Scientific Interests and Work

Physical and chemical properties of energetic and related materials under static and dynamic loading.

Dr. Dreger’s research interests are aimed at further understanding the physical and chemical changes in molecular solids under extreme conditions of high pressure and temperature. His work uses various laser spectroscopies (linear, nonlinear, time resolved) and synchrotron x-ray diffraction, and emphasizes the molecular scale characterization of pressure effects in molecular systems, including high explosives. Currently, Dr. Dreger is investigating the optical response of energetic crystals and model organic crystals to both static (diamond anvil cell) and shock (gas gun) loading. He has co-authored over 100 scientific publications.

Background

After receiving his doctorate degree, Dr. Dreger was appointed as an Assistant Professor in the Department of Molecular Physics at the Technical University of Gdansk. From 1989 to 1992 he was a visiting post-doctoral fellow at the University of Illinois at Urbana-Champaign (UIUC), working in the high-pressure laboratory of Professor Harry G. Drickamer. Dr. Dreger returned to UIUC in 1994 as a research scientist. He joined the faculty at the Institute for Shock Physics at Washington State University in July 1998.

Education

Ph.D. (Physics), 1986, Technical University of Gdansk (TUG), Gdansk, Poland.
