Job description / Project description / Development plan:

The position will be affiliated with the Section for Genetics and Evolutionary Biology (EVO-GENE) with collaborators at the Centre for Ecological and Evolutionary Synthesis (CEES) at the Department of Biosciences, University of Oslo.

The post doc fellow will be working on the project “Effects of polyploidization during adaptive evolution in yeasts (PloidYeast)” lead by Dr. David Peris (PI) and funded by the Research Council of Norway (RCN 324253 ). The candidate will work in close collaboration with the PI, Dr. Sara Orellana, Dr. Inger Skrede, Prof. Håvard Kauserud, Oslo Mycology Group members (Postdoc, PhD and master students) and researchers at the Institute of Agrochemistry and Food Technology (IATA) –CSIC, Spain. In addition, the candidate will be part of an international collaborative research team from Stockholm University, Sweden (Dr. Rike Stelkens); Institute for Integrative Systems Biology (I2SysBio)-CSIC, Spain (Dr. Ana Conesa); Ghent University, Belgium (Dr. Yves Van de Peer); and Lawrence-Berkeley National Laboratory, USA (Dr. Héctor García). This research team provides an excellent scientific framework, with specialists in mycology, speciation, hybridization, food biotechnology, evolutionary biology, population genomics, multiomics integration and machine learning model applications.

Climatic change and human actions are threatening the sustainability of food security. United Nations has launched four aims within the sustainable development plan to maintain and ensure food security. In PloidYeast, we aim to apply a new collection of yeasts to offer new biotechnological approaches that can solve UN challenges, that is convert the food chain in a sustainable and a circular process. To accomplish this objective, we will make use of a recurrent evolutionary phenomenon observed in several industrial yeasts. This phenomenon is called polyploidization where the increase of the number of copies of the genome facilitates the adaptation to industrial conditions and might generate yeasts with desired industrial traits, accommodated to reach the sustainability of the food security. We will apply a multidisciplinary approach combining microbiology, molecular and genetic engineering methods, bioinformatics and mathematical modelling to generate the new yeasts and learn how polyploidization improves adaptation to industrial conditions. We know that increasing the number of copies in a yeast, by introducing the genome of multiple yeasts with different but desired industrial traits, generates a new yeast with the combination of the parental traits.

The post doc fellow will generate multiple omic layers (genomic, transcriptomic, proteomic, growth curves) of ancestral and evolved yeast polyploids in different media conditions. She/he will develop bioinformatic tools to integrate them by making use of machine learning techniques to infer the genomic regions associated with the phenomic regions related with the adaptation.

The post doctoral fellow is expected to perform at least one Research Stay Abroad ( ) in any of the international collaborator lab mentioned above to expand the skills and knowledge related with the PloidYeast project aims and the postdoctoral career necessities.

The main purpose of a postdoctoral fellowship is to provide the candidates with enhanced skills to pursue a scientific top position within or beyond academia. To promote a strategic career path, all postdoctoral research fellows are required to submit a professional development plan no later than one month after commencement of the postdoctoral period.

It is expected that the successful candidate will be able to complete the project in the course of the period of employment.

Qualification requirements:

The Faculty of Mathematics and Natural Sciences has a strategic ambition to be among Europe’s leading communities for research, education and innovation. Candidates for these fellowships will be selected in accordance with this, and expected to be in the upper segment of their class with respect to academic credentials.

  • Applicants must hold a degree equivalent to a Norwegian doctoral degree in in a field relevant for the project, including Genomics, Bioinformatics, Evolutionary Biology, Food Microbiology or similar. Doctoral dissertation must be submitted for evaluation by the closing date. Only applicants with an approved doctoral thesis and public defence are eligible for appointment.
  • Knowledge in comparative genomics, population genomics and evolutionary biology
  • Experience in bioinformatics applied to genomic data
  • Fluent oral and written communication skills in English

Personal skills:
  • A strong interest in fungal biology, fungal genomics, and bioinformatics
  • Demonstrated ability in scientific writing and publications in relevant international scientific journals
  • We seek a highly motivated, enthusiastic and hard-working candidate. Applicant must show good interpersonal skills and be willing to work in close collaboration with the project PI and other members of the international project team, as well as have the ability to work independently.

Personal suitability for the position will be emphasized.
