This is me. My research interests are described on other pages linked to here, and at http://biology.queensu.ca/people/department/professors/grogan/
   

Qian Gu is an Ph.D. thesis student who started in September 2015.

"I am interested in exploring if ecological stoichiometry is useful in explaining impacts of environmental changes on arctic tundra plant communities. Do species differ in stoichiometric homeostasis characteristics for nitrogen and phosphorus contents, and if so, are these differences indicative of species responses to changes in air temperature, snow depth, and soil nutrient availability?"

Qian has a M.Sc. from the Chinese Academy of Sciences in Beijing, and is the recipient of Chinese Scholarship Council and Ontario Trillium Foundation International Ph.D. Scholarship support.

   

Meghan Hamp is an M.Sc. thesis student who started in September 2019.

"I am interested in the resilience of low arctic tundra ecosystems in response to climate change in terms of impacts on carbon fluxes, plant productivity, species composition, and belowground plant biomass. I am also interested in investigating the potential for warming to promote tree seedling establishment and shifts in vegetation dominance."  

Meghan was awarded a NSERC M.Sc. scholarship for 2019-2020.

 

   

Harris Ivens is an M.Sc. thesis student who started in September 2015, and successfully defended in December 2017. He is currently writing up his thesis as a manuscript for submission to a journal.

"I am interested in the possibilities of reducing fertilizer use in agricultural ecosystems by increasing and transforming greater amounts of the inherent nutrient supply in soils." 

Harris was a faculty member at Fleming College Ontario in their Sustainable Agriculture Program prior to joining our lab, and has his own consultancy business providing on-farm plant and soil assessments, management recommendations and financial advice. Harris's business e-mail is: harris@groundedbusiness.ca

Harris won the C.F. Bentley award for best student talk at the Canadian Society of Soil Science annual meeting in Peterborough in June 2017.

M.Sc. thesis title (2018): As above so below? -Impacts of water limitation on growth and nutrient accumulation of a crop plant and its soil microbes across a fertility gradient.

   

Mike Hann is an undergraduate honours thesis student from May 2019-April 2020. 


"I am interested in understanding how climate change will affect biogeochemistry in agriculture. In my thesis research, I am using recently developed methods to understand the fundamental mechanisms influencing water-mediated soil nutrient fluxes."
