Description of research
My research focuses on experimental and analytical evaluation of the application of geocells. Geocells are some of the most versatile geosynthetic types due to a vast range of uses. I am particularly interested in the measurement of the extraction capacity of geocells filled with concrete, which is a main concern in hydraulic applications such as canals, spillways, river protections and marine protections.
Another component of my research is related to the measurement and evaluation of the infiltration properties of geocells filled with concrete. A great deal of hydraulic works rely on this technology, and geosynthetic manufacturers have successfully pursued this application in practice but little is known about the performance of these structures. A third component of my research is the use of geocells for load support, which includes foundations, loaded platforms, ground improvement and roadways, both paved and unpaved. In this particular case, the use of transparent soil is highlighted as a novel approach to the evaluation of these applications.
Other experience
I have worked as a geotechnical engineer since 2008, and have been lucky to work at several companies in different countries for about 10 years before joining the Ph.D. program at UT. I also taught a few geotech courses, which I regard as my favorite job so far.
