In honor of its two recent National Medal of Science recipients, Jan Achenbach and Tobin Marks, Northwestern University held a National Medal of Science Symposium on May 14.

Achenbach and Marks received their medals at a White House ceremony in July 2007. The medal honors individuals for “pioneering scientific research in a range of fields, including physical, biological, mathematical, social, behavioral and engineering sciences, that enhances our understanding of the world and leads to innovations and technologies that give the United States its global economic edge.”
