Amirhossein Hassani

Amir is an Environmental Data Scientist with a PhD from the University of Manchester, where his research focused on modelling large-scale processes near Earth’s surface, particularly under current and projected climate conditions.

At NILU, his research is currently focused on enhancing the utility of novel low-cost sensor networks by integrating data from static, mobile, and wearable sensors with complementary datasets such as satellite remote sensing, air quality models, and citizen-contributed information.

His core competencies include machine learning, spatial analysis, and statistical data analytics, all of which he applies to investigate the physical, human, and policy dimensions of global environmental change. He is particularly interested in the drivers and impacts of changes in areas such as air quality, climate, urbanization, biodiversity, and ecosystem services. His work supports theoretically and empirically robust insights to advance knowledge on environmental change and its implications for society.

Amir Hassani has 38 publications at NILU:
