Ongoing Research

My current ongoing research includes:

  • Estimation of vegetation characteristics from hyperspectral data
  • Detection of clandestine graves
  • Remote sensing for border security
  • Application of remote sensing to ecosystem health
  • Long-wave infrared hyperspectral image analysis
  • High Performance Computing for remote sensing

  • Graduate Student Supervision

    I welcome MSc and Phd applications for three specific areas of research:

    1) Development of image processing algorithms using CUDA (previous experience with CUDA and GPGPU required)

    2) Bayesian Network analysis of historical data (previous experience with Bayesian Netoworks required)

    3) Distributed computing and remote sensing (previous experience with Torque Server, OpenMPI and one of Matlab, R, IDL or Octave required)

    Teaching

    I am currently teaching the following courses in Geography:

    GEOG 308: Prnciples of Remote Sensing

    GEOG 535: Remote Sensing and Interpretation
