Reference excerpt

Patrick Cordier (born February 1, 1961) is a mineralogist who uses experimental and numerical approaches to study the plasticity of geological materials. He has authored or co-authored over 200 articles in international scientific journals. He received the Dana Medal from the Mineralogical Society of America in 2016, and is currently a chief editor of the European Journal of Mineralogy. and a member ofInstitut Universitaire de France.

Education Cordier obtained a master's degree in materials science in 1985 from the School of Engineers of Lille (EUDIL), and a DEA from the University of Lille 1 in materials science. He completed a doctoral thesis on the plasticity of quartz, directed by Professor Jean-Claude Doukhan, at the University of Lille 1 in 1989.

Early career In 1989, Cordier worked as post-doctoral scientist with Professor Arthur Heuer (Department of Materials Science and Engineering, Case School of Engineering, Cleveland, USA). The same year, he joined the University of Lille 1 as an assistant professor. He passed his habilitation to lead scientific research in 1995 at Lille, and became an associate professor of physics in 1996. At the 'Unité Materiaux Transformations' research institute of the University of Lille, he led the research group for Mineral Physics from 1999 to 2017, and the research group for Plasticity from 2017 to 2020.

Current research Cordier is a specialist in transmission electron microscopy and has devoted himself particularly to the study of crystal defects such as dislocations and the plasticity of minerals. In particular, he studies the plasticity of the high-pressure mineral phases of the Earth's mantle. With Philippe Carrez, he is currently developing an approach to this problem based on multi-scale numerical modelling. He has regularly visited at the Bayerisches Geoinstitut (Bayreuth, Germany) at the University of Bayreuth since 1998 to carry out deformation experiments at very high pressures and is presently a visiting professor at the Institute of Mechanics, Materials and Civil Engineering of the Université Catholique de Louvain, Belgium.

Honors Cordier has received French recognition for distinguished service in education (Ordre des Palmes Académiques, Chevalier in 2008; Officier in 2013), and the Grand Prix Frédéric Kuhlmann of the Société des Sciences, de l’Agriculture et des Arts de Lille (SSAAL) in 2015. He has also been a fellow of the Mineralogical Society of America since 2008 and received the Dana Medal from them in 2016. In 2019, he became the first French fellow of the American Geophysical Union in the focus group 'Mineral and Rock Physics'. The same year he was elected at Institut Universitaire de France as a senior member. He is the current president (2018–2020) of the International Mineralogical Association (IMA). He has also served as the first vice-president (2016–2018) of the IMA, and the vice-president (2004–2007) and president (2008–2009) of the French Mineralogical Society (Société Française de Minéralogie et Cristallographie). He has twice received ERC-Adv grants, for the projects RheoMan (2011–2017) and TimeMan (2018–2022). In 2022, he was elected a member of the Academia Europaea.

Worked examples

Example 1 — a first encounter with Patrick Cordier (mineralogist)

Start with the simplest possible case. Write down what Patrick Cordier (mineralogist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Patrick Cordier (mineralogist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Patrick Cordier (mineralogist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Patrick Cordier (mineralogist)

In research: Patrick Cordier (mineralogist) appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Patrick Cordier (mineralogist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Patrick Cordier (mineralogist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Academic staff of the Lille University of Science and Technology, Chevaliers of the Ordre des Palmes Académiques, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick Cordier (mineralogist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
