Nicole is an internationally recognised and trusted authority on navigating national security, crisis and emergency management challenges in environments of converged risk and threats. Formerly a regular instructor and guest speaker for NATO, Nicole is highly regarded for her work in distilling how groups influence the radicalisation and recruitment of their followers towards violent extremism; and how terrorist organisations deploy information and psychological operations in unconventional warfare. Nicole's depth of expertise across the online environment has also seen her lead work to better understand how information disorder is adopted by extremist groups. Nicole has a keen interest in AI and how online harms, particularly violent extremism, will manifest in the Metaverse environment.

Nicole is an Adjunct Lecturer at Charles Sturt University in the School of Terrorism and Security Studies. From 2020 to 2023, Nicole was also a Non-Resident Fellow at The Krulak Center at the United States Marine Corps University.

Nicole's doctoral thesis ‘The Radicalisation Cascade: Using Behavioural Economics to Understand how people are influenced towards Violent Extremes by al-Qaeda and ISIS’ offers a new way to consider the radicalisation process. A book based on this thesis, and the new model it offers for law enforcement, intelligence and professional P/CVE practitioners is forthcoming.

An early pioneer of using social media for OSINT in the law enforcement, intelligence and later military environments; Nicole's time serving with Australia’s Customs and Border Protection Service (now Australian Border Force) saw her work extensively in passenger air operations and intelligence environments.
