The main research interests of Aristides Tsatsakis include biomonitoring and risk assessments of xenobiotics as well as links of chronic exposure to them at low doses with health problems and diseases. He developed numerous biomarkers of exposure and effects for various chemicals, in particular pesticides, pharmaceuticals, etc., uncovering the mechanistic understanding of the mode of action and adverse outcome pathways leading to clinical effects and chronic diseases (metabolic, autoimmune, cancer, etc.).
