Her research thus far has concentrated on cryptic female choice - a form of post copulation sexual selection. To explore this poorly understood form of sexual selection, Patrice has used an externally fertilising species the New Zealand Chinook salmon (Oncorhynchus tshawytscha) as the model species.

The exciting results of this research show that:

(1) ovarian fluid (a viscous fluid that surrounds the egg batch) influences sperm behaviour and hence could be a mechanism of cryptic female choice and

(2) these results have now lead the way for further investigation to uncover the genetic bases for cryptic female choice in an externally fertilising species.
