Professor and Chairperson, School of Informatics

I am an ecological physicist who seeks to understand terrestrial ecological processes from a physicist’s perspective.

Electromagnetic (light) and mechanical (sound) waves serve as useful means of understanding ecological processes and characterising. In ecological parlance, sound-based studies translate as acoustic ecology. I have integrated hyperspectral remote sensing with vegetation and colour sciences to lay the foundation of ‘floral radiometry’. An important research focus of Floral Radiometry is to decipher the language of colour in nature.

Both the streams of investigations scales from individual to landscape levels and encompasses autonomous sensor-based data collection and analytics.

Research Interest

  • Ecological Informatics [Floral Radiometry, Acoustic Ecology]
  • Earth Observation [Optical Remote Sensing, Land Use Land Cover Dynamics]
  • Sustainable development [Technology Travelators, Conservation Psychology, Social inertia and Sustainability]
  • Conservation Biology [Biological Invasion (terrestrial plants), Sensor network for conservation].
  • Environmental Policy Analytics

Salient Scientific Contributions

  • Introduced the domain – Floral Radiometry by integrating remote sensing and colour science.
  • Pioneered research program and academic exercise in Ecological Informatics in India.
  • Integrated crop simulation model on a cloud platform.
  • Put forth a multi-dimensional retraceable geometric index of biodiversity.
  • Proposed the Soil-Line Technique for Relative Radiometric Normalisation of Optical Remote Sensed Data - (As part of doctoral research).
  • Introduced the parameter mean night temperature as a predictor variable of wheat yield models in India – (As part of doctoral research).

Points to ponder:

  • We do not have a definite answer to the question, why our ancestors abandoned their arboreal habitats. But it can be credited as the first evolutionary blunder, which has today precipitated as global environmental challenges staring at us.
  • Introduction of money qualifies as the second evolutionary blunder (though social). Since then man as a species has lost wealth to become rich.
  • Homo sapiens is perhaps the only species, which gives preference to males over females. This species has polluted the biosphere to a seemingly irrecoverable extent.
