Biography

4-H Youth Development Advisor for Marin, Sonoma, and Napa counties (2016-present)
Dr. Worker conducts extension education and applied research around youth development, informal STEM and computer science education, and volunteer development. Research activities focus on adapting, piloting, and evaluating youth development program models that integrate culturally relevant practices to engage culturally diverse youth, empower youth through consequential STEM and computer science learning, and support volunteer educators in improving their pedagogical practices to improve program quality. Recent projects have included youth participatory action research, developing curricula to strengthen young people’s computational thinking and positive ethnic-racial identity through computer science education, and promoting high school student college readiness through mentorships with college students and professionals. Programmatically, Dr. Worker provides academic leadership to 4-H clubs, summer camps, college readiness, teenagers-as-teachers, and youth participatory action research programs facilitated by 600 adult volunteers serving over 3,000 youth. Dr. Worker also chairs the North Bay Science Discovery Day, a free annual festival to spark young people’s curiosity for STEM learning.

Interim Assistant 4-H Youth Development Program Leader for Strategic Plan (October 1, 2022 to March 31, 2024)
Facilitate the activation and assessment of the UC 4-H Strategic Plan 2023-2028. Review strategic themes and goals, prioritize actions, and develop metrics to assess progress. Convene teams, or work with existing teams, to take actions to complete deliverables.

Previous Professional Experience

4-H Science, Technology, Engineering, and Mathematics (STEM) Coordinator (2009-2016): Worker managed professional and volunteer development for science educators, coordinated program and curriculum development and evaluation, and resource development. His work drew upon inquiry and experientially-based pedagogies grounded in a positive youth development approach. Worker co-authored two nationally peer-reviewed and published curricula, There’s No New Water! and Junk Drawer Robotics, along with a California curricula, iThrive: Leadership, Science & Me! 

State 4-H Program Representative (2001-2009): Worker provided leadership to the 4-H State Leadership Conference, 4-H State Ambassador program, 4-H Record Book, 4-H Technology Leadership Team, and other statewide 4-H adolescent leadership development and recognition programs. 

4-H Alumni
Worker is a 4-H alumni from Santa Barbara County (1991-1999). He served as a 4-H All Star (1996-1998; 4-H County Ambassador), earned his Emerald Star (1995), was a 4-H camp counselor, attended the 1998 National 4-H Conference, and served as a State 4-H Diamond Star (1998-1999; renamed now as "4-H State Ambassador"). In 1998, Worker co-founded the 4-H Technology Leadership Team, a group of youth and adults working to integrate technology into 4-H programming.
