I work for Project Lead The Way, a U.S. non-profit that provides STEM programs to approximately 6,500 schools. I led development of our computer science pathway and co-wrote Computer Science and Software Engineering, our instance of College Board's CS Principles. I now collaborate with a team of writers who create K-12 computer science curricula, with high school teachers who lead professional development, and with specialists who create end of course assessments. I studied physics at M.I.T and taught high school for 15 years.
