摘要

能够获得达纳奖章,我深感荣幸和惭愧。首先,我要感谢我的提名人和支持信的作者、MSA 理事会以及委员会推选我获得这一殊荣。我今天走到这里的道路是漫长而曲折的。我的同事和朋友很少有人知道,我的职业生涯从一开始就与众不同。在我的家乡布拉索夫,位于特兰西瓦尼亚的喀尔巴阡山脉中段,我以某种方式开始了电气工程的本科课程。我学的是数学、物理和计算机。但学了不到两年,我就觉得这不适合我,于是我放弃了,离家出走,追随我真正的爱好--古生物学。我搬到了布加勒斯特,开始在布加勒斯特大学地质学和地球物理学系读本科。很快,对方程和数理逻辑的需求再次敲响了我的大门。在这里,我非常幸运地在第一学期上了一堂晶体学课,授课老师是 Gyury Ilinca。我要衷心感谢他,因为是他把我带入了对称性的奇妙世界,在这里,我终于可以应用我所知道的所有数学知识、群论和矩阵,去做一些有用而美好的事情。在布加勒斯特大学的四年里,我成为了一名真正的矿物学家。在本科学习的第二年,我就开始从事研究工作。为了弥补分析工具的不足,我做了大量的理论和计算工作。我编写了几个小型软件包,撰写了第一篇科学论文,并尽可能多地阅读。我热衷于阅读《美国矿物学家》,对我来说,达纳就是矿物学的缩影。于是,我接受了一份工业合同博士奖学金,前往比利时。我在卢万天主教大学担任助教,从事芬兰北部索克里碳酸盐岩铌矿床的研究工作。但在我到校一年后,该大学的地质系就关闭了。我决定放弃铌矿研究,并在我的博士生导师菲利普-索内(Philippe Sonnet)(我要感谢他的坦诚和理解)的支持下,向材料科学领域的泽维尔-贡兹(Xavier Gonze)提出了申请。我想研究相变和非同调结构的起源。我非常感谢泽维尔接受我加入他的研究小组,并提出了自己的研究课题。在接下来的五年里,ab initio 模拟成了我的世界,abinit 小组也成了我的家。由于我不知道从哪里开始,我有机会与克雷格-比纳(Craig Bina)和杰伊-巴斯(Jay Bass)通过电子邮件进行了一系列讨论。作为博士后,我漂洋过海,在明尼阿波利斯度过了第一个冬天,与雷娜塔-温茨科维奇(Renata Wentzcovitch)一起研究下地幔,我要感谢她给了我很多建议,并向我介绍了分子动力学。我首先要感谢罗恩-科恩(Ron Cohen)对我的指导,他教了我很多物理知识,随着时间的推移,他还成了我的朋友,然后是鲁斯和戴夫、费和斯蒂尔利,以及地球物理实验室和 DTM 的所有其他工作人员。他们对科学的洞察力始终是我灵感的源泉。在卡内基之后,我在拜罗伊特担任洪堡研究员,继续在计算机上探索地球的深度。卡内基和拜罗伊特都是很好的地方,我要感谢那些年所有的同事和朋友,是他们帮助我提高了作为一名科学家和一个人的素质。博士后阶段即将结束时,我很幸运地在第一时间获得了国家科学研究中心的职位。我必须承认,在拜罗伊特之后搬到里昂是一个相当大的文化冲击。不过,我觉得自己挺过来了,变得更像法国人了。由于我喜欢变化,两年前,我又搬到了巴黎的 IPGP,但还是在同一个 CNRS。在法国国家科学研究中心的这些年里,我的科学从晶体学发展到光谱学,从固体发展到熔体,如今又从深层发展到早期地表。不知何故,我最终做的事情与我逃离的事情如出一辙:数学、物理和计算机。最后,我要感谢我的家人,感谢一直支持我的父母,感谢我的女儿萨拉和我的伴侣塞西尔,感谢他们这么好的人,当我有时迷失在希尔伯特空间中试图解开一些奇怪的波函数时,他们都能容忍我。

Acceptance of the Dana Medal of the Mineralogical Society of America for 2023
I am deeply honored and humbled to receive the Dana medal. I would like to start by thanking my nominee and writers of support letters, the MSA council, and the committee for selecting me for this prestigious award. My path to here, today, was a long and tortuous one. Few of my colleagues and friends know that I started a very different career at the very beginning. I somehow began undergraduate classes in electrical engineering in my hometown, Brasov, in Transylvania, in the middle of the Carpathians. I was doing math, physics, and computers. But after less than two years, I decided this was not for me, so I quit, ran away, and followed my real passion, paleontology. I moved to Bucharest and started as an undergraduate in the Faculty of Geology and Geophysics at the University of Bucharest. Very soon, the need for equations and mathematical logic knocked again at the door. Here I was extremely fortunate to have in the first semester a class on crystallography, taught by Gyury Ilinca. I would like to warmly thank him, for he is the one who introduced me to the wonders of symmetry, where I could finally apply all the math I knew, the group theory, the matrices, to do something useful and beautiful.

期刊介绍: American Mineralogist: Journal of Earth and Planetary Materials (Am Min), is the flagship journal of the Mineralogical Society of America (MSA), continuously published since 1916. Am Min is home to some of the most important advances in the Earth Sciences. Our mission is a continuance of this heritage: to provide readers with reports on original scientific research, both fundamental and applied, with far reaching implications and far ranging appeal. Topics of interest cover all aspects of planetary evolution, and biological and atmospheric processes mediated by solid-state phenomena. These include, but are not limited to, mineralogy and crystallography, high- and low-temperature geochemistry, petrology, geofluids, bio-geochemistry, bio-mineralogy, synthetic materials of relevance to the Earth and planetary sciences, and breakthroughs in analytical methods of any of the aforementioned.
