This is a post-doc position in Liang Lei’s lab for a joint permafrost project collaborating with Ling Li’s lab and Sergio Andres Galindo Torres’s lab.
Introduction of The Lab/Research Field
Dr. Lei’s research on porous media features temperature, pressure and stress control, pore-scale insights based on micro-CT technique integrated with conventional testing, multi-physics experiments and theoretical analysis. Targeted areas include: (1) particulate material and porous media under abnormal conditions and their interaction with pore constituents; (2) energy, marine, and resource geo-engineering; (3) permafrost and outer space sediments; (4) natural gas hydrates and their hosting sediments; (5) massive energy storage; and (6) multi-phase flow and crystallization in porous media.
In the week from 11 to 16 October 2021, the second edition of the Mediterranean Phd School, organized by the Department of Civil, Building and Environmental Engineering of the University of Naples Federico II, will be held. This year, the event will focus on the theme “EUROPEAN GREEN DEAL. CONTRIBUTIONS FROM CIVIL, ARCHITECTURAL AND ENVIRONMENTAL ENGINEERING”; it will be held online and will be completely free.
As regards engineering geology and geotechnical engineering, lectures will be given by proff. Paolo Fabbri (Padua University), Antonio Gens (UPC Barcelona) and Lyesse Laloui (EPFL Lausanne). Works will end with a round table coordinated by prof. Gianpiero Russo (University of Naples Federico II).
Phd students, in addition to attending lessons, will participate in application activities and may request to present scientific contributions related to the theme of the School. Prizes for the best presentations are planned.
More information is available on this flyer.

On Thursday 22 July 2021, at 15:30 CET, Dr. Simona Guglielmi, Post-doctoral researcher at University of Naples “Federico II”, will be delivering the following webinar:
“Microstructural changes underlying the compression behaviour of clays of different sensitivity”
The webinar is organised by the Geotechnical Research Group of DICATECh, Politecnico di Bari, Italy, and will be held on Microsoft Teams. No registration is required, participants can join the event by clicking on the following link:
Please see the attached file for further details.
Laboratory experiments dealing with interactions between granular materials and geomembranes will be conducted in the project. Then DEM modeling of the experiments will be designed following a “digital twin” approach. The objective of the PhD is to precise the local processes of geomembrane failure subjected to puncturing actions and precise the design of protective layers of geotextiles. More information in the attached proposals (french and english).
The PhD project will be conducted at INRAE in Aix-en-Provence (France) and may start as early as October 2021 (with some flexibility).
Applications (CV and cover letter) should be sent to Guillaume Stoltz (email@example.com) and Antoine Wautier (firstname.lastname@example.org).

The University of Strathclyde is currently recruiting for a funded PhD project in subsurface engineering.
This lab-based project will focus on developing micron- and nano-scale technology to create novel grouts for enhancing the hydro-mechanical properties of the subsurface. During the project, different subsurface engineering applications will be scoped with the aim of targeting net-zero carbon related opportunities such as energy storage (compressed air, hydrogen), geothermal energy, and carbon sequestration. The candidate will be joining a research group with a track record in developing novel grouts, and in using advanced techniques such as X-ray micro CT and bespoke designed mechanical testing equipment to characterise and evaluate the grout effectiveness.
The deadline for the application is the 13 August 2021. For more details or information on how to apply, please see this file.
The preliminary programme of the ALERT Doctoral School 2021 in Aussois/online is now available. Be aware that changes can still occur. The programme of the Workshop will follow soon.

“Constitutive Modelling in Geomaterials“
Coordination: prof. Claudio Tamagnini [CT] and prof. David Mašín [DM]
Lecturers: prof. Ivo Herle [IH], prof. Cristina Jommi [CJ] and prof. Claudio di Prisco [CDP]
Irrespectively of fast development of approaches for the analysis and design in geomechanics based on the methods for discontinuum (such as discrete element method), analysis of continua based on mesh or fast developing particle-based meshless methods still represents major means of numerical analysis in geomechanics. At the very core of such an analysis is a constitutive model: mathematical relationship converting the peculiar behaviour of particulate material, governed by the interactions between individual particles, into the behaviour of continua. As such, a properly selected and calibrated constitutive model has a critical effect on the outcomes of geotechnical simulations.
This school aims to introduce the students into the broad field of constitutive modelling of particulate materials with special emphasis on the behaviour of soils: after the introduction consisting of summary of basic features of soil behaviour, they will be introduced into fundamentals of constitutive modelling, followed by more detailed description of various modelling approaches – from the basic elastic and elasto-plastic models to more advanced frameworks of hardening plasticity, bounding surface plasticity, generalised plasticity and hypoplasticity. The second day will be focused on various specific more-advanced topics, such as simulation of small strain stiffness and cyclic loading, modelling of unsaturated soils, meta-stable structure, breakage, thermal effects, chemical effects and time and rate dependence, including formulation of finite-deformation plasticity and macroelement modelling. The last day is devoted to steps needed for adoption of models in numerical analysis tools, namely to their implementation in finite element codes. Finally, in practical hands-on sessions, students will train calibration using real experimental data themselves, using both manual and automatic freely-available calibration tools.
