Two postdoctoral positions are available in the Theoretical & Applied Geomechanics research group at the University of British Columbia. Both positions offer a two-year appointment with the possibility of a contract extension. Successful candidates will benefit from exposure to a dynamic international research environment and opportunities for various areas of professional development.

Position 1 Description

The selected candidate will be responsible for carrying out continuum-based numerical analyses with advanced constitutive models to address problems involving large deformations. The computational techniques of interest include Material Point Method (MPM), Finite Element Method (FEM), or Particle Finite Element Method (PFEM). Additionally, the candidate should apply machine learning techniques for conducting inverse analyses.

Position 2 Description

The selected candidate will conduct discrete element modeling (DEM), focusing on the monotonic and cyclic shearing response of granular soils. The study involves the assessment of various micromechanical descriptors of the granular system in loading scenarios of interest in soil mechanics. This work is crucial for advancing our understanding and application in constitutive modeling.

Selection Criteria

• Hold a PhD in Geomechanics, Mechanics, or a related field.
• Have expertise in one of the following computational methods: Material Point Method (MPM), Finite Element Method (FEM), Particle Finite Element Method (PFEM), or Discrete Element Method (DEM).
• Be well-versed in constitutive modeling.
• Have strong programming skills.
• Demonstrate excellent communication skills.
• Show the ability to work both independently and as part of a team.

Applications will be accepted until the positions are filled.

We are looking to recruit two outstanding PhD candidates on the development of novel stress sensors for a wide range of applications. Each of these projects is expected to last 3.5 years and will be fully funded.

The first project will develop and characterise the sensors for geotechnical engineering purposes, to measure stresses underground. The student will first design a family of sensors that are able to withstand harsh underground conditions, then characterise their response under calibrated stress-controlled tests, and finally verify the ability of the developed sensors to provide in situ, accurate dynamic information, and warning signs on the development of geotechnical failures. Prospective candidates for this PhD position are expected to possess a robust background in electronics and experimental mechanics, coupled with a keen interest in geomechanics. This project represents a thrilling opportunity to contribute significantly to industry capabilities.

The second project will advance those pressure sensors for soft underground robotics. In the first year the student will develop several prototypes at the University of Sydney (USyd) for different shapes of robotic heads and functionalities. Over the second year they will visit Dr Barbara Mazzolai’s group at the Italian Institute of Technology (IIT) to implement those sensors on robots inspired by worms and roots. Back at USyd on the third year, they will bring together the sensing and locomotion of the robots to explore burrowing dynamics in USyd’s fast x-ray facility. The recruited PhD student will be expected to have strong background in electronics and/or robotics and/or geomechanics. This is an exciting opportunity to actively contribute to international, multi-disciplinary collaboration.

For applications, please email your curriculum vitae, as well as the transcripts of your bachelor’s and master’s degrees. We aim to review applications by mid-February 2024.

Per- and polyfluoroalkyl substances (PFAS) are extremely persistent, harmful chemicals that have a complex transport behaviour in the environment. To assess risks associated with PFAS migration and the effects of remediation measures at contaminated hotspots, there is a great need for improved process understanding as well as modelling tools to predict PFAS transport in soil-groundwater systems. A promising technique to limit the spreading of PFAS further into the environment and to drinking-water resources is in-situ stabilisation with activated carbon.

In a larger Swedish project about mitigation of PFAS contamination, soil mixing and direct injection of activated carbon for in-situ stabilisation of PFAS are tested at contaminated sites and thereby large datasets of PFAS distribution in space and time including the effects of in-situ stabilization are generated. Modelling of the transport and adsorption processes is an important component for the interpretation and analysis of the results and their implications. However, existing modelling tools for PFAS fate and transport have not been thoroughly tested (in particular, against field data) and are in need of further development with respect to several PFAS-specific processes, such as; adsorption to air-water interfaces in the unsaturated zone, transformation of precursors and competition effects between different PFAS both concerning sorption to material interfaces and to sorbents.

The postdoctor to be employed will work with evaluation and development of modelling tools aimed to better understand the fate and transport of PFAS in the subsurface, and in particular, how this is affected by in-situ stabilisation. Modelling tools that can be relevant include among others MODFLOW-based solute-transport models, Hydrus, COMSOL, TOUGH2 or similar programs. The work will be performed under supervision of Prof. Fritjof Fagerlund at UU and is also a close collaboration with the Swedish Geotechnical Institute (SGI) and Geological Survey (SGU), where researchers at SGI also participate.

At the DMEX center for X-ray Imaging in Pau, France, we apply X-ray imaging to study a plethora of things. Recently, we have received support from Institut Carnot ISIFoR to hire two postdocs:
– One relates to the in situ recovery of Lithium and explores strategies to reduce the water consumption
– The second one, in collaboration with Carnot IFPEN, aims at developing a methodology for estimating the amount of natural hydrogen present in the North American intracratonic zone.

Both projects involve advanced X-ray tomography methods: in situ 4D CT in the first and spectral CT in the second project.
