Quote:

“As part of the R&D team, we investigate beneficial good bacteria, called probiotics. We aim to understand how probiotics work in our bodies and provide health benefits, for instance, by supporting the function of the microbes within us. In my role I am especially intrigued by how probiotics could support women’s health, like how probiotics support mothers’ health in pregnancy.”

What interested you in working in the field of probiotics?

“I have been always very interested in biology, bacteria and viruses. During my master’s studies in the University of Helsinki I specialized in infectious diseases. In my PhD studies, I directed my interest into human microbiota and probiotics and became highly curious how supporting the endogenous bacteria in our bodies could be an alternative solution to counteract against infectious diseases and to support our health.”
