About Me

I research and teach how leaders, teams, and organisations work together, with a focus on CEO personality, top management team interaction, board dynamics, leading diverse teams, conflict management, and the impact of individual personalities on group performance.

My research has been recognised with multiple awards, including the INGRoup ‘Lifetime Achievement Award’ and the Academy of Management’s ‘Best Paper’ award and ‘Most Influential Article’ award.

My work has also received recognition from the International Association of Conflict Management and Small Group Research for its contribution to understanding teams and collaboration.

What I Do

Research, Publications & Media

My research has been published in leading academic, scientific, and management journals, including Administrative Science Quarterly, the Journal of Applied Psychology, Harvard Business Review, and Sloan Management Review. Leading global media organisations have featured my work, including the BBC, The Economist, Financial Times, Forbes, Board Agenda, The New Yorker, and Zawya.

I have also published three books, most recently Disaster in the Boardroom: Six Dysfunctions Everyone Should Understand.

Academic Leadership & Global Experience

I hold a PhD in Social Psychology from the University of California, Berkeley. Before joining London Business School, I was a faculty member at Northwestern University and Cornell University’s SC Johnson Graduate School of Management.

I am a former Deputy Dean (Faculty), Faculty Director of the Leadership Institute, Subject Area Chair of Organisational Behaviour, Chair of the Ph.D. Programme, Research Ethics Committee Chair, and Vice President of the Campaign Committee of London Business School.

Throughout my career, I have been invited to teach and consult with organisations around the world, including ADNOC, Alcan, AREVA, Barclays, Chevron/Texaco, Deutsche Bank, Emirates Bank, E.ON, GIB, IBM, Lufthansa, Nestlé, Price Waterhouse Coopers, and Roche.

Teaching & Developing Future Leaders

I am passionate about developing the next generation of leaders and have been recognised for my commitment to teaching and mentorship, receiving the Academy of Management’s ‘Best Mentor’ award and London Business School’s ‘Excellence in Teaching’ award.

TalentSage Partner

I am also a Partner at Talentsage LLC, a company focused on using evidence-based tools and scientific research to accelerate leadership and talent development.
Through this work, I help individuals and organisations improve performance by applying data-driven approaches to learning, leadership, and team development.

Areas of Expertise

The crucial role trust plays in getting the benefits of task conflict.
Bringing together diverse perspectives to improve team performance.
The effects of CEO and team leader personality on performance.
Board effectiveness.

Working With Leaders & Organisations

I partner with leaders and organisations to address the challenges that affect collaboration, decision-making, and performance. Drawing on research into teams, leadership, and organisational behaviour, I help organisations understand what enables people to work together more effectively.

My work supports leaders in building effective teams, improving information sharing, managing conflict constructively, and bringing together diverse perspectives to make better decisions.

By combining rigorous research with practical application, I help organisations translate insights from psychology and behavioural science into meaningful improvements in leadership, teamwork, and organisational performance.
