  • I am interested in the relative roles of different evolutionary forces (i.e. natural selection, pre- and postcopulatory sexual selection) on phenotypic variation, with a particular focus on sperm traits. The overwhelming diversity in spermatozoa across the animal kingdom is an evolutionary conundrum. Yet, most research has been restricted to study systems that exhibit design uniformity. Using both comparative and experimental approaches, I investigate the evolutionary causes and consequences of sperm form and function variation in a group where both sperm and mating biology have unparalleled diversity — the tardigrades.
