Joseph Trimble has spent his 30-year career conducting psychological and sociocultural research with indigenous populations, especially American Indians and Alaska Natives. He is a professor of psychology and professor in the Woodring College of Education at Western Washington University. He also holds positions at Colorado State University’s Tri-Ethnic Center for Prevention Research, the University of Alaska, Anchorage, and the University of Colorado Health Sciences Center.
During his fellowship year, Trimble will synthesize and organize information and findings to complete what could be the first full textbook of ethnic psychology. He will test several measurement models concerning cultural conceptual equivalence with different ethnocultural populations to explore the concept of cultural measurement equivalence. In addition to his work on the textbook, Trimble plans to complete two edited books, Counseling Across Cultures (5th Edition) and the Handbook of Racial and Ethnic Minority Psychology.
Trimble earned his PhD in social psychology from the University of Oklahoma. He received a Lifetime Achievement Award from the Society for the Psychological Study of Ethnic Minority Issues.
