Featured Projects

As a senior, practicing professional geotechnical engineer and engineering geologist, my core expertise covers infrastructure including earth-fill, zoned rockfill and gravity dams, hydropower headworks, headrace and pressurized tunnels (HRT), deep-cut excavations, canals, roads and bridges. As a technical expert I've worked in real-time face mapping, drill-and-blast optimization, kinematic analysis, seepage and deformation modeling, and as a manager I've led geotechnical QA/QC protocols, contract compliance, and interdisciplinary team leadership.
