John Lindsay has been a professor in the Department of Geography, Environment and Geomatics at the University of Guelph since 2008, having previously worked in the UK. His research explores the applications and techniques of geomorphometry, the field of quantitative analysis of surface topography. His current research explores multi-scale analysis in geomorphometry. Applications in spatial hydrology, geomorphology, and lidar remote sensing have been career-spanning research themes. The development and testing of novel spatial analysis techniques are central to Prof. Lindsay's research. As such, he develops open-source GIS software, Whitebox, as a platform for testing and disseminating these research contributions to practitioners. Prof. Lindsay is a past Vice President of the International Society for Geomorphometry (ISG).
