The Editorial Board of Geotechnical Research extends a warm invitation for article submissions to a themed issue centred around ‘Recent advances in biogeoscience applications in geotechnical and geoenvironmental engineering’. Biogeoscience techniques, such as bioprecipitation (microbial-induced and enzyme-induced calcite precipitation), biomineralisation, biocementation, bioremediation and bio-geopolymerisation, have gained considerable popularity in the fields of geotechnical and geoenvironmental engineering.
