Research:
My main research interest is the neuroendocrine regulation of insect
development and, more general, the environmental-dependent expression
of alternative phenotypes in insects. I am particularly interested in
the regulation of caste (queen/worker) development in honeybees. In
this highly social insect species, I investigate juvenile hormone biosynthesis
regulation by brain peptides and signal transduction in the neuroendocrine
system.
