Sapna Sharma

Sapna Sharma is a Canadian scientist, and Associate Professor in the Biology Department, Faculty of Science, at York University, Toronto, Canada. Sharma holds the York University Research Chair in Global Change Biology[1] and heads the Sharma Lab for studies of human-induced environmental stressors.[2] She obtained her PhD[3] at the University of Toronto and held post-doctoral fellowships at the University of Montreal and the Center for Limnology at the University of Wisconsin–Madison.

As of 2021, Sharma is a recipient of the Provostial Fellowship[4] at York University and will be working with the provost and relevant members of the senior leadership on a project or initiative intended to advance one of the UAP (University Academic Plan) priority areas at an institutional level. Sharma's project, “Working Towards Equitable Access to Clean Water”, will combine student and staff efforts in raising awareness and identifying solutions to poor access to clean water around the world.[4]

Research

Sharma's research takes interdisciplinary, team science,[5] Citizen Science,[6] and data synthesis approaches to examine and predict the effects of environmental stressors on ecosystems. She has led the assembly, integration and analysis of large, long-term aquatic datasets that enables meta-analysis on a global scale. This approach has revealed how climate change is producing abiotic and biotic seasonal changes (phenology). Sharma's research group also examines how to improve the quantitative approaches used to generate these predictions.

Sharma's research often creates narratives around climate change that can make cultural and economic impacts more understandable for the general public. Her research on climate change and global warming has examined shrinking ice cover of freshwater lakes, and how fish distributions will be affected by a warming climate. The relation of ice cover loss to its impact on recreational ice skating in northern countries such as Canada, the United States, Sweden and Norway was widely covered in international media,[7][8][9][10][11] as well as local news outlets in communities directly impacted by her research.[12][13] Her work on the impact to freshwater fisheries projected that in Ontario alone climate change would impact the trout fishery in over 1,600 lakes by 2050, and 9,700 by 2100.[14]
