Short CV

Ralph Rippe is a tenured Assistant Professor at the Institute of Child and Education Studies, Leiden University. He is intrinsically driven to find (and develop, if required) the most adequate methods and models to deal with substantive or statistical issues, as to provide an accurate contribution to current knowledge.
His main interests lie at the intersection of statistics and genetics (and their combination) in child education, child behavior and child health. He is intrigued by how genetics and environment interplay in their influence on stress children or families (have) experience(d), on how children form (inadequate) attachment bonds, how groups of at-risk children might benefit from early interventions on literacy and numeracy, and how they form (un)healthy eating behaviors.

He obtained his MSc degree (cum laude) in Methodology and Statistics from Leiden University (2006), and his  PhD degree in Genetical Statistics in Social Sciences in 2012.

In 2013, he was awarded a Young Scholarship grant (CHF 120,000), together with dr. Huffmeijer and dr. Mileva-Seitz, from the Jacobs Foundation to work on differential dopamine susceptibility. He was co-applicant in a successful application for another grant (CHF 80,000) together with dr. Pluess and dr. Rhoades on marital quality and within marriage genetics. In 2016 he received a LUF grant of 5,000 for retrospective fraternity effects and benefits. In 2017 he received a Wellcome Trust top-up grant of GBP 30,000.

He has published over 20 articles, among which both first- and co-authorships in high-impact journals. Furthermore, he has international collaborations with researchers in the UK and the USA.
