I am interested in the molecular mechanisms underlying the control of behavior in honey bees. I am particularly keen to understand
a) how the complex division of labor is regulated in a honey bee colony
b) how honeybees perceive gustatory stimuli
c) why some bees learn better than others
d) the role of biogenic amines and their receptors in regulating behavior
Using up-to-date molecular biological methods (e.g. quantitative real-time PCR), biochemical methods (immunocytochemistry, Westernblots), analytics (HPLC), CRISPR/Cas9 and a variety of behavioral assays (sensory responsiveness, learning, video monitoring, motor activity, RFID) we investigate the functions of selected genes in behavior.
On top of this basic research I am interested in more applied aspects of honeybee biology:
e) methods to reduce the Varroa load of honeybee colonies
f) side effects of novel insecticides on honeybees and interaction of insecticides and fungicides
g) differences in honeybee species and subspecies
h) modelling the impact of climate and landscape factors for honeybee colony development
