From 12 July – 16 July, members of the DPB lab successfully led the 4th edition of the Radboud Summer School course entitled: “Early programming: How early life shapes human development”. In its first online year, we were pleased to have 30 students from 18 countries join us for a series of interactive presentations, group activities, and stimulating discussions. Carolina de Weerth, Roseriet Beijers, Bonnie Brett, and Stefania Vacaru gave lectures about topics such as prenatal influences, infant attachment, cellular aging, synchrony, and the gut microbiota. Students also enjoyed a virtual lab visit, informal lunches with the instructors, and a fun and interactive social event. Although we missed spending in-person time with the students, we were pleased to have such a large, diverse, and engaging group of participants!
