Contact Information Physics Department NC State University Box 8202 Raleigh, NC 27695 Work Address: Riddick Hall, Suite 421 Phone: (919) 515-2522 Fax: (919) 515-6538 Biography After obtaining his bachelor of arts degree at Beloit College in 1968, Michael Paesler earned his MS (in 1970) and his PhD (in 1975) at the University of Chicago. Following one year as a Guest Scientist at the Max-Planck-Institut für Feskörperforschung in Stuttgart, Germany, he was a post-doc at Harvard University through 1979. Thereafter, he became an Assistant Professor (1980), an Associate Professor (1985) and a full Professor (1990) in the Physics Department at NC State. From 1997 to 2005, Professor Paesler served as the departments Director of Graduate Programs. From 2005 to the present he has been Head of the department. While at NC State, Professor Paesler has taken leave to serve as a Guest Professor at Phillips Universität, Marburg, Germany (1986); Université de Franche Comté, Besanēon, France (1995); Technische Universität, Dresden, Germany (1997); and the Hahn-Meitner Institut, Berlin (1997). Professor Paesler is a Fellow of the Americam Physical Society, and is a member of Phi Beta Kappa, Sigma Xi, and the NC State Academy of Outstanding Teachers. He was the sponsor of the thesis research leading to the American Physical Society Apker Award of Charles Brabec (1990).

Areas of Interest Professor Paesler is focussed research involves the study of condensed matter using synchrotron radiation. Exploiting Extended X-ray Absorption Fine Structure (or EXAFS) he studies local atomic structural changes associated with crystalline/amorphous transitions. Recent studies have centered on Ge2Sb2Te5, a material that has current technological applications and hold promise for future use in reconfigurable interconnects as well as possible expanded use in information storage and processing. EXAFS investigations are undertaken at the Advanced Photon Source located at Argonne National Laboratory. Data analysis is undertaken on the NC State campus.
