Ejaculate adjustment and nonconsensual sexual activity
With: Andrew M. Holub, Todd K. Shackelford

Investigating whether some men produce higher-quality ejaculates when primed with stimuli depicting the nonconsensual sexual activity.

The sociosexuality of romantic couples
With: Tara DeLecce

Investigating the way relationship dynamics may or may not influence ejaculate quality.

A cross-cultural investigation of voice modulation in professional versus personal social contexts
With: Katarzyna Pisanski et al.

In a cross-cultural sample of 300 men and women from six countries, we test whether vocalisers differentially modulate key vocal parameters as a function of the professional hierarchical status and sex of the listener.

Investigating Plasmodium falciparum proteins
With: Fabia Battistuzzi et al.

Among the many genes in Plasmodium falciparum, some are more likely than others to allow the pathogen to successfully infect its host and escape the immune system. We are interested in understanding the evolutionary mechanisms that drive changes in these genes that allow plasmodium to be a very effective pathogen. Once these mechanisms are known, we may be able to manipulate these genes to improve drug and vaccine success against malaria.
