate will be based on level 5 – 6 of the demands level chart for teaching and research personnel in the salary system of Finnish universities. In addition, the appointee will be paid a salary component based on personal performance. The starting salary will be ca. 3300 – 3800 euros/month, depending on the appointee’s qualifications and experience.

Applications should include the following documents as a single pdf file: motivational letter (max 1 page), CV (max 2 pages), and publication list. Please also include contact information of two persons willing to provide a reference letter by separate request.

Please submit your application using the University of Helsinki Recruitment System via the Apply for the position link. Applicants who are employees of the University of Helsinki are requested to leave their application via the SAP HR portal. The deadline for submitting the application is 1 April 2019.

In the international university rankings, the University of Helsinki typically ranks among the top 100. The University of Helsinki seeks solutions for global challenges and creates new ways of thinking for the best of the humanity. Through the power of science, the University has contributed to society, education and welfare since 1640.

The Future Sustainable Food Systems research group, led by Associate Professor Hanna Tuomisto, is affiliated with the Faculty of Agriculture and Forestry and the Helsinki Institute of Sustainability Science (HELSUS). The recently established growing group is interested in researching potential of novel technologies such as cellular agriculture that utilises cell-culturing technologies for food production. The Future Sustainable Food Systems research group is seeking for

POSTDOCTORAL RESEARCHER/DOCTORAL STUDENT in Sustainable Food Systems

for a temporary 2-3 year contract (depending on the level of the position and starting date) to work in a project called ”Assessing the potential of novel food production technologies to improve the environmental sustainability of food systems”. The project explores the potential of novel technologies, such as vertical farming and cellular agriculture (i.e. use of cell-culturing technologies for food production), to contribute to the improvement of the sustainability of global food systems. The project will develop new sustainability assessment methods and approaches that consider the wider consequential impacts such as the changes in land use, energy generation and composition of diets that are generally ignored by the commonly used environmental assessment methods.

The postdoctoral researcher/doctoral student will contribute to the development of novel frameworks, approaches and methods for consequential sustainability assessment of food systems and use these methods for assessing the impacts of introducing novel food production technologies in different geographic areas. The appointed researcher will work in collaboration with the other members of the Future Sustainable Food Systems research group and will be supervised by the team leader Assoc. prof. Hanna Tuomisto.

The candidate is expected to have:

• a degree (a master degree for the doctoral student position, and a doctoral degree for the postdoctoral researcher position) in environmental sciences, engineering, agricultural sciences, environmental economics, or other relevant field
• ability to work independently and as a part of a team
• strong quantitative skills and understanding of environmental impacts
• knowledge of sustainability assessment methods (e.g. life cycle assessment) is seen as a benefit.

A person appointed as a doctoral student is required to apply for the right for doctoral studies from the University of Helsinki within six months after starting the post.

The salary of a postdoctoral researcher will be based on levels 5 and doctoral student on levels 2 – 4 of the job requirement scheme for teaching and research staff in the salary system of Finnish universities. For a postdoc the starting salary will be 3 200 euros/month and for the doctoral student the starting salary will be 2200 – 2400 euros/month, depending on the appointee’s qualifications and experience. The University of Helsinki offers comprehensive services to its employees, including occupational health care and health insurance, sports facilities, and opportunities for professional development. The International Staff Services office (https://www.helsinki.fi/en/university/working-at-the-university) assists employees from abroad with their transition to work and life in Finland. A six-month trial period will be applied.

The attachment required for the application include (preferable in a single pdf-file):

1) A cover letter explaining the applicant’s motivation for the research work and a short research plan (e.g. approach, research materials and methods) (up to 3 pages)
2) Curriculum vitae showing the applicant’s education, completed qualifications, work experience, possible list of publications and contact information of 2 persons for references (up to 3 pages)
3) Copies of Master’s and Bachelor’s degree certificates and official transcripts of the records, and their translations, if the originals are not in Finnish, Swedish or English
4) A proof of proficiency in Finnish, Swedish or English, if the applicant is not a native speaker or educated in any of them.
