Commitment to Impact

A core pillar of Tomas鈥檚 academic work is delivering measurable social, environmental, and economic impact. His research is designed to move beyond the theoretical and drive strategic policy changes.

Notable impacts include:

  • Electrical Network Resiliency: Conducted foundational research on enhancing the resilience of the electrical network in Chile. The strategic recommendations arising from these publications have been adopted and are currently being implemented.

  • Wildfire Mitigation Policies: Recently finalized advanced algorithms that provide data-driven recommendations on preventive landscape treatments to mitigate wildfire spread. These models were rigorously calibrated using real-world data from Texas and Australia. The next phase of this project involves applying these algorithms to real-life forestland data to help nations highly vulnerable to climate change craft strategic, effective landscape treatment policies.
