I am an Associate Professor of Sociology at the Department of Sociology and Social Research at the University of Trento, where I am also the acting coordinator of the Hans Schadee Research Methods Center.
I obtained a PhD in Sociology from Ghent University (Belgium). Prior to joining the University of Trento, I was an Assistant Professor in Organisational Studies at VU University Amsterdam, a researcher/guest lecturer at the University of Groningen, and a Senior Lecturer in Organisational Behaviour and Human Resource Management at Surrey Business School (University of Surrey, UK) and the Programme Leader for the 4-year PhD in Management. I was also an associate member of Sociology/Nuffield College (Oxford University).
My research centers on social network analysis with a specific focus on methodology/statistics and applications in organisational settings. I am especially interested in how network relations (such as advice, trust and conflict) come about, and how they subsequently impacts outcomes (such as well-being, job satisfaction, turnover and individual and team performance).
I have worked on mathematical models for analyzing networks, on centrality measures, on imputation techniques for solving missing data problems and on methods for building social support typologies for ego-networks. In addition, I have applied exponential random graph models (ERGM/p* models) to study cultural participation, inter-organisational networks, and (co)sponsorship among US senators.
I have published a number of articles on social network analysis in leading social science journals, including Social Networks, Journal of Management Studies, British Journal of Social Psychology, Human Resource Management and the Journal of Mathematical Sociology.
Together with Martin Everett I was a guest-editor for a special issue on “Advances in Two-mode Social Network Analysis” in the journal Social Networks, and together with Nick Harrigan and Joe Labianca we guest-edited a special issue on “Negative and Signed Tie Networks” for Social Networks.
I co-authored the book “Analyzing Social Networks using R“. I have written on multilevel social influence in the book Multilevel Network Analysis for the Social Sciences, on models for network analysis in the Oxford Handbook for Social Network Analysis and on negative ties in the Sage Handbook of Social Network Analysis (2nd Edition).

I teach various courses on network theory, social network methods and social network analysis applied to organisations, sociology and political science, including at the Essex Summer School in Social Science Data Analysis (University of Essex), the Links Center (University of Kentucky) and Statistical Horizons (see my page on past and upcoming workshops).
I have also taught BA and MA courses on Organizational Theory, Organizational Behavior, Organizational Sociology, Human Reource Management, Survey Design and Research Methods.
