Biography

Dr Hamm graduated with BSc and MRes degrees from University College London and followed this with a PhD at the University of Southampton.   He has held academic and research appointments at the University of Twente (The Netherlands), University of Southampton (UK) and the University of Bristol (UK). He has also held visiting appointments at the University of Queensland (Australia) and RMIT University (Australia).  

Expertise Summary

Dr Hamm is a geoinformation scientist with specific interests in uncertainty, spatial data quality and the integration of heterogeneous datasets. He also has a background in geography and environmental science. He has particular expertise in geostatistical modelling of spatial and spatial-temporal data and the evaluation of uncertainty in environmental models and geographic data. He works with a range of environmental datasets including those from airborne and spaceborne remote sensing, in situ environmental sensors and environmental models. Applications include environmental monitoring (e.g., air quality, land cover), environmental modelling (e.g., species distribution modelling, biogeochemical cycles) and geo-health (e.g., neglected tropical diseases).   


Teaching

I teach undergraduate courses relating to geoinformation science, remote sensing and environmental analysis.  I have taught postgraduate courses in spatial data quality, geostatistics and remote sensing.
