I am a Professor in the Department of Civil and Environmental Engineering at Carnegie Mellon University. My research focuses on probabilistic risk analysis and decision optimization, applied to civil infrastructures. Integrating fiber optic sensors  and using wireless sensors to measure strain and vibrations I look at methods to reliably mitigate risks and extend systems life-spans in civil systems. The analysis of this data and integrated reliability assessment tools can help stakeholders in their decision making processes towards a more sustainable use of resources.
