Post-doctoral researchers

Dr. Dimitrios Terzis

Dr. Dimitrios Terzis is a Scientist at the Soil Mechanics Laboratory of EPFL and Science entrepreneur. He obtained his Ph.D. in Mechanics at EPFL in 2017 with his doctoral dissertation titled “Kinetics, Mechanics and Micro-structure of bio-cemented soils”. He holds a M.Sc. in Civil Engineering from the Aristotle University of Thessaloniki, Greece (2014) and between 2011-2012 he studied Civil Engineering at École Spéciale des Travaux Publics, du bâtiment et de l’industrie (Paris, France) as an exchange student. In 2017 he received the “Earth and planetary Sciences award” of the faculty of Environment, Architecture and Civil Engineering of EPFL for his publication titled “3-D micro-architecture and mechanical response of soil cemented via microbial-induced calcite precipitation”” published in Scientific Reports, a Nature research journal. He is the recipient of an EPFL Innogrant, a prestigious innovation grant, which supported his tech transfer venture in 2018.

Dr. Daehyun Kim

Dr. Daehyun Kim is a Scientist at the Soil Mechanics Laboratory of EPFL. He joined the BIOGEOS team after completion of his Ph.D. dissertation at Arizona State University (US) in October 2019. His dissertation is entitled “Pore-scale Study of Bio-mineral and Bio-gas Formations in Porous Media”. He holds a M.Sc. (and B.Sc.) in Civil & Environmental Engineering from Yonsei University (Korea) with a thesis titled “A Study on the Thermal, Electrical, and Hydraulic Conduction Phenomena for Hydrophobic Geo-materials”. His research background and interests closely align with the development of bio-mediated & bio-inspired geotechnical solutions for environmentally friendly sustainable construction techniques.

Alexandra Clarà Saracho

Alexandra is a Scientist at the Soil Mechanics Laboratory at EPFL. She is in the final stages of obtaining her Ph.D. in Geotechnical Engineering from the University of Cambridge (UK). Her Ph.D. Thesis is entitled “A multi-strain study on the erosion performance of MICP-treated sands”, product of an industry-academia collaboration between JOGMEC, University of California, Berkeley (USA), Hiroshima University (Japan), and University of Cambridge. She holds a MRes in Future Infrastructure and Built Environment (2016) also from the University of Cambridge and a Civil Engineering degree from Universitat Politècnica de Catalunya (Spain, 2015), the final year of which was spent at EPFL as part of the Laboratory of Hydraulic Constructions. Her Ph.D. research has opened up promising avenues for designing bio-reinforced geo-materials that capitalise on the different particle bond mechanical properties offered by different CaCO3 phases, and highlighted the great potential of alternative instrumental techniques, commonly employed in other fields, for use in MICP characterisation. She is now looking to employ this knowledge in the upscaling of tailored bio-cement treatment on a commercial scale.


Ph.D. Students

Ariadni Elmaloglou

Ariadni Elmaloglou is a Ph.D. Candidate at the Laboratory of Soil Mechanics of EPFL. Ariadni completed a M.Sc. thesis entitled “Characterization of contaminated sites with the DC/IP method: Rødekro case” in 2017, as part of her M.Sc. in Environmental Engineering at Technical University of Denmark. She also holds a 5-year diploma in Civil Engineering from National Technical University of Athens, with specialization in Geotechnical Engineering.

Ray Harran

Ray Harran is a Ph.D. Candidate at the Laboratory of Soil Mechanics (LMS) of EPFL. Before joining the LMS, Ray defended his master thesis entitled “Decision Aids for Tunneling – A Catalogue for application to small tunnels”. His work was accomplished during an exchange between EPFL and the Massachusetts Institute of Technology (MIT) in the USA, where he was hosted in the rock mechanics lab of Prof. Herbert Einstein.

Benedikt Moser

Benedikt Moser is a Ph.D. Student at the Laboratory of Soil Mechanics (LMS) at EPFL. Benedikt studied Civil and Environmental Engineering at the Technical University of Vienna, specializing in Geotechnical Engineering with an emphasis on Numerical Simulations. His M.Sc Thesis discusses the possible applications and limitations of Synthetic Rock Mass (SRM) models for stability analyses of rock slopes, accomplished in cooperation with the Wildbach- und Lawinenverbauung Tirol.
