Prof Sunney Xie takes Zukunftspreis prize for bio imaging work
May 23, 2008 -- Professor Xiaoliang Sunney Xie, a "founding father" of single-molecule biophysical chemistry -- specifically single-molecule enzymology -- has been selected to receive the Berthold Leibinger Zukunftspreis prize for outstanding research in applied laser technology and valuable contributions to high-resolution optical imaging techniques. The prize will be presented to Xie by jury member Professor Theodor Hänsch at an award ceremony in Ditzingen, Germany on September 15, 2008.
Worth 20,000 euro, Xie is only the second person to receive the prize. The first recipient was Professor Jeffrey H. Kimble of Caltech, in 2006, for his work on Cavity Quantum Electrodynamics.
Sunney Xie, Professor of Chemistry at Harvard University, is well known for his development work on CARS (coherent anti-Stokes Raman Scattering) microscopy. In fact, Xie recently presented a webcast with BioOptics World called State of the Art in CARS Microscopy - Technologies & Applications. Because of his relentless efforts, CARS microscopy has become one of the most important developments in light microscopy. Xie not only first recognized the full potential of CARS in biological imaging, but eliminated most of its technical challenges as well. Unlike fluorescence microscopy, CARS can be used when the observed material cannot be tagged with or is intolerant of fluorescent markers. Xie's team has demonstrated the use of CARS microscopy to identify tumors and monitor metabolism.
A recent success of the Xie group at Harvard's Department of Chemistry and Chemical Biology is a real-time molecule-by-molecule movie of protein production in live cells. The direct observation of single fluorescent molecules in single cells is of great importance in probing gene expression. This generation of proteins according to the genetic codes in DNA is a core process of live regulation in cells. A better understanding of this process will enable scientists to develop new strategies to fight against many diseases.
Born in Beijing, China, Professor Xie earned his doctorate in chemistry at the University of California at San Diego in 1990. After postdoctoral fellowship and Chief Scientist positions at the University of Chicago and the Pacific Northwest National Laboratory respectively, he became Professor of Chemistry at Harvard University in 1999. Xie has been decorated with prestigious awards and prizes, among them the NIH Director's Pioneer Award in 2004 and the Willis E. Lamb Award for Laser Sciences and Quantum Optics in 2007.
The Berthold Leibinger Zukunftspreis is an international research prize awarded biennially by the German non-profit foundation Berthold Leibinger Stiftung. Together with the Berthold Leibinger Innovationspreis awarded biennially since the year 2000, these prizes support research and innovations on laser sources and the applications of laser light. An international jury of laser experts, medical doctors and former business executives selects the prize winners.
