Based at the University of Angers, the LPG-BIAF is the Angers hub of the UMR 6112. After a period of 12 years operating as a welcome team, the former BIAF laboratory entered into a partnership with the LPG laboratory in Nantes in 2012, creating one single university team in the field of geoscience for the Pays de la Loire region.

Research carried out by the laboratory of Angers fits into the UMR-CNRS 6112 theme of Marine Systems in Transition. We study marine and coastal ecosystems, both in their current state and how they were in the past, in order to tackle four themes:

  1. how current ecosystems operate
  2. the quality of current ecosystems
  3. the development of palaeoceanographic proxies
  4. how these proxies are applied in sedimentary records of the Quaternary Period


Our primary research tools are as follows:

  1. fossilised micro-organisms (benthic and planktonic foraminifera)
  2. geochemistry (diagenetic reactions, the composition for tests on foraminifera)
  3. sedimentology (sediment dynamics and flows)


Our research strategy is based on a combination of observations in the field, laboratory experiments and analysis of sediment core samples.

As of early 2018, the LPG-BIAF was made up of around 25 members: 10 professor-researchers, 2 associate researchers, 5 technical staff members, 2 administrative staff members, 2 post-doctorate/ATER students and 6 PhD students. Each year, we host between 10 and 15 Master’s students on 1 or 2-year courses for lengthy internships.

As far as education is concerned, the LPG-BIAF contributes to the teaching provided as part of the Master’s in Ecology-Environment at the University of Angers and the Master’s in Prehistory, Palaeontology and Paleoenvironment at the University of Rennes I. We are also the host laboratory for the SML Doctoral School (Ocean and Coastal Sciences).

The LPG-BIAF is known worldwide for the studies carried out by the laboratory on foraminifera, studies which systematically apply a multidisciplinary approach, and which are very much at the forefront of current research, and we participate in a wide range of research programmes at an international, national and regional level. Naturally, our research has been the subject of numerous international collaborations, with roughly 60% of our publications co-authored by foreign academics. At this moment in time, our most active international collaborations involve:

  • The University of Aarhus in Denmark
  • The University of Ancona in Italy
  • The Federal Polytechnic School in Lausanne (EPFL) in Switzerland
  • The University of Hamburg, Germany
  • The Natural History Museum in London, the United Kingdom
  • The Royal Netherlands Institute of Sea Research in Texel/Yerseke in the Netherlands
  • The NOC in Southampton, the United Kingdom
  • The University of Utrecht in the Netherlands
  • The University of Vienna in Austria
