Walter Wahli

In 1980, Wahli became a full professor and the director of the Institute of Animal Biology at the University of Lausanne where he completed several mandates, such as vice-rector for research, postgraduate and continuing education and founding director of the Center for Integrative Genomics. He then served as a professor of metabolic disease at the Lee Kong Chian School of Medicine, a joint medical school of Nanyang Technological University Singapore and Imperial College London, in Singapore. Since 2019, he is a visiting professor at this school.

Wahli has a longstanding interest in nuclear receptors found within cell nuclei which are responsible for sensing steroid hormones, fatty acids and other lipophilic molecules. Upon activation by these ligands, the receptors regulate the expression of specific genes, thereby controlling key biological processes, such embryonic development, homeostasis, and metabolism of the vertebrates. Since 1977, Wahli reported several discoveries related to the molecular mechanism of action of the estrogen receptor and then of the fatty acid-activated peroxisome proliferator- activated receptors (PPARs), for which he was the co-discoverer, in their functions of regulating lipid and glucose metabolism, inflammation, wound-healing, and cell differentiation processes. He also investigated the role of PPARs in the most common liver disease known as non-alcoholic fatty liver disease (NAFLD). He underscored the potential of PPARs as drug targets for NAFLD that is often associated to metabolic syndrome and Type 2 diabetes. Wahli obtained patents for his inventions. His patents include; "Composition for regulating lipid metabolism", (2013) and "Composition for enhancing immunity", (2019).

Walter Wahli (born 23 May 1946 in Moutier) is a Swiss biologist and Professor emeritus at the University of Lausanne and Visiting Professor at Nanyang Technological University of Singapore. His researches have significantly contributed to the understanding of the control of metabolism by regulation of gene expression. He has notably worked on the nuclear receptors, Peroxisome proliferator-activated Receptors, known as PPARs, involved in the energy balance of the body.
