Thomas Laux is professor for Molecular Genetics and Biotechnology of Plants at the Faculty of Biology of the University of Freiburg. He is the coordinator of Trinational School of Biotechnology Strasbourg which is a joint effort of the Universities Basel, (Switzerland), Strasbourg (France), Karlsruhe (Germany), and Freiburg.
Thomas Laux studied biology in Erlangen and did his PhD thesis on the regulation of fatty acid synthase in rats  at the department of Biochemistry (Prof. Schweizer). After postdoctoral trainings at the University of California Los Angeles with Professor Bob Goldberg and the LMU Munich with Professor Gerd Jürgens, Thomas Laux worked as group leader at the University of Tübingen where he habilitated in 1999. During this stage Thomas Laux initiated his work on stem cell regulation in plant meristems and on early embryo patterning. In 2000, Thomas Laux became professor at the University of Freiburg.
His awards include the August Chevalier Medal of the French Academy of Science and the Cornelia Harte Award of the German Society of Developmental Biology.


FRIAS Project

Stem cells are crucial to replenish the daily loss of cells in animals and the continuous formation of new organs in plants. In addition, their use in medicine and plant Biotechnology has greatly enhanced the opportunities of regenerative biology. Maintenance of stem cells requires the balance of self renewal and cell differentiation by a complex network or regulators and interconnected circuitries. Unveiling the logic of stem cell systems will combine efforts in animal and plant research and applied and theoretical approaches.
