Gautam Saw

About

Dr. Gautam Saw is a Spatial Analyst, GIS and Remote Sensing specialist, and environmental health researcher with expertise in geospatial analysis, spatial epidemiology, remote sensing, and environmental modelling. He completed a PhD through the University of Queensland (Australia) and the Indian Institute of Technology (IIT) Delhi, where his research focused on understanding the health impacts of residential greenspace exposure, air pollution, and climate-related environmental factors using large-scale population datasets and satellite-derived environmental indicators.

His research integrates Geographic Information Systems (GIS), remote sensing, spatial statistics, and public health to investigate environmental determinants of health, including hypertension, anaemia, low birth weight, and population health inequalities. He has extensive experience working with national health surveys, satellite imagery, environmental exposure modelling, and advanced spatial analytical techniques.

Beyond academia, Dr. Saw has worked across government, research, and consulting environments in Australia and India, supporting projects in environmental management, water resources, infrastructure planning, and geospatial decision support. His interests include environmental health, climate resilience, spatial decision intelligence, remote sensing applications, and the use of geospatial technologies to support evidence-based policy and sustainable development.
