* Announcement of a short course* We are pleased to announce a short course on Introduction to *Phase Field Modeling and Applications in the Earth Sciences*, to be held at */ICAMS, Ruhr Universität Bochum, Germany/*, from *February 2 - 7, 2025*. This course is part of Research Unit (FOR 2881), managed by the Universities of Bochum and Hannover. The course will be taught by Prof. Ingo Steinbach, a pioneer in Phase Field methods, and his team in Bochum. Bochum is centrally located in Europe, making it easily accessible by road, train, and air (Düsseldorf and Dortmund are the nearest airports; Frankfurt is a two-hour train ride away, and Cologne-Bonn is even closer). The surrounding region, including Cologne and Düsseldorf, is densely populated and boasts a world-renowned cultural infrastructure. *Course Content:*The course is designed for Earth scientists interested in applying quantitative methods to understand Earth materials and processes, particularly compositional and textural evolution. While the Phase Field method has broad applications, the focus of research in Bochum and Hannover is on retrieving information on process timescales from compositional zoning and textural data (e.g., crystal size distribution). An example of such application may be found in Kundin et al. (2023), https://doi.org/10.1029/2023JB026718. *Goals and Expected Profile of Participants:*This course targets graduate students and early career scientists with a background in thermodynamics/kinetics, quantitative methods, and coding. Researchers in Geophysics, Geochemistry, and Petrology will likely benefit from the course. In addition to lectures, the course will include hands-on training to enable participants to conduct their own modeling. All instruction and exercises will be in English. To ensure a hands-on experience, we will limit the number of participants to around 15, on a first-come, first-served basis. Interested participants can express their intention to register by sending an email with a statement describing their background and reasons for wanting to participate to: Diffchron@rub.de <mailto:Diffchron@rub.de>. Please include your experience with quantitative methods and modeling to help us evaluate your application. *Registration and Fees:*There are no course fees. Upon receiving an acknowledgment that a place is available, you will receive further information for official registration. Further Information: More details on course content, travel, accommodation, and other updates will be provided later on a short course webpage. The webpage address will be sent to registered attendees once it is set up.
