THE STAFF
Among the 70 engineers who work for HCItasca worldwide, the following are ITASCA CONSULTANTS, S.A.S.:
Daniel BILLAUX
d.billaux@itasca.fr
Managing Director
Dr. Billaux's expertise is in numerical modeling, fractured rock hydrogeology and geomechanics. He has developed and applied numerical models to simulate the flow of water in fractured rock. He has been a program manager for projects in the area of nuclear waste storage and geothermal energy and has provided consulting on many mining and civil engineering projects.
Caroline DARCEL
c.darcel@itasca.fr
Hydrogeological modeling
Dr. Darcel has worked on geometrical characterization and hydrogeological modeling of fractured media. She has focused on the multi-scale properties of network fractures, characterized by power-law fracture size distributions and fractal spatial density distributions. Dr. Darcel also has developed unsaturated flow codes.
Fabian DEDECKER
f.dedecker@itasca.fr
Numerical modeling & soil and rock mechanics
Dr. Dedecker is a civil engineer with over 8 years of experience in the geotechnical and mechanical engineering fields. His areas of specialization are nuclear-waste disposal research, the static and dynamic stability of rock dams, and the study of flow in fractured rock masses, based mainly on discrete approaches.
Yoann Hebert
y.hebert@itasca.fr
Numerical modelling in geomechanics.
Yoann Hebert has worked on the determination of the mechanical properties of a soil by inverse analysis, during the digging of a tunnel in Toulon (France). He has performed a stability analysis of a 30 years old cavern, and participated in mechanical study of a rock fill dam, constructed above a concrete gallery.
Romain LE GOC
r.legoc@itasca.fr
Numerical modeling in hydrogeology
Mr Le Goc works on numerical modeling of fractured media. He is a graduate engineer in computer sciences and has gain experience in a unit of research in hydrogeology (France). He is skilled in grasping natural media issues and developing efficient numerical models. He has worked on the inverse problem in hydrogeology for highly channelled flow in heterogeneous media. He has participated in discrete fractured network modeling for a nuclear-waste disposal site (Sweden).
Wenjie SHIU
w.shiu@itasca.fr
Numerical modelling by a discontinuous approach
Dr Shiu has 4 years experience in discrete element numerical simulation. His main research topics concern the non-linear behaviour of the cohesive material (concrete compaction process) and the local damage prediction (perforation, penetration and scabbing) of a structure during a dynamic loading (missile impact). He is currently working on a European project (ProchePuits) for which a PFC2D simulation is involved.
