I have been a science educator and teacher educator for 20 years. I teach courses, graduate and undergraduate, in science content and pedagogy. Most recently, as the Director of Professional Development for Washington University’s lnstitute for School Partnership, I have designed programs and professional learning experiences for K-12 teachers. I joined the CoLab in 2013, enjoying the collaborative space where the primary focus is the improvement of K-20 teaching using dynamic reflective tools.
