Dr Campion (BA (Hons 1 Class) PhD (JCU) is Lecturer of Terrorism Studies in the Master of Terrorism and Security Studies degree at Charles Sturt University. She is also an author, having published Australia's first comprehensive history of terrorism titled Chasing Shadows: The untold and deadly story of terrorism in Australia. 

She is the Joint Editor-in-Chief of Salus Journal, an independent peer reviewed policing journal; sits on the editorial board of Extremism  (United Kingdom) and the National Security Journal (New Zealand); and was a  guest editor of Social Sciences Special Issue on the Global Rise of the Far Right. 

Dr Campion is the Younger Visiting Fellow of the Centre for Researching Extremism (C-REX) at the University of Oslo, and contributor of the Australian Right-wing terrorism and violence dataset. 

Her research has focused on diverse terrorism threat natures in western democratic contexts. Her publications on right wing extremism have identified the extensive transnational and domestic networks; defined ideological systems and beliefs; critically examined the participation of women; and explored the contextual factors which has enabled its overall endurance.

Dr Campion's publications on left wing extremism have illuminated and provided nuance to a little understood - and contentious - threat nature. This has included an examination of "unstructured terrorism" as a historical strategy, through to contemporary resistance measures. 

Her other research has examined threats such as violent Salafi Jihadism, with respect to their presence in Australia and Indonesia, transnational connectivity, and lone actor violence. She also was the first to publish on underlying motivations for jihadist destruction of arts and antiquities, and to publish on jihadist response to the context created by COVID-19 (in conjunction with extreme right and left wing responses). 

Dr Campion lectures the History of Terrorism, spanning left wing, nationalist, and other terrorism threats. She developed and delivers Australia’s only subject on Right Wing Extremism and Terrorism. She also supervises HDR candidates specialising in terrorism and security studies. 

Dr Campion engages regularly with the broader counter terrorism community. She speaks to various domestic and international security audiences in an academic context. She also provides professional insight to state and federal professional security audiences in Australia on contemporary terrorism natures.
