Alexander is Professor of Timber Structures at the University of Bío-Bío, Chile, and Associate Researcher at the National Center of Excellence for the Wood Industry (CENAMAD). Additionally, he currently serves as the Director of a Doctoral Program in Engineering applied to industry. The primary research line that Alexander has developed is related to the structural health monitoring of timber buildings—a highly relevant issue in countries with high seismic activity, such as Chile. A significant milestone in this research line was the construction of a five-story cross-laminated timber (CLT) building prototype on the campus of the University of Bío-Bío. Monitoring this building for two years has provided insight into the variation of its dynamic properties throughout different seasons and evaluated its structural performance during seismic and wind gust events. These results have contributed to updating Chilean regulations on wood design and construction, as well as to improving the community’s perception of this type of building.
