Who We Are

We—Siri Ming, Evelyn Gould, and Julia Fiebig—are scientist-practitioners committed to promoting a collaborative and expansive view of ACT, RFT, and behavior analytic practice. This site is part of our efforts to bring together behavior analysts and other contextual behavior scientists committed to a rigorously systematic, functional contextualist, compassionate and values-driven approach to their practice and way of being in the world.

We hope to help in a collective effort to educate and influence the field, and support and empower the next generation of behavior analysts. Together, we can more deeply understand and apply the science to create more effective, nurturing, contextually sensitive environments and communities that reflect shared values of compassion, cultural humility, sustainability, and social justice.
