Based on long-term experience in ecosystem-oriented research, math modelling and software development and experiments in the context of chronic health challenges, ETSS AG has focused on scientific (systemic) issues of metabolism, mental and general health and their interactions with food and environment (contamination) as well as with game-theoretical foundations of economic and other aspects of a good life. We also address product engineering relating to, for example, the supply of nutrients, detoxification issues, neuro-, keto- and gluconeogenesis, auto-phagocytosis and other.
