Research interests:

The microbial communities that colonize different regions of the human gut influence many aspects of health. Recent research has provided strong evidence for the role of the commensal gut microbiota in brain function and behavior. Bidirectional communication between gut microbiota and components of the gut–brain axis influence normal homeostasis and may contribute to risk of disease.

Diet is considered among the most crucial factors, which have an impact on microbial community composition from infancy to old age. Thus, dietary interventions may have the potential to modulate stress-response and overall behavior associated with gut–brain axis dysfunction and should open up new possibilities for health manipulation.

Among our main interests are:

  1. Investigating the effects of personalized, diet-induced alterations in microbiota on sleep quality in older adults.
  2. Exploring the associations between gut microbiota and geriatric depression, and the potential of a nutrition induced microbiota alterations diet, aimed to improve quality of life and wellbeing in older adults.
  3. Studying the effect and\or involvement of microbial metabolites on sleep, depression and ADHD.
  4. In addition, we are involved in two more studies dealing with microbiome. One, which deals with probiotic treatment for students with attention deficiency disorder, and the second, is concerned with the effect of probiotic supplementation on the ability to perform intense endurance exercises among master's runners and competitive cyclists.
