Felipe Bachion de Santana

Soil Spectroscopy Technologist

Research Interests

My Researcher is focused on the development of a fast, robust, precise and accurate methodologies based on the use of MIR (DRIFT), NIR and XRF spectroscopy in tandem with Chemometrics and Machine Learning regression and classification algorithms (Random Forest, Cubistic, Support vector Machine, Artificial neural network, PLS, PCA and PLS-DA) to determine soil attributes used on Soil Science, i.e. Soil particle size (sand, clay and silt) %OM, pH, P, K, Al, CEC, among others.

My research areas are:

  • Chemometrics and Machine learning algorithms
  •  FTIR, NIR, XRF, Raman spectroscopy
  •  NIR, FTIR and Raman Hyperspectral imaging
  •  Handheld and portable spectrometers for field analysis
  •  Benchtop spectrometers
  •  Spectroscopy instrumentation

 

Current Projects

I am currently working under supervision of Karen Daly in the Terra Soil Project:

The aims of this project is produce new agricultural advice using geological data and soil samples, resulting in smarter agriculture, less environmental impacts and less wasted resources.

In this project I am using several spectral libraries combined with Chemometrics and machine learning algorithms to determine soil Particle Size, Soil Health and Soil Fertility Parameters.
