Research topic: Machine learning for geomembrane-sand interface analysis
Previous degree(s): The University of Brasilia, Brazil
Fun fact: I love soccer (watching and playing).
Description of research
My research focuses on geomembrane interaction with drainage and/or protection layers. Geomembranes are applied as barriers in canals, waste containment systems and tailings dams. For drainage and protection, geotextile or granular materials can be layered over a geomembrane. The interface interaction with the protective materials is crucial and adequate design of such structures prevents the sliding of the upper layer. Among several factors affecting the shear strength of this interface type, particularly for low normal stresses, the interaction represents a function of the geomembrane asperity and asperity geometry, or geomembrane surface roughness in general.
Other experience
I have three years of construction experience as a site engineer. I worked on the completion of residences, and commercial and high-rise buildings. I also worked as a consultant for a year on similar building design projects.
