The ability to shape materials on length scales as small as a billionth of a metre (the nanoscale) is opening new frontiers in science and technology. Dr. Ramunno's research is key to understanding how powerful lasers can be used to make delicate and precise "cuts" and other restructuring in materials in order to make microscopic devices that will lead to advances in areas such as information and communications technology and medicine. Her laboratory is a high-performance computer with which she uses to accurately simulate the effect of intense lasers on materials. While her longer term goal includes bulk transparent materials such as glass, she is working towards this goal by studying the effect of lasers on more exotic materials such as tiny clusters of condensed noble gas atoms. Since the latter have many properties similar to transparent materials -- but are much smaller and hence easier to simulate -- studying clusters will provide a critical stepping stone to understanding how lasers can restructure bulk solids. Dr. Ramunno's program includes expanding upon her current computer codes to handle systems of larger and larger sizes, in order to simulate material restructuring in devices for the first time.

在小至十亿分之一米（纳米级）的长度尺度上塑造材料的能力正在开辟科学和技术的新领域。 Ramunno 博士的研究对于了解如何使用强大的激光对材料进行精细且精确的“切割”和其他重组以制造微型设备至关重要，从而推动信息和通信技术以及医学等领域的进步。她的实验室是一台高性能计算机，她用它来精确模拟强激光对材料的影响。虽然她的长期目标包括玻璃等大块透明材料，但她正在通过研究激光对更奇特的材料（例如凝聚的惰性气体原子的微小簇）的影响来实现这一目标。由于后者具有许多与透明材料相似的特性——但更小，因此更容易模拟——研究簇将为理解激光如何重组块状固体提供关键的垫脚石。 Ramunno 博士的项目包括扩展她当前的计算机代码以处理越来越大尺寸的系统，以便首次模拟设备中的材料重组。
