Prof. Francesco Visioli (Section 1) 

Department of Molecular Medicine, University of Padua, Italy


The research interest of Prof. Francesco Visioli concerns essential fatty acids, namely those of the omega 3 series, and (poly)phenols, as related to atherosclerosis and cardiovascular disease. Furthermore, Prof. Visoli’s reaserch group discovered the biological and pharmacological properties of olive oil phenolics, including hydroxytyrosol. Therefore, he researched bioactive components of plant foods, including lycopene from tomato and biophenols from wild greens. Prof. Visioli studied Pharmacy and Pharmaceutical Chemistry at the University of Milan and received a PhD in Biotechnology from the University of Brescia. After receiving his habilitation in the field of physiopathology at the Sorbonne Université in Paris, where he directed the “Micronutrients and cardiovascular disease” unit, he is now Professor of human nutrition at the University of Padua, Italy.

Prof. Visoli is the Editor in Chief of PharmaNutrition and has a publication record of more than 400 papers and book chapters, which have been cited more than 15,000 times. Moreover, he was a member of the Board of Directors of the International Society for the Study of Fatty Acids and Lipids (ISSFAL). Currently, he is the Leader of the “Fats and Human Health” division of Eurofed Lipid and was a member of the EFSA GMO Panel.

Prof. Christoph Wilhelm (Section 2)

Institute of Clinical Chemistry and Clinical Pharmacology, University Clinic Bonn, Germany


Prof. Christoph Wilhelm has longterm experience in the research of a unique group of immune cells termed innate lymphoid cells (ILC). His scientific focus is to understand how these cells protect the barrier sites of our body such as the lung, skin and gut and to understand the maintenance of ILC mediated barrier immunity in the context of malnutrition. The overall aim of his research is to understand the link between westernization and the growing health problem of chronic inflammatory conditions such as inflammatory bowl disease (IBD) and asthma. In 2007, Prof. Wilhelm received his Master Degree at the University of Munich in Germany. Around four years later, in 2011, he gained his PhD at the National Institute for Medical Research in London, UK. Afterwards, he worked as Postdoctoral Fellow at the National Institutes of Health in the USA, where he stayed for four years. In 2015, he returned to Germany and started working at the University Clinic in Bonn as Principal Investigator. Currently, he holds the position as Professor and Group leader of the Clinical Chemistry and Clinical Pharmacology division.

Furthermore, Prof. Wilhelm received several honors and awards like the NIH Fellow Award for Research Excellence (FARE award), the Keystone Symposia travel fellowship for oral presentation at the Keystone Symposia 2014 and the Society of Mucosal Immunology travel fellowship.

Prof. Wataru Inoue (Section 5)

Professor of Physiology and Pharmacology, University of Western Ontario, Canada


Prof. Wataru Inoue’s research program investigates the circuit, cellular and molecular mechanisms of stress-induced neural plasticity that contribute to behavioural physiological abnormalities with relevance to stress-related disorders. His main research focus is on hypothalamic neurons and their local circuits that regulate the neuroendocrine stress response. He uses chronic stress paradigms in mice and rats to identify specific forms of neutral plasticity that may underlie the physiological and behavioural abnormalities relevant to stress-related disorders. Inoue received his Bachelor and Master Degree at the Kyoto University in Japan. In 2009, he obtained his PhD at the Department of Neurology and Neurosurgery at McGill University in Montreal, Canada. From 2009 to 2014, he worked as Postdoctoral Research Fellow at the Hotchkiss Brain Institute in Calgary, Canada. After that, he started working as Assistant Professor at University of Western Ontario and currently holds the position as Associate Professor.

Furthermore, he is a member of the Society for Neuroscience, the Canadian Association for Neuroscience, the Japan Neuroscience Society and the International Society for Neurochemistry. From 2016 to 2019, he received the New Investigator Award from the Ontario Mental Health Foundation.

From 2002 to 2006, he worked at the Faculties of Medicine and Veterinary Medicine at the Justus Liebig University in Giessen, where he received his PhD in 2006. At that time, he was a member of the German Research Foundation (DFG) sponsored Graduate College “Cell-Cell Interaction in Reproduction”. Afterwards, he worked as Postdoctoral Researcher until 2007 in Giessen. For the next two years, Prof. Kowalewski pursued a postdoctoral training at the Department of Cell Biology and Biochemistry at the Texas Tech University Health Science Center, School of Medicine, in the USA. Since 2009, he works at the Institute of Veterinary Anatomy, Vetsuisse Faculty at the University of Zurich, Switzerland, where he received his Habilitation in 2012 and currently holds the position as Professor of Veterinary Anatomy, Histology and Embryology as well as the position as Director of the Institute of Veterinary Anatomy.

 Dr. Holger Kühnhold (Section 7) 

Working Group Experimental Aquaculture, Leibniz Centre for Tropical Marine Research GmbH Bremen, Germany


Dr. Holger Kühnhold studied Maritime Technologies as well as Aquaculture and Marine Resource Management at the Bremerhaven University of Applied Sciences, Germany, and at the Wageningen University & Research, Netherlands. In his Doctoral Thesis, he was investigating biochemical and molecular adaptations to temperature stress in sea cucumbers. The goal of his research project, which he wrote in cooperation with the Leibniz Centre for Tropical Marine Ecology (ZMT) GmbH in Bremen, was to establish functional biomarkers as condition indicators for sea cucumbers in aquaculture settings as well as in the wild. Therefore, he did field work in Portugal and Indonesia, where Kühnhold forwarded sustainable aquaculture practices by promoting sea cucumbers as potential candidates in Integrated Multi-Trophic Aquaculture (IMTA) systems. After receiving his PhD, he worked for more than a year at the University College Cork as Postdoctoral Researcher. In June 2019, Dr. Kühnhold returned to the Leibniz Centre for Tropical Marine Research (ZMT) GmbH, where he is currently working as a Senior Researcher within the project “Food for Future” (F4F,

In the project F4F, the marine biologist conducts research at the interface between ecophysiology and aquaculture. His research focuses on the utilization of marine invertebrates (e.g. sea cucumbers and jellyfish) and aquatic plants (e.g. duckweed) for human nutrition. On the one hand, this involves determining optimal culture conditions for promising target species in various aquaculture systems. On the other hand, it is about manipulating environmental parameters such as temperature, light quality and UV radiation to specifically increase the production of important nutrients. Overall, the question is how we can better utilize the biomass at the bottom of marine food chains for global food security.
