Research Projects

  • 2016-2021   Quantifying Vegetation Stress from the Leaf to Landscape Scale: Integrating Lab/Field Observations, Radiative Transfer Modelling, and UAV Hyperspectral Imaging System
    The objective of this NSERC Discovery funded program is to further the understanding of why and how vegetation stress induces spectral changes in Canadian grasslands and forests, particularly in response to altering climate conditions and intensified ecological disturbances. Deriving information on the major vegetation disturbance events is a high priority, given the lack of available data, ecosystem susceptibility to impact, and the magnitude of the potential impact downstream.
     
  • 2011-2016    Remote sensing of Canadian grasslands: using vegetation biochemistry to monitor grassland health 
    NSERC Discovery and Early Career Researcher Supplement funded project to explore and develop cutting-edge remote sensing methods to estimate spatially-explicit grassland biochemical properties at multiple spatial scales. These methods are essential for further work in carbon sequestration, climate change, ecosystem modeling and grassland ecosystem sustainability.

 

  • 2014-2020  Map trees infested by the emerald ash borer using high spatial resolution remote sensing data
    This is a project initially funded by UTM office of VP Research in 2013 and then recieved a 5-year Early Researcher Award from the provincial Ministry of Research and Innovation in 2015 to map EAB infestation in Ontario using field data, satellite images and UAV images. This work is collaborated with Credit Valley Conservation and Invasive Species Center. 

 

  • 2011-2015    Remote Sensing and Spatial Ecosystem Modeling (RSSEM) laboratory
    Funding from the Canadian Foundation for Innovation and the Ontario Research Fund to establish a laboratory that integrates remote sensing and ecosystem modeling approaches to study the vast Canadian grasslands at multiple levels (species, communities, ecosystem), spatial scales (local to regional), and dimensions (biophysical and biochemical drivers, human causes and climate drives). 

 

  • 2012-2016    Assessing forest biomass as a bioenergy feedstock: the availability and recovery of biomass in uneven-aged forests  (This is a collaborative project and PI is Prof. John Caspersen in Forestry at U of Toronto).
    The ecoEII funded project is to assess the potential for using forest biomass as feedstock for the production of bioenergy. The project builds upon preliminary work in both of these areas, including remote sensing (LiDAR) of potential biomass availability, as well as biomass harvesting trials designed to assess how much of the biomass can actually be recovered. We will also develop a model (BiOS) that will be made available to companies and agencies as part of FPInterface, a decision support tool for simulating the supply chain of forest operations. The model will help provincial agencies to better allocate wood supply to companies that can best utilize low quality wood and residues, including harvest blocks that would otherwise be passed over by companies seeking only higher quality wood.

 

  • 2011-2013    Using remote sensing to delineate and predict critical wetland habitat and modeling habitat suitability for the Blanding’s turtle (Emydoidea blandingii) in southern Ontario 
    The aim of this research is to use advanced remote sensing and spatial analysis techniques in conjunction with ecological modeling approaches to identify critical habitat characteristics for the endangered wetland-dependent Blanding’s turtle (Emydoidea blandingii). From this baseline information, further models will be developed through geospatial analysis of species’ movement in order to determine the connectivity of critical wetland and upland habitat leading to the identification of areas in need of protection, restoration or mitigation.
     
  • 2010-2012    Delineating the endangered vegetative species White Trillium (Trillium grandiflorum) and Wild leek (Allium tricoccum) using remote sensing and GIS technology in Gatineau Park 
    NCC funded project to evaluate the utility of multi-date remote sensing data for detection and mapping of endangered wild leek species in Gatineau Park in 2010.  NCC funded a second project in 2011 to explore and develop remote sensing methods to map the endangered White Trillium and to improve the accuracy of the Wild leek map from 85% to 90% in Gatineau Park, based on field survey, remote sensing data, and GIS tools.
     
  • 2010-2012    Object-based grassland biogeochemical modeling 
    ISTPCanada sub-contract from Prof. Xulin Guo (Geography, U of Saskatchewan) to establish an object-based grassland biogeochemical model and to test the model at different sites in Canadian grasslans.
