Academic Development Team

A/P Johan Geertsema
Director and Associate Professor

Johan Geertsema directs the Centre for Development of Teaching and Learning (CDTL). He oversees the Centre’s activities, providing strategic direction to foster scholarly approaches to academic development and align the Centre's practices and principles with the University’s priorities. Johan's background is in the Humanities—he has a PhD in English. He came to Singapore in 2001 to join the NUS University Scholars Programme, where he taught in—and later coordinated—the Writing and Critical Thinking Programme. Over the years he has developed a keen interest in higher education, especially in research-intensive contexts. Some of the topics on which he has been focusing include the ways in which teachers’ evidence-based reflection on practice made public can strengthen student learning outcomes; how to foster such scholarly work and use it to strengthen teaching at NUS; the distinction between education research and the scholarship of teaching and learning; teaching academies; and how to evaluate teaching achievement.

Dr Adrian Michael Lee
Deputy Director

Adrian Michael Lee is the Deputy Director of CDTL. He oversees the Centre’s Professional Development Programme-Teaching (PDP-T). He read Natural Sciences at Downing College at the University of Cambridge. For his work on small trapped ion clusters, he received the ICI Prize in Theoretical Chemistry. After graduation, he worked briefly at the British Antarctic Survey under the supervision of Prof. Howard Roscoe. He took up a PhD scholarship at the Department of Chemistry, University of Cambridge, under Prof. John Pyle FRS. A highlight of his doctoral studies was the development of a chemical forecasting methodology. In recognition of the use of this methodology during the ASHOE/MAESA international research campaign, he was awarded the NASA Achievement Award in 1995. He subsequently won a University Merit Award in 2000. Adrian continued his research in atmospheric science in Prof. Pyle’s research group until 2002, when he was awarded the Singapore Millennium Foundation Fellowship. This fellowship brought him to NUS, and his research under the fellowship centred on developing models to understand the economic cost of air pollution and global warming.
