Are you looking for PhD stipend?

PhD studies at University of Bergen are based on employment at UiB or a cooperating research institute such as Norce or the Institue of Marine Research. All PhD positions at UiB must be openly advertised. There is thus no reason to contact a TEG researcher to ask for a PhD opportunity. It is possible, however, to contact a researcher to propose a PhD project within one of TEGs research fields, and to work on a joint grant application that can be submitted to the Research Council of Norway (RCN). The deadline for such applications is normally in March, and RCN requires that the supervisor is the formal applicant. The competition within RCN is strong, with more than 90% rejection rate. Suggestions for such proposals must therefore come months before the deadline.

Looking for a Master’s project?

The Theoretical Ecology Group welcomes new Master’s students in all our research themes. Here are some potential topics:

 
Insitute of Marine Research maintains a list of potential Master's topics.

Some of our colleagues in Bergen and nearby offer projects on related topics. Check their pages for updates:

  • Terje Lislevand at the University Museum of Bergen offers field projects on birds.
  • Monica Solberg at the Institute of Marine Research offers masters theses on interactions between wild and farmed Atlantic salmon.

You can also check our Research web pages and contact potential supervisors directly to inquire whether they will have an opening for new MSc students in the near future. The best way to make first contact is to present your background and research interests briefly in an email.

Information on application dates, recommended or required courses, and many other practicalities for being a Master of Science (MSc) student at Department of Biological Sciences, University of Bergen, can be found here.

Most or all MSc education at the Department of Biological Sciences (and the Faculty of Science) is in English, and most MSc theses are written in English.
