Fribourg profile

The Department of Biology offers a PhD curriculum in Biology. This programme is fully given in English and comprises a personal research project to be taken over 3-4 years. It also includes seminars and lectures according to the bylaws of the Fribourg Graduate School of Life Sciences and Medicine (FGLM).

The biology laboratories at the University of Fribourg investigate three main areas of research:

Ecology and Evolution
This research area investigates organismic biology with a special focus on ecology and evolution. Current research interests include food web structure, conservation biology, invasive species, agro-ecology, eco-evolutionary feedbacks, life-history evolution, inbreeding depression, evolution in fragmented habitats, genome evolution, and population genetics. The organisms investigated are whole food webs, fruit flies (Drosophila melanogaster), as well as plants such as relatives of Arabidopsis (Arabis, Biscuttella) and grasses (Aegilops).

Neuro- and Developmental Biology
The laboratories investigate the mechanisms that govern animal development and the structure and function of the nervous system in the following model systems: The fruit fly Drosophila melanogaster, the nematode Caenorhabditis elegans, the zebra fish Danio rerio and the mouse. Research topics include molecular aspects of regeneration, cell differentiation in somatic and germ line tissues, neuronal outgrowth and connectivity, the function of neuronal circuits, behaviour, chemoreceptors, and aging. The tools employed are molecular genetics, molecular biology, protein analysis, microscopy and imaging, behavioural analysis and many more.

Plant and microbial sciences
This area emphasises the cellular and molecular aspects of pathogenic and symbiotic plant-microbe interactions. The research groups focus on aspects ranging from plant-microbe communication, initiation of defences, metabolic and hormonal adjustments, and the effects of various microbes on plant nutrition, growth and health. Current tools comprise molecular biology, reverse genetics, imaging, analytics, and biochemistry. The training both in practical and theoretical areas will prepare the PhD students for the challenge of the professional world.

PhD students learn how to conduct a research project in an independent manner. They will also learn how to interpret scientific data and to present them. Furthermore, students are expected to be able to think independently about their research topic, to trouble-check their experiments, evaluate their data and put them into a general context, and of course to work in a team. PhD students participate at national and international scientific meetings in order to broaden their knowledge and to establish a scientific and social network.

PhD students in the Department of Biology are remunerated according to standards of the Faculty of Science and Medicine.

To register to the doctoral programme, candidates select a laboratory in which they plan to carry out their PhD (see Contact). They read the relevant publications and then contact the group leader to ask for a possible opening.

Alternatively, candidates look for openings that are posted by the FGLM. The selection procedure is carried out twice a year. It comprises a 15-minute oral presentation and discussions with the various group leaders.

Doctoral school



In order to be admitted to a doctorate the candidate must have been awarded an academic bachelor's and master's degree or an equivalent qualification from a university recognised by the University of Fribourg.

Before applying for a doctorate the candidate must contact a professor who would be willing to supervise the thesis work.

There is no general right to be admitted to a doctorate.

The respective conditions of admission for each doctoral study programme are reserved.
