Introduction
I am a Canada Research Chair in Social Media Data Stewardship, Associate Professor at the Ted Rogers School of Management at Ryerson University (Canada), and Director of Research at the Social Media Lab. I am also a Member of the Royal Society of Canada’s College of New Scholars, Artists and Scientists; a co-editor of a multidisciplinary journal on Big Data and Society; and a founding co-chair of the International Conference on Social Media and Society. My research initiatives explore how the advent of social media and the growing availability of user data are changing the ways in which people and organizations communicate, collaborate and disseminate information and how these changes impact the social, economic and political norms and structures of modern society.
