Emmanuel Candes, a mathematician at the California Institute of Technology, has been selected to receive the National Science Board's prestigious Alan T. Waterman Award. The board cited Candes' development of new mathematical tools that allow efficient digital representation of wave signals, together with his discovery of new methods to translate analog data into a cleaner, tighter digital form--work that promises to improve the digital processing of signals in a vast array of modern technologies.With the advent of digital technologies, translating analog information faithfully into digital representations has been a major challenge. The translating method, called sampling, must select enough information from the analog object to adequately reproduce it in digital form. Otherwise, key information may be lost.Recently, Candes developed a new sampling mechanism that allows the faithful recovery of signals and images from far fewer data bits than traditional methods use. This new sampling theory may come to underlie protocols that sample and compress data simultaneously and much faster. "In practice," Candes said, "this means one could obtain super-resolved signals from just a few sensors."The annual Waterman award recognizes an outstanding young researcher in any field of science or engineering supported by the National Science Foundation (NSF). Candidates may not be more than 35 years old, or seven years beyond receiving a doctorate. In addition to a medal, the awardee receives a grant of $500,000 over a 3-year period for scientific research or advanced study in the mathematical, physical, medical, biological, engineering, social, or other sciences at the institution of the recipient's choice.

加州理工学院数学家伊曼纽尔·坎迪斯（Emmanuel Candes）被选为美国国家科学委员会著名的艾伦·t·沃特曼奖得主。委员会提到了Candes开发的新的数学工具，这些工具可以有效地以数字形式表示波浪信号，同时他还发现了将模拟数据转换为更清晰、更紧凑的数字形式的新方法，这些工作有望改善大量现代技术中信号的数字处理。随着数字技术的出现，将模拟信息忠实地转换为数字表示已成为一个重大挑战。翻译方法，称为采样，必须从模拟对象中选择足够的信息，以充分再现其数字形式。否则可能导致关键信息丢失。最近，Candes开发了一种新的采样机制，可以从比传统方法使用的更少的数据位中忠实地恢复信号和图像。这种新的采样理论可能成为同时更快地采样和压缩数据的协议的基础。“在实践中，”坎迪斯说，“这意味着人们可以从几个传感器中获得超分辨率信号。”一年一度的沃特曼奖旨在表彰由美国国家科学基金会（NSF）资助的科学或工程领域的杰出青年研究人员。申请人年龄不得超过35岁，或获得博士学位后不得超过7年。除奖章外，获奖者还将在3年内获得50万美元的资助，用于在获奖者选择的机构进行数学、物理、医学、生物、工程、社会或其他科学领域的科学研究或高级学习。
