In 2022 he received an honorary doctorate from Heriot-Watt University. He also received an honorary doctorate from the Technical University of Cluj-Napoca in 2022. At EPFL, he has held numerous leadership roles:

Director of LMS (2008–present) Director of the Civil Engineering Section (2012–2022) Member of the ENAC School Board (2013–2022) Director of the Doctoral Program in Mechanics (2008–2012) President of the EPFL Assembly and ETH Board representative (1999–2001) He has also served as Adjunct Professor at Duke University (2007–2024), Visiting Professor at Northwestern University (2022–2023), and held positions at Hohai University, University of Minnesota, Padova, and Montpellier. Laloui has collaborated or supervised numerous researchers including:

Prof. Alessandro Rotta Loria, Associate Professor of Civil and Environmental Engineering Northwestern University, Dr. Mathieu Nuth, Associate Professor at University of Sherbrooke, Dr. Bertrand François, Assistant Professor at Université Libre de Bruxelles, Dr. Alice Di Donna, Assistant Professor at University Grenoble-Alpes, Dr. Yafei Qiao, Associate Professor at Tongji University, Dr Roman Makhnenko, Assistant Professor University of Illinois, Dr. Anne-Catherine Dieudonné, Assistant Professor of Engineering Geology at Delft University of Technology Dr. Melis Sutman, Senior Lecturer Senior Lecturer The University of Edinburgh.

Research Laloui's research spans four principal areas.

Energy geostructures. His group works on foundations and underground structures that also function as ground heat exchangers, integrating structural and thermal engineering. Bio-cementation of soils. Laloui's research on microbially induced calcite precipitation for ground improvement led to the founding of the spinoff MeduSoil. Geological CO2 sequestration. His group studies the underground injection and long-term monitoring of CO2 as a means of permanent carbon storage. Nuclear waste disposal. Laloui works on coupled thermo-hydro-mechanical modelling for underground nuclear waste repositories.

Leadership and institutional contributions In addition to his academic career, Laloui is a leading voice in international geotechnical policy and innovation. As ISSMGE President, he has led initiatives focused on sustainability, youth engagement, and knowledge transfer. He chaired the Advisory Committee of the 2024 ECSMGE and is a member of the International Advisory Board for the 21st International Conference on Soil Mechanics and Geotechnical Engineering (ICSMGE) held in Vienna in June 2026. He has also contributed to numerous international expert groups including NAGRA (Swiss nuclear waste agency), the International Energy Agency, and the Swiss Competence Center for Energy Research.

Entrepreneurship and technology transfer Laloui is a founder or co-founder of several startups:

Enerdrape – geothermal panels for underground infrastructure Geoeg – energy geostructures for buildings Medusoil – bio-based soil stabilization Nesol – clean energy solutions His companies have won awards including the Swiss Top 100 Startups, Venture Kick, and AMAG Sustainability Challenge. He also developed the commercial design software Thermo-Pile, used globally in energy pile design.

Worked examples

Example 1 — a first encounter with Lyesse Laloui

Start with the simplest possible case. Write down what Lyesse Laloui claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lyesse Laloui before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lyesse Laloui ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lyesse Laloui

In research: Lyesse Laloui appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lyesse Laloui in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lyesse Laloui is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 births, Academic staff of the École Polytechnique Fédérale de Lausanne, French civil engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Lyesse Laloui outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
