Research interests

Christelle is a civil and mechanical engineer, working on geosolutions for climate change. Her research activities include soil-structure interaction and scour protection for wind energy applications and sensing and monitoring for early-warning of climate-change induced geo-hazards. Her current research is mostly focused on two axes:

Design of Foundations for Offshore Wind Turbines:

Christelle has over a decade of expertise in the development of improved and robust guidelines for the design of monopile foundations for offshore wind applications. She has worked on a range of projects, addressing:

  • Capacity: Christelle was the leading research assistant for the PISA2 project. PISA2 is a Joint Industry Project run through the Carbon Trust and follow-up from Fleming award winning PISA project (2013 - 2016). This project enabled the development of the PISA method, a simple, and fast 1D numerical tool for the design of offshore monopile to lateral loads. PISA2 aimed at expanding the PISA design method to new soil types, including layered soil profiles.
  • Long-term quasi-static cyclic loading: offshore wind piles accumulate permanent deformations due to the repeated action of waves and winds (principally). This phenomenon is called ratcheting. Christelle's work involved the development and calibration of a constitutive model - HARM (Hyperplastic Accelerated Ratcheting Model) - that captures this behaviour in a simple, fast yet rigorous way.
  • Earthquake Design: Current deployment of offshore wind farms in Asia and North America require robust design to seismic loads. Christelle's current work involves developing an experimental database evidencing the behaviour of offshore wind piles to earthquakes, in particular in liquefiable soils.

Christelle's research projects are conducted in close collaboration with offshore wind industries, such as EDF, Orsted, ARUP and HR Wallingford.

Sinkhole Early Warning Detection:

Christelle's recent work involves the development of an early warning system for the detection of sinkholes formation at depth. Sinkhole failures are among the most common and disruptive shallow geohazards.

A sinkhole is a depression formed at the ground surface, caused by the formation of a cavity at depth, with progressive collapse of the ground towards the surface layer.  Ongoing climate change raises the likelihood of sinkhole formation and sinkholes are an increasingly common geohazard and financial burden for society. Sinkholes can develop over extended periods, with measurable ground deformation developing over the course of several days, weeks or even years before the eventual collapse.

Christelle leads a project aiming at using Distributed Fibre Optic Sensing and Satellite Monitoring to inform on early formation of sinkholes and thus offer opportunity for remedial action to prevent catastrophic failures.
