Fields of expertise
structural and material engineering; existing civil structures in particular bridges of high cultural value; fatigue, dynamics and structural behaviour of bridges; Ultra-high performance fiber reinforced concrete and composite UHPFRC-RC structures.
Mission
The activities as a Professor at the Swiss Federal Institute of Technology (EPFL) (since 1995) are motivated by the following vision :Methods for the examination of existing structures (Examineering) must be developed with the ultimate goal to limit construction intervention (and thus the clients expenditure) to a strict minimum. If interventions are necessary then their objective is to improve the structure (not just to repair it). This goal is in agreement with the principles of sustainable development.

UE F : Architecture and rehabilitation
This class aims to raise the students' awareness to the specificities of a renovation project. The Teaching Unit focuses on the relation between renovation demands and a broad architectural vision, with particular emphasis on sustainable development.
Safety and reliability
Notions of danger and safety as well as measures to master hazard situations relative to structures are introduced. Modelling of actions (loads) and verification principles of structural elements are introduced using deterministic and probabilistic approaches.
Existing structures : basis
Engineering methods inherent to existing structures (buildings, bridges, etc.) are introduced.
Existing structures : selected topics
Advanced examination methods are introduced to verifiy structural and fatigue safety of existing structures; intervention methods including new technologies are introduced to improve and modify existing civil structure.
Aesthetics of civil structures
A dictionary for the reading and description of aesthetic and cultural values of engineering structures and notions of art of structural engineering are introduced by means of bridges, tunnel portals, retaining walls, galleries as well as large infrastructure such as dams, roads and railways.
Fracture Mechanics and Fatigue of Structures
Determination of stress intensity factors and application of fracture mechanics to structures made of different materials.Ability to apply fracture mechanics to predict brittle fracture compute fatigue life of structural elements.Understanding of the influencing parameters methods to determine them
