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 ESSIVI GAGNON KOUDJIPh.D.  Sarah IshakPh.D.  Natalie KennedyPh.D.  Laura Jeanne Raymond-LéonardPh.D.  marylou meyerMembre employé(e) / Employed member  Tori MillerM.Sc.
