This belief is the core of our work. We conduct research and offer trainings that support people of all ages in developing emotional intelligence skills. We do this work because the well-being and sustainability of our society depends on each of us using our emotions wisely. As a self-supporting unit within the Yale School of Medicine’s Child Study Center, our research and training is funded primarily through foundation and federal grants, corporate support, training revenue, and philanthropists. Our research is conducted in collaboration with experts in education, psychology, policy, and technology. Our goal is to design effective approaches for supporting school communities in understanding the value of emotions, teaching the skills of emotional intelligence, and building and sustaining positive emotional climates in homes, schools, and workplaces. We provide training to educational leaders, teachers, and school staff to support the systemic implementation of SEL (social and emotional learning) and foster those skills in all stakeholders in these communities, including in families and out-of-school time. We test and refine each element of our work, with the goal of leveraging emotions to create healthier and more equitable, innovative, and compassionate communities.
