Dr Anya Leenman

Junior Research Fellow


MSc (Auckland); PhD (UBC)

Academic Background

I studied Geography, Environmental Science and Music at the University of Auckland and continued on for a BSc(Hons) and MSc in Geography. I then moved to Vancouver for my PhD at UBC.

Research Interests

I am a fluvial geomorphologist with interests in contemporary river processes. I use satellite observations to delve into the dynamics of rivers around the world, with a particular focus on river responses to hydroclimatic extremes. In the past, I have conducted small-scale lab experiments to model the behaviour of multi-threaded mountain streams, and combined drone photography with computer-vision methods to understand river dynamics at annual-to-decadal timescales.
