About me

I am a PhD student in sexual selection working under the supervision of Dr. John Fitzpatrick. In this doctoral thesis, I will work with the pygmy halfbeak (Dermogenys colletti), a species showing a wide range of sexually selected traits including weaponry and ornamentation as well as associated behaviours of courtship and contest competition (pre-mating selection). Since female halfbeaks engage in multiple mating, there is also sexual selection after mating in the form of sperm competition and crypic female choice.

The planned projects include assessing condition dependence and trade-offs between sexually selected traits using two resource manipulation experiments. Futhermore, I will employ a quantitative genetics breeding design to examine genetic variation and covariation between sexually selected traits.
