Bjorn MYSEN is 2025 IMA medalist.

Bjorn Mysen is a Staff Scientist Emeritus of the Carnegie Institution in Washington (USA).

Dr. Mysen is a preeminent figure in experimental petrology and geochemistry whose pioneering research has fundamentally transformed our understanding of silicate melts and magmatic processes. His seminal work elucidated the critical role of volatiles and melt structure in Earth’s interior, and he introduced influential conceptual frameworks – most notably, the control of melt structure on element partitioning – that have become cornerstones of the field. He has authored landmark publications and books, and developed experimental techniques that remain widely adopted today. His groundbreaking studies combined experimental petrology and in situ spectroscopy, and have yielded profound insights into the behavior of geological materials under extreme conditions. Beyond his scientific achievements, he has been a dedicated mentor and editor, fostering international collaboration and contributing significantly to the advancement and vitality of mineralogical sciences.
