My name is Dr. Randall S. Peterson, I’m a Professor of Organisational Behaviour at London Business School , and also serve as the founding Director of the School’s Leadership Institute.

I’m also a co-founder and Partner at TalentSage LLC. a company I set up to provide evidence-based science that accelerates leadership growth, bridging research to real-world impact..

My academic journey led me to earn a Ph.D. in Social Psychology from the University of California, Berkeley.

My professional expertise spans a variety of crucial areas within leadership and organisational dynamics. My work in research, teaching, and consulting primarily focuses on board effectiveness, understanding how CEO personality affects top team dynamics and performance, and the art of leading high-performance teams and organisations. I also specialize in leadership assessment and interpersonal skill development.

My research has been widely recognized, appearing in numerous leading academic journals around the world. Additionally, my insights have been featured in prominent publications for business leaders, including the Harvard Business Review, The Economist, Forbes, The New Yorker Magazine, and Zawya.

In July 2025 I received the Joseph E. McGrath Award for Lifetime Achievement in the Study of Groups from the Interdisciplinary Network of Group Researchers (INGRoup). INGRoup values and promotes diversity in theoretical and methodological perspectives for examining and understanding group processes and outcomes.

As co-founder of TalentSage LLC, my mission is to elevate leadership development through uncompromised academic rigor and evidence-based science. We move beyond superficial personality labels by leveraging empirically-backed psychometric tools, fundamentally rooted in decades of robust research, particularly the Five-Factor Model (Big Five). This provides our clients—individuals, teams, and organizations—with the deep, nuanced insights they need.

Our unique value lies in bridging the ‘knowing-doing’ gap: transforming theoretical knowledge into measurable, real-world behavioral change. We deploy intelligent, scalable learning solutions that ensure our data-driven strategies translate directly into high-performing talent and lasting organizational success globally. It’s about impact, guided by science.
