Professor Stephen (Steve) Pointing is Professor and Director of Science at Yale-NUS College in Singapore. Steve earned his BSc and MSc degrees in microbiology from the UK. He won the prestigious Sainsbury Scholarship for postgraduate environmental research at the Bermuda Ocean Institute, and was awarded a PhD in marine microbiology in 1995. Steve gained his MBA in Education Management from Leicester University in 2010. Prior to joining Yale-NUS he held academic positions in the UK, Hong Kong, Japan and New Zealand.

Prof Pointing has spent over 20 years researching extreme environments finding microbial life where it should not exist, and this work has taken him all over the world from tropical hot springs to Himalayan lakes and Antarctic deserts. He has published some of the pivotal findings in his field and led several large international research projects. Prof Pointing is an award-winning teacher with a passion for making environmental issues exciting and societally relevant in the classroom. He is also very active in science communication and outreach, having made over 200 television and radio appearances commenting on environmental issues.

Professor Pointing’s research addresses fundamental questions in biogeography: the science of understanding spatial and temporal distributions for life. Current research is focused on resolving drivers of microbial diversity in desert environments, estimating intercontinental dispersal of microbes, and applied research to evaluate technology designed to search for traces of life on Mars.
