The Defence Research Network came about out of a conversation back in 2016 between PhD students who felt isolated in their respective South West institutions studying defence. We have formed a supportive community of researchers with diverse interests ranging from the history of airpower, counteirnsurgency, veterans families and cybersecurity. We have build up our presence on social media and held numerous face to face networking events as well as forming friendships and professional collaborations.

We connect our community primarily through Twitter where we encourage researchers to ask questions, comment on defence news and share recommendations about books, conferences and events and job vacancies.
