His academic career started in 1937 with his appointment as an assistant in the Laboratory of Geology at the State University of Ghent.
[2] His geological interest was related to the sedimentology of the Cenozoic formations of the North Sea Basin, the Quaternary in Belgium, the fossil periglacial structures, the evolution of the basin of the Scheldt during the Quaternary and of the coastal plain during the Holocene, the fluctuation of the sea level, etc.
The project, which started in 1947, was funded by the Instituut tot Aanmoediging van het Wetenschappelijk Onderzoek in Nijverheid en Landbouw (IWONL) (Institute for the Promotion of Scientific Research into Industry and Agriculture).
[7] In order to realize the soil map, three different centers collaborated in the recording of data: Leuven, Gembloux and Ghent.
From 1950 onwards, René Tavernier was the director of the Center of Soil Cartography – Centrum voor Bodemkartering (C.V.B.)
[9] René Tavernier took part in the organization of the 4th Congress of the International Soil Science Society in Amsterdam in 1950, where he was elected President of ISSS.
Following the 5th ISSS congress, which took place in 1954 in Léopoldville (Kinshasa), he worked on a classification system for tropical soils, in collaboration with the National Institute of Agricultural Studies in the Belgian Congo (INEAC-NILCO).
[11] In 1958, René Tavernier was a member of the executive committee of the National Institute of Agricultural Studies in the Belgian Congo (INEAC-NILCO).
A list of Tavernier's publications, books and articles, can be found in Liber memorialis Rijksuniversiteit te Gent, 1960, pp. 231–234.
