EducationB.Sc. (1996) : McGill University in Biology M.Sc. (1998) : University of Toronto in Botany Ph.D. (2006): University of Basel (Switzerland) in Plant Ecology. ResearchDr. Handa's research interests are linked by the desire to understand the consequences of global change on ecosystem processes. She is interested in how changes such as rising atmospheric CO2 or urbanisation affect tree growth, as well as how changes in biodiversity influence litter decomposition and nutrient cycling in forest ecosystems.QCBS students Laura Jeanne Raymond-LéonardPh.D.  marylou meyerMembre employé(e) / Employed member Previous students (since 2009)Pierre-Marc BrousseauPh.D.  Javier Ibarra IsassiPh.D.  Laurent RousseauPh.D. Chelsea ArchambaultM.Sc.
