Leon van Paassen is associate professor at Arizona State University (ASU) and senior investigator at the National Science Foundation Engineering Research Centre for Bio-mediated and Bio-inspired Geotechnics (CBBG). He received a master's degree in applied earth sciences in 2002 from Delft University of Technology with a specialization in engineering geology. During and after his graduation, he worked several years as a geotechnical engineering consultant at IFCO Foundation Expertise and research institute Deltares. In 2009, he obtained his doctorate in applied sciences at the Department of Biotechnology of Delft University of Technology. His thesis on Biogrout: Microbially induced carbonate precipitation as ground improvement method resulted in several publications, patents and was awarded with several national and international awards. In his research, he integrates the fields of environmental biotechnology and geotechnical engineering, aiming to develop sustainable solutions, which improve resource efficiency and reduce the environmental impact of civil and mining engineering industry.
