Principal Scientist at TNO and Professor at the University of Amsterdam on Oral Systems Biology
Bart Keijser

In my research within the chair of Oral Systems Biology, I strive to unravel the intricate interactions between microbial communities and host physiology in the oral cavity and respiratory tract. By bridging the gap between fundamental science and applications, I hope to develop innovative strategies for preventing and treating oral diseases.

Research area

TNO Healthy Living aims to contribute to human health and wellbeing through development of novel strategies for prevention of (chronic) diseases, and providing individuals the means to make better and more healthy choices in nutrition and lifestyle.

The human microbiome plays a key role in physiology, including immune, metabolic and neuronal processes. Alterations of the microbiome (or dysbiosis) greatly affects our health and long-term disease risk, relating to important elements within TNO’s strategic innovation themes, e.g. Early Life, Prevention, Personalised Health, and Body-Brain.

In my research within the chair of Oral Systems Biology, I aim at unravelling role of the microbiome mouth and respiratory tract in health and disease. Chronic inflammatory diseases of the mouth and respiratory tract impact health of many in society. By using systems biological approaches, I aim to gain insight in pathological processes at the early onset of chronic inflammatory diseases.

Moreover, in my research I also aim to identify beneficial symbiotic functions of our microbiome in infection resistance, immune health, gustatory and olfactory perception. This provides fundaments for novel, microbiome-based strategies for the prevention of disease and optimization of health throughout the span of life. Stimulation of healthy biological processes, and thereby prevention of disease is a paradigm shift in the field of oral and respiratory health care, where the current focus is on treatment of disease.
