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.
Africa – Middle East Regional Activities Leader
Jabulile Msiza is a member of the IGS Council. She holds a Master of Business Administration and two honours degrees in geotechnical and environmental engineering. In 2017 she was awarded the prestigious Consulting Engineers South Africa Young Engineer of the Year Award. Jabulile has gained around 15 years’ experience of geosynthetics at Jones & Wagener Engineering and Environmental Consultants in South Africa, where she leads the Waste Department.
Professor Chiwan Hsieh
Asian Regional Activities Leader
Dr. Chiwan Wayne Hsieh is a Professor in the Department of Civil Engineering of National Pingtung University of Science and Technology (NPUST). His research focuses primarily on engineering behaviour and applications of geosynthetics and construction materials. 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.
Dr. Laura Carbone
European Regional Activities Leader
Dr. Laura Carbone is an environmental engineer with over nine years’ experience in geosynthetics. Her PhD research focused on the interaction of geosynthetic – geosynthetic interfaces on slopes under static and seismic loading conditions. In 2012 Laura won the IGS Student Award. Laura co-founded the IGS Young Members Committee, and subsequently became chair. Laura has served on the IGS Council since 2016, initially as an invited member and from 2020 as an elected member. Since 2015, she has worked as a senior engineer at Huesker Synthetic in Germany, where she leads project designs in environmental engineering, with a special interest for landfill designs, slope stability and the remediation of contaminated sites.
Dr. Timothy D. Stark
Pan-American Regional Activities Leader
Dr. Timothy D. Stark is a Professor of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign (UIUC), USA. His research has focused on the static and seismic stability of geosynthetic-lined slopes and containment facilities, the effects of elevated temperatures, and long-term durability of geosynthetics with and without UV exposure. Dr Stark was elected to the IGS Council in 2020. He is also Technical Director of the Fabricated Geomembrane Institute (FGI), an industry-sponsored research organization comprising manufacturers, installers, consultants, regulators, equipment suppliers, and testing entities.
Communications Committee Leader
Sam Allen is the Vice President/Director at TRI Environmental based in Austin, Texas, operating worldwide. He began his career in the geo-environmental and polymeric materials testing fields and has broadened the scope of his involvement in materials engineering to include geosynthetics technology with specialization in laboratory testing operations. He has served as Chairman of ASTM International Committee D35 on geosynthetics and as Convener of Working Group 5 on durability within ISO TC221 on geosynthetics. Sam is an elected member of the IGS Council and has contributed to the work of IGS North America and several IGS Committees and Task Forces spanning the breadth of IGS’ activities.
Corporate Committee Leader
Francesco Fontana is the Managing Director of Manifattura Fontana SpA, one of the oldest manufacturers of needle-punched geotextiles in Europe, and has introduced many innovations for the applications of geotextiles and geocomposites. 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.
Dr. Takeshi Katsumi
Education Committee Leader
Dr Takeshi Katsumi is Professor at the Graduate School of Global Environmental Studies (GSGES), Kyoto University, Japan. He served as Assistant to the Executive Vice-President of Kyoto University for two years from 2012 October, and is currently Vice Dean of GSGES. His research interests cover environmental geotechnics, including waste landfills, remediation of contaminated sites, and re-use of by-products in geotechnical applications. Takeshi is a long-standing member of ISSMGE Technical Committee No.215 on Environmental Geotechnics, International Secretary of the Japanese Geotechnical Society (JGS), and a contributing member to the Central Environment Council of Japan. He has been involved in several recovery projects following the 2011 East Japan earthquake and tsunami.
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 Chair
Erol Tutumluer holds a B.S. (Bogazici University 1989), two M.S. degrees (Duke University 1991 and Georgia Tech 1993), and a Ph.D. (Georgia Tech 1995), all in civil engineering. He has been on the faculty of the department of Civil and Environmental Engineering at the University of Illinois since 1996. In October 2006, Dr. Tutumluer was recognized as the Paul F. Kent Endowed Faculty Scholar for his research accomplishments in the CEE department. Professor Tutumluer also serves as the Director of International Programs for the department.
