Dr. Henry Leitner is the Associate Dean for Information Technology and Chief Innovation Officer for the Division of Continuing Education (DCE) at Harvard University. He served as acting dean of DCE for three months, June-September 2019, and later served as Interim Dean of DCE from January 2020, until mid-July of that year. At Harvard Extension, he created the Master of Liberal Arts in information technology program. As Senior Lecturer on computer science, for over four decades Leitner has taught large introductory computer science courses and other advanced courses for Harvard Extension and Summer Schools, as well as at Harvard College. In 1999, he received the Petra T. Shattuck Excellence in Teaching Award, and in 2006 he was honored for 25 years of teaching at the Extension School. He co-founded Articulate Systems, Inc., a company that pioneered the use of voice recognition technology on the Apple Macintosh computer. Leitner has oversight responsibility for the pedagogical, software engineering, and technical support teams for online teaching and learning at DCE, as well as a growing collection of continuing and professional education courses that collectively enroll thousands of students annually. His current research is focused on innovation in online pedagogy and verifiable digital credentials, as well as the field of learning engineering, which involves the application of a principled set of evidence-based strategies to the continual redesign of educational experiences to optimize their effectiveness and efficiency. Leitner received his master's degree and his doctorate in applied mathematics from Harvard University.
