Keynote and invited talks for the workshop.
Keynote
Dr. Katrin Daehn
Massachusetts Institute of Technology (MIT), Cambridge, MA, USA
Talk title
“Copper contamination in the current and future steel system”
Dr. Katrin (Katie) Daehn is a research scientist at the Materials Research Laboratory at MIT. She grew up in Columbus, Ohio, earned her BS in Materials Science and Engineering at The Ohio State University and a PhD in Engineering at the University of Cambridge as a Cambridge Trust scholar, working with Prof. Julian Allwood to study copper contamination in end-of-life steel recycling. She aims to integrate industrial ecology, the study of mass and energy flows at a societal level, with thermodynamic and experimental insights to develop efficient, competitive and sustainable materials processes and practices. Achievements she is particularly proud of include receiving the Goldwater scholarship, authoring the Top Policy paper in Environmental Science and Technology (2017), and working with a team to study and scale-up the extraction of copper and iron from ore using only electricity. She is a third-generation metallurgist and wants to contribute to the development of the next generation of electrified industrial processes using her skills in high-temperature electrochemistry, as well as data visualization, communication and education.
Invited speaker
Pr. Philippe Maugis
Aix Marseille University, CNRS, IM2NP
Talk title
“A thermo-kinetic model of solute segregation at high-angle grain boundaries”
Philippe Maugis is full professor at IM2NP (Institut for Materials, Microelectronics and Nanosciences of Provence – Marseille). He worked for 13 years on the physical metallurgy of steels within the Arcelor research centre, where he gained experience in the field of phase transformations in plain carbon and stainless steels. He specializes in multiscale modeling of microstructural evolutions in steels, from the atomic scale (Density Functional Theory, Kinetic Monte Carlo) to the macroscopic scale (mean-field models).
Invited speaker
Pr. Frédéric Christien
Mines Saint-Étienne, Mines-Télécom, Saint-Étienne, France
Talk title
“Interface Segregation of Solutes in Metals. Experimental Approach.”
Frédéric Christien began his career as a lecturer at the University of Nantes, then joined the École des Mines de Saint-Étienne as a professor in 2015. For 25 years, he has devoted much of his research work to the phenomenon of interfacial segregation in metals. In particular, he has contributed to the development of various measurement methodologies using Auger and X-ray spectroscopies, NanoSIMS and transmission electron microscopy.
Invited speaker
Dr. Manon Rolland
UMET, Université de Lille, Lille, France
Talk title
“Improving scrap recycling: technical, economical, societal and environmental aspects”
Manon Rolland is an assistant-professor at UMET (Unité Matériaux Et Transformations) in Lille. Her primary field of expertise is the modelling of solid-solid phase transformation in metallic materials. More recently, she has started working on several topics related to metallic material recycling: applying the thermodynamic and kinetic based modelling tools to optimize the presence of tramp elements or to purify alloys, as well as investigating and optimizing matter and scrap flows throughout the steel sector.
Invited speaker
Dr. Philippe Russo
ArcelorMittal, Maizières-lès-Metz, France
Talk title
“Challenge of Residual elements in Steel Recycling”
Philippe Russo is a Research engineer working for ArcelorMittal in Maizières lès Metz, graduating in 1986 with a specialization in Mineral Processing. That same year, he joined IRSID to work on the iron ore sintering process. He then expanded his expertise to include ferrous scrap preparation, notably by taking on the role of Technical Director at CTRA (Technical Center for Steel Recycling), which led him to improve ferrous scrap shredding and sorting processes. Subsequently, he was head of the Raw Materials cluster within IRSID's, and then Technical Advisor, responsible for R&D projects focused on improving ferrous scrap quality and recycling steel produced by the ArcelorMittal Group. Philippe Russo has participated in numerous European research projects and is the author or co-author of many publications on ferrous scrap preparation and steel recycling. He also teaches steel recycling at various engineering schools and universities.

To be announced
Invited speaker
Dr. Nicolas Grundy
Thermo-Calc Software AB, Stockholm, Sweden
Talk title
“Thermodynamic Approaches to Managing Impurities in Steel Production”
Nicholas Grundy completed his Ph.D. at ETH Zurich, where he focused on CALPHAD-based thermodynamic assessments and model development for oxide systems used for functional ceramics. He then undertook a postdoctoral fellowship at École Polytechnique in Montréal, working within the FactSage group on thermophysical properties and database development of slag systems. Following his academic work, Nicholas spent ten years in industry as a process metallurgist with SMS group. He joined Thermo-Calc Software AB in 2017, where his primary focus has been advancing the application of Thermo-Calc to ferrous process metallurgy.
