The Centre for International Peace and Security Studies at McGill University (CIPSS) and Université de Montréal (CEPSI) brings together researchers interested by issues related to international peace, security, global governance, international organizations, and international cooperation. It is one of few research centres in Canada to be both bilingual and based at two different universities.

The Centre was previously known as the Research Group on International Security (REGIS), a joint program in security studies between UdeM and McGill Faculty. REGIS was founded by T.V. Paul (McGill University) and Michel Fortmann (UdeM) in 1996. Currently, Jennifer Welsh is the Director of the McGill branch, while Theodore McLauchlin is the Director of the UdeM branch. Megan Bradley is CIPSS Associate Director. CEPSI/CIPSS now has 28 member researchers at the two universities, and each year, it welcomes numerous graduate students at McGill and at Université de Montréal.

CEPSI/CIPSS facilitates research through public activities such as the weekly CIPSS/CEPSI Speaker Series and the annual Graduate Student Conference. CEPSI/CIPSS’ Speaker Series runs weekly from September to April and seeks to offer opportunities for emerging and well-known IR scholars from across the world the chance to share their work, to create a forum for discussion and debate among members, to contribute to public debate on critical contemporary issues, and to give McGill and UdeM graduate students the chance to interact with researchers from other universities.
