I currently hold an Academy of Finland Research Fellowship, which is comparable to a tenure track position, at the Faculty of Sport and Health Sciences, University of Jyväskylä, Finland. I am also a Docent (Adjunct Professor) in Bacteriology at the Faculty of Medicine, University of Turku, Finland. My research team focuses on studying host-gut microtia interactions related to health and disease. Our approach has been in detecting microbiota-related phenomena in human cohorts and then proving the biological significance and the underlying mechanisms of the phenomena using cellular and animal models. In this way, we have found ways to treat metabolic diseases, such as non-alcoholic fatty liver disease, by using or targeting specific microbes.
