Biographical details

Before joining the beelab I was a PhD student in applied mathematics at the University of Sydney. I studied the motion of large scale vortices, primarily using the efficient Contour-Advective Semi-Lagrangian (CASL) method.

Research interests

I study a broad range of problems in collective animal behaviour with the aide of mathematical models. My primary research interest is in studying the collective decision making process of swarms of various species of honey bee as they search for a site to establish a new colony. My principal study species have been the common cavity nesting Apis mellifera and the red dwarf honey bee A. florea. During my time with the beelab, I have also studied brood comb construction by species of Australian stinglees bees (Tetragonula) and helped develop methods for determining rules of interaction in moving groups of eastern mosquitofish (Gambusia holbrooki).
