You will be part of the 2018 VICI grant program 'How gut bacteria and stress shape child development'. You will join our very dynamic and highly collaborative research group (DPBlab), a multidisciplinary group of senior and junior researchers. You will help design, preregister, and carry out the RCT study. You will contact the childcare centers and parents, train the volunteers, and collect behavioral, psychological, health, and biological data. Data collection will be in childcare centers and possibly also in the lab or home environments. You will analyse the data and report the results in scientific journals and conferences, and in a doctoral dissertation.

We are looking for a highly capable, eager, and intrinsically motivated PhD candidate. The project is embedded in our developmental psychobiology research group (DPBLab; PI: Prof.dr. Carolina de Weerth) at the Donders Institute for Brain, Cognition and Behaviour in Nijmegen (the Netherlands). This position is part of a program started with a personal VICI grant awarded to de Weerth by the Netherlands Organisation for Scientific Research (NWO). The grant is on children's gut microbial colonization in relation to stress early in life and later brain functioning, behavior, and cognition. The colonization of the gut by microbes is of interest because it is assumed to play an essential role in children's physical, behavioral, and cognitive development.

The aim of this PhD project is to examine whether a naturalistic stress-reducing intervention program based on caregiver-infant contact can positively affect infant gut microbial colonization and infant behavioral and cognitive development. In a RCT, caregiver-infant contact in 3-month-old infants starting center-based childcare will be increased in the intervention group during the hours spent in childcare. Trained volunteers will provide this extra caregiver-infant contact.

The idea behind this study is that by means of extra physical contact and high quality one-to-one interaction, young infants' stress levels upon entry to childcare will be reduced. Heightened stress hormones in the period of adaption to childcare were found in an earlier study of our group (Albers et al., 2016) and may be due to reduced ono-to-one attention, maternal separation, changing caregivers, etc. This study will hence start to uncover causal relations between the infant's stress while adapting to childcare and the quality of the early microbial colonization and the infant's development. Additionally, it will potentially provide a simple, yet efficient, stress-reducing intervention that may also have positive effects on infant physical and psychological health. An additional focus of interest in this study is on how the intervention affects mood and well-being of the infants' parents, the professional childcare caregivers, and the volunteers providing the contact.
