Hello! Welcome to my webpage
My scientific interests center on individual variation, population divergence, genetics and evolutionary theory, with a particular focus on the diverse mechanisms of adaptation and divergence. A main line of research is how individual Matching Habitat Choice can facilitate local adaptation, genotype-environment correlation, invasion of novel habitats, and experimental speciation. We studied this in a cryptic ground-perching grasshopper, combining descriptive field studies, manipulative experiments in the field and in our lab, determination of the quantitative genetics of colour, plasticity and habitat choice, and individual-based simulation modelling. More recently we started another exciting experimental test using Zebra finches. Additional consequences of Matching habitat Choice on individuals, populations and other species are being studied using kinds of /Drosophila/ fruit flies . And additionally we are finishing up studies on selection and adaptation in invasive african weavers after, as well as before, their introduction.”
