IGS Committees – Get Involved

The IGS Council is the governing body of the Society, chaired by the President.  There are eight Council Committees that are open to all IGS members to join. These include four Regional Activities Committees (covering Africa and the Middle East, Asia, Europe and Pan-America) and four Operational Committees (covering communication, corporate members, education, and young members). To find our more, click on the links below. If you wish to join one of our open committees please contact the relevant lead – they would love to hear from you!

You can also get involved by applying to join any of the Technical Committees.

In addition to the open committees, there are a number of closed committees covering awards, bylaws, finance and investment.

Professor Hsieh has served as the council member for the IGS Chinese Taipei Chapter for eighteen years. A Fellow of ASCE and CICHE, Council Member of the International Geosynthetics Society (2014-2020), Asian Committee Chair of IGS (2018-2022), and member of several international technical societies, Chiwan Hsieh has also been the director of GSI-Taiwan as a member of Geosynthetic Institute (USA) since August 1999.

European Regional Activities Committee

Patricia Guerra-Escobar

European Regional Activities Leader

Patricia Guerra-Escobar has worked in the field of geotechnics for over 20 years and is passionate about the role that geosynthetics play in civil engineering to deliver innovative, sustainable, and cost-effective solutions. Patricia has worked in several countries, starting in Colombia, before moving to France, and then Costa Rica, where she worked for eight years travelling extensively across Central American countries developing and expanding the use of geosynthetics in the region.

In 2010, Patricia moved to the UK and started to work with Geosynthetics Ltd. where she is currently the manager of the Engineering department. In addition, she is the current Chair of the IGS UK Chapter and member of the TC221 of ISSMGE. A focus of hers throughout her career has been supporting designers and contractors to use geosynthetics solutions in addition to educating the next generation of engineers, through mentoring and presenting at universities.

Pan-American Regional Activities Committee

Francisco Pizarro

Pan-American Regional Activities Leader

Francisco Pizarro is a Civil Engineer from Universidad de los Andes (Chile) with a master’s degree (MSc) in finance from ESE Business School (Chile). Most of Mr. Pizarro´s career has involved leading roles for world class geosynthetic manufacturers where he was been responsible for introduction, prescription, and commercialization of erosion control, reinforcement, and drainage products.

Mr. Pizarro is serving his second term as President of the IGS Chilean Chapter since March 2019 and was re-elected for 2021-2023. During his tenure, Mr. Pizarro and the Board have been encouraging the understanding and appropriate use of geosynthetics in Chile and the rest of Latin America with a series of short courses, workshops, and events, such as, Educate the Educators. Mr. Pizarro is also supporting creation of new IGS chapters in Bolivia and Guatemala with bylaws and company recruitment. In addition, Mr. Pizarro is leading a series of conferences in several Civil Engineer Schools in Latin America to promote the use of geosynthetics in infrastructure projects.

Operational Committees

Corporate Committee

Francesco has taken part in standardization activities with UNI, CEN and ISO for almost 25 years and has sits on the on the boards of AssINGeo, the Italian Association of Geosynthetics Entrepreneurs and EAGM, the European Association of Geosynthetics. He is also an elected member the IGS Council.

Education Committee

Dr. Timothy D. Stark

Education Committee Leader

Timothy D. Stark is a Civil Engineering Professor at the University of Illinois at Urbana-Champaign (UIUC). Dr. Stark has been conducting research on geosynthetics for 30 years. Dr. Stark is Technical Director of the Fabricated Geomembrane Institute, an industry-sponsored research organization at UIUC investigating geosynthetics for containment and other applications. Dr. Stark is also an Editorial Board Member of the two IGS journals. Dr. Stark has received a number of awards including: 2022 Cross USA Lecturer (ASCE), 2019 George H. Norman Medal (ASCE), 2017 Best Paper Award in Performance of Constructed Facilities Journal (ASCE); 2016 Best Paper in Geosynthetics International Journal (IGS); 2013 & 1998 Thomas A. Middlebrooks Award (ASCE), and others.

Young Members Committee

Dawie Marx

Young Members Committee Leader

Dawie Marx is a Graduate Research Assistant at The University of Texas at Austin, where he is researching soil-geogrid interaction as he works towards a PhD in Geotechnical Engineering under the guidance of IGS Past President Jorge Zornberg. Originally from South Africa, Dawie won the GeoAfrica Student Award in 2017.  During his undergraduate degree at the University of Pretoria, South Africa, Dawie worked at Jones & Wagener, specialising waste disposal facilities. Inspired by work on landfills, Dawie pursued research in geogrid reinforcing of landfill clay liners.

Publication Committee

Helmut Zanzinger

Publication Committee Chair

Helmut Zanzinger Helmut Zanzinger got his Dipl.-Ing. degree in geotechnical engineering from Karlsruhe Institute of Technology (KIT), Germany. He then worked as a researcher and consultant at LGA Geotechnical Institute for 14 years until he moved to SKZ – German Plastics Center, an independent testing and research company in Germany. He is currently the head of the ISO/IEC 17020 accredited inspection body of SKZ.

He has been active in the field of geoenvironmental and geosynthetics testing for more than 30 years with specialization in laboratory testing operations. His activities over the years include development of new testing procedures and methods, CQA on landfill lining systems and CE auditing worldwide.

His extensive research activities concentrated in the large-scale loading of drainage pipes, long-term internal shear strength of GCLs, cyclic loading of geogrids, strain hardening on PE-HD geomembranes, high-pressure autoclave testing on geosynthetics, testing and long-term monitoring of surface erosion control products. He has published more than 150 technical papers and held more than 100 lectures.
