I am a PhD candidate working at Macquarie University, in Sydney. I have been practicing beekeeping for the last 8 years. One spring, I was helping a commercial beekeeper to evaluate his hives for the first time of the year, we opened dozens of hives that day without finding a single bee. They were all gone, they abandoned their brood and left the hive, leaving a frozen queen and a few workers behind. A few weeks later, we learned about the Colony Collapse Disorder. I felt that I had to do something for the bees. I stopped working on ants, moved from France to Australia, and started studying bees. The main goal of my PhD is now to understand why some colonies are collapsing. Over the past few years, an incredible amount of new sensors has been developed. I want to take this unique opportunity to understand how honey bee colonies grow and why they collapse.
