Profile:

Sam Roy has expertise in dynamic socio-ecological systems, machine learning, biophysical modeling, stakeholder engagement, team science leadership, and student training and mentorship. His on-going sustainability research projects include: the Future of Dams and a new partnership with the Department of Energy to develop decision support tools for multi-objective management of US dams; a USGS/WRRI-funded project for development of computer-based tools to improve ecological and transportation safety management of tens of thousands of culverts underlying Maine’s vast road network amid changing climate and land use; and a coastal water quality project to identify potential policy change geared towards regulation of wild caught and aquaculture shellfish harvests. With colleagues in the School of Earth and Climate Sciences, Roy is also collaborating on research to generate a first-of-its-kind global model of bedrock strength and near-surface stress to make spatially-explicit predictions of landslide susceptibility via the integration of geostatistics, physics-based models, and deep learning algorithms.
