Dr. Joachim Hans
Director Flavour Ingredients,
Plant Sourcing Manager
Dr. Joachim Hans studied biology at the University of Tübingen and moved on to the Leibniz-Institute of Plant Biochemistry in Halle (Saale) for his PhD, focusing on plant natural products accumulating in symbiotic plant-fungus interactions. After a short stay as a PostDoc at the Scottish Crop Research Institute (SCRI, Dundee, UK) he took on a position as Scientific Employee / Head of Laboratory at the Department of Pharmaceutical Biology, University of Marburg, investigating biosynthetic pathways for natural products in medicinal plants. Dr. Hans has 7 years of experience in plant natural product research with a strong background in plant protein biochemistry and molecular biology. He joined InterMed Discovery in April 2008 as Research Scientist and Plant Sourcing Manager.
