Andres Wiemken studied Agronomy at the Swiss Federal Institute of Technology (ETH Zürich) and joined the laboratory of Prof. Philippe Matile, in whose laboratory he received his PhD degree, demonstrating for the first time the lysosomal function of the yeast vacuole. He subsequently spent two years as a post-doc at the University of East Anglia in Norwich to study the vacuole in the yeast cell cycle.

He spent half a year at the Rubber Research Institute of Malaysia (Kuala Lumpur) to study the lutods in the latex of rubber trees, and after his return to ETH Zürich, he became interested in the storage of fructans in the vacuoles of Jerusalem artichoke and barley, and also in the possible function of the vacuolar compartment in the mycorrhizal symbiosis.

In 1984, he became a Professor of Botany at the Botanical Institute of the University of Basel. Teaming up with Thomas Boller, one of his former PhD students at ETH Zürich who was at that time already a lecturer in Basel, he established plant-microbe interactions as a central theme in the laboratory, with a focus on the symbiosis of plants with mycorrhizal fungi and rhizobia.

A key research topic in the laboratory, jointly headed by Thomas Boller and Andres Wiemken, remained the role of chitinase and beta-1,3-glucanase in symbiosis ("Molecular biology of Symbiosis"). The laboratory also became interested in the ecological impact of symbioses and plant-pathogen interactions, and it took part in a large interdisciplinary project on biodiversity, sponsored by the Swiss National Research Foundation in the context of the Swiss Priority Programme Environment (SPPE).

Highlights of the joint projects of Andres Wiemken and Thomas Boller were the discovery of microsatellites in fungi, and the finding that the below-ground diversity of mycorrhizal fungi plays a key role in the above-ground biodiversity in plant communities. A second major theme in the laboratory, again jointly headed by Andres Wiemken and Thomas Boller, deals with carbohydrate metabolism and sugar sensing in plants. The biochemistry and molecular biology of fructan metabolism has been a long-standing research interest in the laboratory ("Fructans"), and more recently, based on the previous research of Andres Wiemken on the function and metabolism of trehalose in yeast, he has also become interested in the role of trehalose in plants ("Plants and Trehalose").
