After studying how division of labour is regulated by queen pheromones in ants and in the honey bee, I became interested in honey bee health. I study the factors that determine colony health in honey bees at the Swiss Bee Research Center in Bern. I consider the effects of environment, human management and pathogens (such as parasites, viruses and pathogenic bacteria) and their interactions.
