Dr Alexandra Clarà Saracho is a Research Fellow and Affiliated Lecturer in Engineering active in the field of bio-mediated soil processes and sustainable geotechnical engineering practices. She is particularly interested in understanding the microbial processes involved in the formation of calcium carbonates by soil-dwelling bacteria, and the relationship between the microstructure of the minerals they form and the macroscopic hydro-thermo-mechanical response of carbonate cemented soils. At the intersection between the biological sciences, materials chemistry and engineering, Dr Clarà Saracho addresses key questions of sustainable and resilient infrastructure, where fundamental research, physical modelling and technology transfer can be integrated in collaboration with industry.
