I am an educator, technology designer, and engineer with a passion for assessment and innovation. I am Program Director for Learning Catalytics at Pearson Education. In 2013, Pearson acquired Learning Catalytics, a company that I founded with Eric Mazur and Gary King that produced a cloud-based educational assessment and engagement platform. Learning Catalytics grew out of research work I engaged in as a Postdoctoral Fellow in Technology and Education at the School of Engineering and Applied Sciences at Harvard University. Previously, I was a software engineer at adap.tv, a video advertising startup in Silicon Valley. I received a Ph.D. from the Stanford University School of Education where I studied educational measurement and technology. I also hold an M.S. in statistics from Stanford University and a B.A. in mathematics from Cornell University.
