Gladimir Baranoski

Research Interests

Gladimir V. G. Baranoski is a researcher interested in the predictive simulation of light interactions with organic and inorganic materials. Although the main target of his work is the realistic modeling of material appearance for image synthesis purposes, his research efforts have also been directed toward the investigation of related problems in remote sensing and biomedical optics. Predictive models of material appearance have a wide scope of applications in these fields. For example, in remote sensing, they are used in the monitoring of the effects of adverse environmental conditions on crops and forests. In biomedical optics, they are used in the development of procedures and equipment for the prevention, screening and treatment of different medical conditions.
