About Me

I have recently defended my Ph.D. thesis, entitled "Microstructural changes and microbial diversity associated to silicate weathering - Influence on dissolution kinetics from the laboratory to the field". This work was supervised by Dr. Gwenaël Imfeld and Dr. Damien Daval at the University of Strasbourg. I am currently working as post-doctoral researcher on a project funded by BASF Company that aims at deciphering the mechanisms underlying the early dissolution of cement phases.

My main research interest is the reactivity of natural materials, and I have targeted my academic career accordingly: completing four years of training at École Normale Supérieure de Paris to obtain B.Sc. and M.Sc. degrees in Chemistry from Université Pierre et Marie Curie and an M.Sc. in Earth Sciences from Université Paris Diderot.

Introduction to thermodynamics

B.Sc. level

I took part in this introductory thermodynamics course—targeted towards Earth Science students—as a seminar teacher. Through a series of exercises and practical classes, I introduced students to key concepts of classical thermodynamics such as state functions, 1st, 2nd and 3rd laws, chemical potential and chemical transformations.

Course: Earth Sciences, 2nd year

Coordinator: T. Weber

Total: 26 hours

Magnetic survey

B.Sc. level

I took charge of a practical workshop designed to introduce students to geophysical surveying. Specifically, I covered the practical aspects of magnetic data acquisition and treatment.

Matlab Programming

B.Sc. level

Series of seminars and tutorials to familiarize students with programming. Students were introduced to key concepts (variables, operators, loops, functions, etc.) and to the main Matlab features dealing with scientific calculation, graphical outputs and Monte Carlo methods.

Course: Earth Sciences, 3rd year

Coordinator: A. Maggy

Total: 26 hours

Skills

Within the wide field of Biogeochemistry.

Mineralogy

I am using analytical tools in order to track textural and structural transformations occuring in the solid phase.

Geochemistry

Methodologies that I am using to predict, perform and control chemical transformations of minerals.

Microbiology

I have been trained in a series of techniques to investigate microbial diversity associated with mineral weathering processes.

Digital

Even in experimental science, a couple of digital skills are unavoidable.
