Research

  • data reduction techniques
  • construction of sampling designs 
  • construction of experimental designs
  • parameter estimation

I contributed to different research axes about data reduction techniques, construction of sampling design and parameter estimation for non-gaussian distribution. I also acquired expertise in the construction of experimental design through teaching and helping other researchers to construct their designs. I dealt with different types of data: sensometrics, chemometrics, genomics, surveys, and Chlorophyll fluorescence imaging.
