San Francisco, CA, November 17, 2025 – The world of psychology and affective science mourns the loss of Dr. Paul Ekman, a towering figure whose groundbreaking research fundamentally reshaped our understanding of human emotion, facial expressions, deception, and compassion. Dr. Ekman, a celebrated psychologist and professor emeritus at the University of California, San Francisco, passed away peacefully at his home at the age of 91, surrounded by his loving family. His departure marks the end of an era defined by rigorous scientific inquiry and a profound dedication to unraveling the complexities of the human emotional landscape.
For over six decades, Dr. Ekman’s intellectual curiosity and meticulous observational skills were instrumental in elevating the study of emotion from a peripheral area of psychological inquiry to a central and vibrant field of research. His seminal work, often conducted in collaboration with colleagues and often extending into remote corners of the globe, aimed to identify universal patterns in human emotional expression. This pursuit led him to meticulously document and analyze facial movements, hypothesizing that certain expressions of emotion were innate and shared across diverse cultures, a concept that initially met with considerable skepticism but has since become a cornerstone of affective science.
The significance of Dr. Ekman’s contributions cannot be overstated. His research provided empirical evidence for the universality of a core set of facial expressions corresponding to fundamental emotions such as happiness, sadness, anger, fear, surprise, and disgust. This finding, supported by extensive cross-cultural studies, challenged prevailing theories that emphasized the purely learned nature of emotional expression and laid the groundwork for a more nuanced understanding of human psychology and biology. His work not only illuminated the commonalities of human experience but also provided a crucial framework for understanding the subtle variations and cultural influences that shape emotional display.
Dr. Robert W. Levenson, Ph.D., a distinguished professor in the Department of Psychology at the University of California, Berkeley, reflected on Dr. Ekman’s profound impact: “Paul brought his remarkable intellect, observational skills, and unflagging energy to illuminate the ways we express and feel our emotions and how they are embodied in our physiology. His research, theorizing, and ideas for how emotions could be harnessed in service of the greater good galvanized what was a small niche area of research into a vibrant and thriving research area that will continue to be hugely influenced by his work and vision.” This sentiment underscores the transformative nature of Dr. Ekman’s legacy, which has inspired generations of researchers and practitioners.
A pivotal development in Dr. Ekman’s career was the creation of the Facial Action Coding System (FACS). Developed in the 1970s, FACS is a comprehensive, anatomically based system for describing all observable facial movements. It provides a precise and objective method for quantifying facial expressions by breaking them down into their constituent "action units" (AUs) that correspond to the contraction of specific facial muscles. This system became an indispensable tool for researchers worldwide, enabling standardized measurement and comparison of facial expressions across different studies and populations. FACS provided a common language for scientists, therapists, and even law enforcement professionals to decode the intricate nuances of human facial communication.
Complementing FACS, Dr. Ekman also developed Micro Expression Training Tools, designed to help individuals identify fleeting, involuntary facial expressions that can reveal concealed emotions. These micro-expressions, often lasting only a fraction of a second, are particularly valuable in understanding subtle emotional shifts and can be indicative of deception or underlying emotional states. The training tools derived from his research have been widely adopted by professionals in fields such as security, law enforcement, psychology, and negotiation, enhancing their ability to assess truthfulness and emotional authenticity.
Dr. Ekman’s influence extended beyond academic circles, permeating popular culture and fostering global dialogues on empathy and ethics. His intellectual kinship and collaborative endeavors with His Holiness the Dalai Lama, a globally recognized advocate for compassion and peace, marked a significant phase in his career. This profound friendship and collaboration led to joint initiatives aimed at cultivating positive emotions and ethical conduct.
A testament to this collaborative spirit is the development of the Atlas of Emotions, an interactive online tool co-created by Dr. Ekman and his daughter, Dr. Eve Ekman, a contemplative social scientist and director of the Paul Ekman Group. The Atlas of Emotions provides a comprehensive framework for understanding the complex world of emotions, offering users tools to build emotional vocabulary, explore emotional triggers, and develop greater emotional insight. This project, along with the Cultivating Emotional Balance program, reflects Dr. Ekman’s dedication to translating his scientific findings into practical applications that promote emotional well-being and a more compassionate society.
Dr. Eve Ekman eloquently captured the essence of her father’s multifaceted legacy: “My dad’s commitment to rigorous science, love of discovery, and dedication to alleviating pain from destructive emotions were at the very core of his brilliant mind and accomplishments. However, his huge heart and ability to vulnerably share his own struggles with emotions were what made him beloved by so many. He was an incredibly loving dad – a lover of life and unrelentingly curious.” This personal perspective highlights not only his scientific brilliance but also his profound humanity and approachability.
Dr. Ekman’s insights into human behavior also reached a broad audience through his bestselling books, including “Emotions Revealed” and “Telling Lies.” These accessible works translated complex scientific concepts into engaging narratives, allowing the public to better understand their own emotional lives and the dynamics of deception. Furthermore, his work served as the scientific bedrock for the highly popular television series “Lie to Me,” which captivated millions by dramatizing the detection of deception through the analysis of facial expressions and body language. Dr. Ekman also lent his expertise as a scientific advisor to Pixar’s critically acclaimed animated film “Inside Out,” a groundbreaking cinematic exploration of human emotions that resonated with audiences of all ages and further solidified the public’s awareness of the science of emotion.
The Paul Ekman Group, now under the capable leadership of his daughter Dr. Eve Ekman, will continue to champion Dr. Ekman’s mission. The organization remains dedicated to making emotional awareness, empathy, and truthfulness accessible worldwide through science-based education and training, ensuring that his life’s work continues to inform and inspire future endeavors.
Dr. Ekman is survived by his children, Eve Ekman and Tom Ekman, and a vast and cherished community of friends and colleagues who were deeply touched by his intellect, kindness, and unwavering dedication.
