Felix Jacobs
In August 2013, I had the chance to participate at the 5th International Young Geotechnical Engineers’ Conference (5th iYGEC) in Paris as a delegate supported by the German Geotechnical Society. This was a unique experience and motivated me to get involved with the issues of the ISSMGE. Since 2014, I serve in the ISSMGE’s Young Member Presidential Group (YMPG) and enjoy promoting the interests of young members.

Currently, I am a PhD student, working at the Institute of Geotechnical Engineering at RWTH Aachen University in Germany. My research focuses on geogrid reinforced soil. Herein, I work on a project regarding the pull-out behavior of geogrids, trying to develop a model for the complex interface behavior between geogrids and soil. Additionally, I carry out large-scale biaxial compression tests to directly investigate the compound behavior of geogrid reinforced soil with its characteristic interlocking and stabilizing effects.

Through my supervisor, Prof. Martin Ziegler, I am involved in the board for the German Recommendation for design and analysis of earth structures using geosynthetic reinforcements (EBGEO) and I am familiar with the European/Germans standards, especially regarding retaining structures.

Personally, I enjoy travelling (especially with my camper), and do lots of sports as soccer, kitesurfing, beach volleyball, and snowboarding in winter. If you would like to contact me regarding my research topics, the standards, or any other topic, feel free to reach me at [email protected].

Juan Ayala
ayalaI am currently part of the Young Member Presidential Group (YMPG), where I serve as Secretary since last year. I have my first close with the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) when I was majoring in Geotechnics in 2011, a day before the 5th international conference on earthquake geotechnical engineering in Santiago of Chile, the ISSMGE president of that time, Professor Jean-Louis Briaud call for a meeting to the young geotechnical engineers (or project of geotechnical engineers) present at the time, told as about the creation of the group (SYMPG at the time) was with the idea of increasing the attractiveness of the society to the younger generations of geotechnical engineers, and since then, that has always been the scope. Actually, thanks to the ISSMGE Foundation I was able to participate of that conference and present a paper in the International Young Geotechnical Engineers’ Conference in Paris last year, so thrust me when I say that the ISSMGE help me in my development as a professional. I earned my Bachelor and Master of Science degrees in Civil Engineering at Catholic University of Concepción with my dissertation of the experimental study of shear waves propagation in granular soils using bender elements in the oedometer equipment. I currently work in the rock mechanics area at Golder Associates Santiago office. In a more personal level I like to enjoy music, gliding and spend time with my 5 year old son.

Marcelo Heidemann
heidemannI am Civil Engineer. I am Brazilian and Member of YMPG for South America since 2011, when I have started my PhD course. I dedicated my Master course to investigate geotechnical behavior of tropical soils associated with landslides in Southern Brazil.

Tropical soils are also the theme of my PhD thesis, which I am developing in Federal University of Rio Grande do Sul, under supervision of Prof. Luiz A. Bressani. I am researching residual soil developed form granites in fault zones, related to mineralogical, petrological and geomechanical characteristics of these materials, and the behavior variability imposed by weathering in this scenario.

I work as Professor in Civil and Environmental Engineering courses since 2011. At this moment, I am Professor in the Engineering Mobility Center of Federal University of Santa Catarina, Brazil.  Additionally, in the last years I have been involved in some activities with Civil Defense, mainly in after-disaster situations related to landslides, as well as, few projects to the industry.

In terms of professional activity, my interest areas are geotechnical behavior of tropical soils, laboratory testing and landslides.
