A.A. (Dré) Kampfraath
My research focuses on how interactions between organisms are influenced and altered, since this is a field of science that in my opinion should be better explored. A better understanding of these interactions can for example lead to better ways of pests control, better understanding of ecosystem functioning and co-evolutionary drivers.
Throughout my master I looked at the effects of pesticides on the interactions within a tritrophic system. In addition, I also studied the influence of combining fictionally different groups of organisms on decomposition. During this second internship we also developed a tool to assess the decomposition rate in aquatic environments called the DECOTAB.
During my PhD I am studying the loss of traits due to interactions between the springtail Folsomia candida and bacteria Wolbachia pipientis. This springtail has become dependent on Wolbachia for its reproduction. Using a combination of lab-experiments and genomics I search for the phenotypic and genotypic loss of traits that led to this obligate relationship.
