I received my PhD in Educational Psychology from the University of Colorado at Boulder (USA) in 1989 and then worked as Assistant Professor at the University of Northern Colorado before moving to Montreal in 2002, where I hold a position as Professor in Educational Psychology. I study diverse youths’ learning and identity work in science across time and space, in settings such as museums, afterschool and community programs through qualitative multi-sited ethnographies and discourse analysis guided by sociocultural historical theory. I am also interested in youth voice and participatory research methods and indigenous community based research. Gardening as a tool for learning and developing a relationship with nature and the land, youth activism tied to food production and sustainability issues are also of interest to me.
