ABOUT CRAIG'S WORK
Craig Fennie is a materials scientist combining the tools of theoretical physics with those of solid-state chemistry to discover new materials with desirable electrical, magnetic, and optical properties. Instead of attempting to manipulate the capabilities of previously existing materials, Fennie identifies completely new materials by employing a “first principles” approach based on quantum mechanics, in which they are rationally built up, atom by atom, to possess the needed physical properties. A central line of his research focuses on understanding and controlling the atomic-scale structural complexity that is key in creating new macroscopic properties. One application of this strategy has been to develop materials with coupled electrical and magnetic states, which opens the possibility of digital data storage being controlled electronically rather than magnetically.

As a theoretician, Fennie predicts the physical properties of candidate compounds and then works closely with experimental physicists to synthesize and test them. He has already correctly predicted ferroelectric and ferromagnetic characteristics of several previously unexplored metal oxides. His theories have indicated, for example, that a europium titanium oxide, when stretched, would exhibit unusually strong coupled electric and magnetic properties; the resulting material could lead to dramatic advances in memory storage capacity.

In addition to structures that may serve as the basis for future electronic devices, Fennie is also developing strategies to design compounds with desirable optical properties that could help improve the efficiency with which materials capture solar energy. Fennie’s theoretical work is not only laying the foundation for the design of materials with the potential to transform electronics and communication technology, but it could also lead to the creation of new structurally and chemically complex materials with capabilities beyond our current understanding and imagination.

BIOGRAPHY
Craig Fennie received B.E.E. (1993) and M.S.E.E. (1996) degrees from Villanova University and a Ph.D. (2006) from Rutgers University. He was a postdoctoral fellow (2006–2008) at Argonne National Laboratory before joining the School of Applied and Engineering Physics at Cornell University, where he is currently an assistant professor. His scientific publications have appeared in Physical Review Letters, Nature, Nature Materials, and Nature Communications, among others.

关于克雷格的工作
克雷格-芬尼是一位材料科学家，他将理论物理学的工具与固态化学的工具相结合，发现具有理想的电、磁和光学特性的新材料。芬尼没有试图操纵以前存在的材料的能力，而是通过采用基于量子力学的 "第一原理 "方法来确定全新的材料，在这种方法中，它们被合理地逐个原子建立起来，以拥有所需的物理特性。他研究的一条中心路线是理解和控制原子尺度的结构复杂性，这是创造新的宏观特性的关键。这一策略的一个应用是开发具有电和磁耦合状态的材料，这为数字数据存储的电子控制而非磁控制提供了可能。

作为一名理论家，芬尼预测了候选化合物的物理特性，然后与实验物理学家密切合作，合成和测试它们。他已经正确地预测了几种以前未曾探索过的金属氧化物的铁电和铁磁特性。例如，他的理论表明，一种铕钛氧化物，当被拉伸时，将表现出异常强烈的电和磁耦合特性；由此产生的材料可能导致存储器存储能力的巨大进步。

除了可能作为未来电子设备基础的结构外，芬尼还在开发设计具有理想光学特性的化合物的策略，这可能有助于提高材料捕获太阳能的效率。芬尼的理论工作不仅为设计有可能改变电子和通信技术的材料奠定了基础，而且还可能导致创造出结构和化学上复杂的新材料，其能力超出我们目前的理解和想象。

个人简历
克雷格-芬尼在维拉诺瓦大学获得电子工程学士学位（1993年）和电子工程硕士学位（1996年），在罗格斯大学获得博士学位（2006年）。在加入康奈尔大学应用与工程物理学院之前，他曾在阿贡国家实验室担任博士后研究员（2006-2008），目前是该学院的助理教授。他的科学论文发表在《物理评论快报》、《自然》、《自然材料》和《自然通讯》等刊物上。
