Isabel is a Product Manager of Subgrade Improvement at Terrafix Geosynthetics, which is a role that gives her the opportunity to be involved in the design stage up to project completion. Remarkable contributions of her role: deliver Value Engineering designs, address site challenges, and provide technical assistance, tests, and site visits. She graduated from URBE University in Venezuela in 2006 as an Industrial Engineer. She has worked for more than 10 years in civil engineering, supporting a wide variety of infrastructural projects in Venezuela, Spain, and Canada. Isabel was nominated by a fellow WIG member. When asked why we thought she would make a great spotlight, the individual said “she is incredibly bright, has an incomparable work ethic and because she is both female in a male-dominated industry AND a new Canadian, she works harder than anyone in her department (my opinion). She is always on, always ready to give more and ready to help.”
Great job Isabel! Thanks for being such a positive woman in the industry!
Dr. Arriaga has over thirteen years of academic and professional experience in the field of geotechnical and geosynthetics engineering. Her Ph.D. dissertation was titled: “Response of Geosynthetic-Reinforced Structures under Working Stress and Failure Conditions”. Research work included testing geosynthetic-reinforced slope models in a geotechnical centrifuge until failure to evaluate the stress distribution along the reinforcements. Dr. Arriaga’s experience spans public and private projects across the Western U.S. including transportation, earth retaining structures, dams and levees, waste containment, and methane mitigation.
