Markus Lehtinen, PhD

Principal Scientist

“I work in a team that investigates what kind of effects bacteria, tiny living creatures in our gut, have on human health. My role is to help the team to understand the effect of bacteria on the immune system, composed of tiny human cells, that fights off the bad bacteria and takes care of the good bacteria.”

What do you like best about your job?

“I have for long wanted to understand how human biology in general and immune system specifically works. Thus, the opportunity to participate in and contribute to leading edge global scientific projects and to learn from colleagues, collaborators and scientific community different aspects of science and product development has been intriguing.”

What interested you in working in the field of probiotics?

“To understand immunology requires understanding of its counterpart – microbes.”

Why do you think it’s important to take probiotics?

“Human studies in the past decade have shown associations between dysbiotic microbiota and health risks. Thus, having healthy microbiota could help in maintaining health. Although much research is still required to prove health benefits of specific probiotics, they are safe to use with no harm and have potential in maintaining the homeostasis of the microbiota that supports human health.”

What work-related accomplishment are you most proud of?

“In 2011 Medical Faculty of the University of Helsinki recognized my work on how innate immunity differentiates between self and non-self with the Thesis of the Year Award.”
