I enjoy working on a number of topics connected to applied mathematics and mathematical biology including: understanding the mechanisms behind collective animal movement, decision making and nest-site selection by honey bees, vortex dynamics, construction of amazing brood combs by stingless bees and the circumstances that allowed uniparental inheritance of mitochondrial DNA to become ubiquitous.
