Associate Professor

Sapna Sharma

sharmaI am an Associate Professor in the Department of Biology at York University. My research interests include predicting the effects of environmental stressors on ecosystems at fine to broad spatial and temporal scales. I completed my PhD at the University of Toronto and post-doctoral fellowships at the University of Montreal and the Center for Limnology at the University of Wisconsin-Madison.

Alyssa Murdoch.  Alyssa is predicting the effects of multiple stressors (e.g., climate change, land use change, water quality) on northern fish populations.

 

 

Sam_Lake Erie
Samantha Stefanoff.  
Samantha is examining the drivers of water quality and nuisance algal blooms in the southeast shoreline of Lake Huron.  Samantha is now working for the Toronto Region Conservation Authority.

 

Thomas Thomas3Van Zuiden.  Thomas examined how changing climates may influence the distribution of coolwater fish species, such as walleye, in Ontario and their interactions with their competitors, such as smallmouth bass.  Thomas is currently a Data Manager & Analyst in the Sharma lab.

 

Miranda


Miranda Chen.
  Miranda investigated the effects of climate change on the distribution of coldwater fish populations and sportfish contaminants in top predator fishes in Ontario.  Miranda is currently a PhD student at the University of Tennessee.

 

Undergraduate Students

ÖSamantha Stefanoff Samantha examined changes in surface water temperatures globally  over the past 25 years in response to climate change through collaboration with the GLTC.  Samantha is currently an MSc student in the Sharma lab.

 

 

Sara Masood

Sara Masood.  Sara predicted the effects of climate change on woodland caribou populations in Ontario.  Sara is currently a MSc student at Western University.

 

 

 

GuangGuang Kun Zhang.  Guang examined the factors contributing to the decline of the wood thrush, a migratory bird population.  Guang is currently a MSc student at McGill University.

 

 

Lianna Lopez

 

Lianna Lopez.  Lianna predicted the effects of climate change on  novel potential competitive interactions between freshwater fishes.  Lianna is currently a MSc student in the Sharma lab.

 

 

Anam Qudrat.  Anam synthesized global water temperature data from 1985-2009 in collaboration with GLTC as an NSERC USRA.  Anam is currently a PhD student at the University of Toronto.

Rachel Cohen.  Rachel reconstructed records of ice breakup in Lake Simcoe from 1854.  Rachel is currently a MSc student at Wilfrid Laurier University.

Japnam Padda.  Japnam synthesized management strategies for woodland caribou populations in Ontario.  Japnam is currently a MSc student at the University of Toronto.

Gricelda

 

Gricelda Mendoza.  Gricelda examined the relative role of local weather and large-scale climate drivers on lake ice dynamics in Lake Mendota.  Gricelda is currently in medical school at Loyola University Chicago.

 

 

Rebecca Hough.  Rebecca developed invasive species and climate change outreach activities.  Rebecca is currently an undergraduate student at McMaster University.

Ibrahim Chaudry, Jessica Decker, Sana Iqbal, and Spyridon Hasiokas examined the effects of climate change on water temperatures in Wisconsin LTER lakes.

Post-doctoral Researchers

Ryan Sorichetti.  Ryan will be modeling climate-algal dynamics across Ontario lakes.  Ryan is currently a scientist with the Ontario Ministry of Environment and Climate Change.

Shekhar Biswas.  Shekhar predicted the effects of climate change on ecosystem services in Ontario lakes.  Shekhar is currently a post-doctoral researcher at Lakehead University.

Jonathan Ruppert.  Jonathan predicted the effects of climate change on woodland caribou populations.  Jonathan is currently a post-doctoral researcher at the University of Alberta.
