Joseph Pechsiri

An expert in Industrial Ecology with a keen interest and extensive experience in assessing holistic system’s analysis based environmental performances. Contributions have been made in tourism, integrated coastal zone management, industrial ecology, handling/utilizing/ valorization of opportunistic/invasive biomass, and appraisals for aquatic photosynthetic biomass (e.g. micro-, macroalgae, and cyanobacteria) potentials from a systems perspective. Proficient in tools, such as LCA (E-LCA, S-LCA, LCC), TEA, EROI, and systems modeling. Additional experiences in microalgae growth experiment, coastal and savanna field ecology studies, and has collaborated with people at all levels of understanding while exhibiting patience, and integrity
