Sheryl's PhD project researched mitigation techniques for reducing marine mammal bycatch in commercial fishing gear. In particular, she was assessing the effectiveness of exclusion devices in trawl nets to reduce seal and sea lion mortality in Australian and New Zealand fisheries. Sheryl has a background in seabird ecology, wildlife population monitoring and environmental consulting, including assessments of the impact of fisheries bycatch on seabird, seal and sea lion populations.
