I am a senior researcher at the Stanford Graduate School of Education and the director of professional development for Understanding Language , a research and professional learning effort focused on improving instruction and assessment of English learners and other diverse students. I consult for national and international teacher development projects that promote language, literacy, lesson design, and formative assessment practices. My current research focuses on developing classroom instruction that fosters high-quality oral language and constructive conversations across disciplines.

Professional Development 
I consult with schools, districts, counties, and states on the topics above. I also give PD presentations and keynotes.

Online Professional Development
I am also an instructor for online professional development courses that are offered by Stanford University. Please go to ell.stanford.edu for current course listings.
