Biography
Accomplishment of flights with hyperspectral, multispectral and thermal cameras on board manned and unmanned aerial platforms (UAVs, RPAS). Radiometric calibration of RGB, CIR, multispectral and hyperspectral cameras in optics laboratory. Spectral calibration of cameras in the laboratory by means of monochromator. Processing of images obtained by sensors on board airplanes to generate mosaics in radiance, reflectance and vegetation indices related to water and nutritional stress.
Research Interest
Within the scope of remote sensing, work on the simulation and validation of algorithms for estimation of biophysical parameters and biochemical constituents in vegetation from hyperspectral and thermal remote sensing. His work is based on the development and use of radiative transfer models simulating heterogeneous crop coverings, studying the effect of bi-directional reflectance on narrowband indices used for the detection of water and nutritional stress. His work on pre-visual indicators of stress, such as natural chlorophyll fluorescence, photochemical indexes related to the degradation of photosynthetic pigments, such as xanthophylls, and temperature estimation allow the early detection of vegetation stress from manned vehicles (AHS sensors, ALMOST,
