The IAMG Student Chapter from University of Lorraine, France, is an active student chapter of the International Association for Mathematical Geosciences (IAMG). The IAMG is a scientific association at the frontier of geosciences, mathematics and computer sciences promoting international cooperation in the application and use of mathematics in geological research and technology.

Our Student Chapter, which was founded in 2009, is historically related to the numerical geology research team from Nancy (known as the RING team) and the Nancy School of Geology. It includes MSc and PhD students with backgrounds in geology, reservoir engineering, geophysics and computer sciences who work on the topics of structural and stratigraphic modeling, physical process simulations, uncertainty characterization, meshing strategies, model complexity and scale management, data interpretation and integration, etc. We are looking forward to recruit new members with alternative backgrounds to diversify our spectrum of competences and develop new student collaborations.

Activities

Activities

As an IAMG student chapter, we aim to develop the joint application of mathematics and computer sciences in the domains of geosciences, and especially to students. We organize various activities, both regular and occasional, to promote our research work and IAMG activity.

Lectures

Our principal activity consists in organizing weekly lectures that are given either by Student Chapter members, permanent researchers from the RING team, or visiting colleagues. These lectures are the occasion to present and share our recent research and progress, but also to get feedback and advice from colleagues on our work, and new insights on other research domains. The list of both past and incoming lectures is here. If you are interested in attending a lecture online, you can contact any IAMG Student chapter member to ask for a Microsoft Teams link.

Field trips

By receiving funds from IAMG, we have the opportunity to plan field trips with the aim of establishing a connection between geological features exposed in natural environments and the numerical modeling of the petrophysical properties of these objects, as well as the mathematical methods to describe them or to simulate transfer processes such as fluid flow.

After a break in such events during the Covid period, the student chapter of Nancy is resuming its activities with a first field trip schedulded for October 25, 2023, Aix-en-Provence, France.
