He is particularly interested in the identification of environmental exposures (exposome) and disease processes associated with different metabolic phenotypes and the underlying mechanisms linking these processes with the development of specific disorders or their co-morbidities. Prof. Orešič has also initiated the popular MZmine open source project, leading to popular software for metabolomics data processing. He currently coordinates European collaborative project ’Inflammation in human early life: targeting impacts on life-course health’ – INITIALISE (https://initialise-project.eu/).
