He has been the recipient of grants from the Australian Film Commission, the Australia Council for the Arts and Arts Victoria.
His installation works utilise a range of media including lenses and light, large scale mirrors, drawing and video to explore the deceptively simple fact of our presence in and perception of the world.
Leslie has often worked in collaboration with both artists and writers as a way of questioning conventional assumptions about authorship as well as working in response to a situation or location as a way of extending and testing the role of art practice and its outcomes. In recent years he has worked with New York based artist Natasha Johns-Messenger on six projects including XYZ-NYC held in New York in 2011.
For the past two years Leslie was a key member of Light Projects, an experimental project space in Melbourne which held over thirty exhibitions by local and international artists addressing themes of psychoanalysis and perception.
Leslie is a Senior Lecturer and Painting Programme Coordinator in the Department of Fine Art at Monash University.
