Research Interests

Dr. Rath's research interests involve the use of single crystal X-ray diffraction techniques for three dimensional solid state-molecular and crystal structure determination of novel organic and organometallic compounds. Currently, Dr. Rath is the Director of the X-ray Diffraction Laboratory of the Department of Chemistry and Biochemistry and the Center for Nanoscience. Current research interests include study of weak interactions in the solid state, polymorphism, structure solution and refinement of twin structures and development of techniques and instrumentation for accurate data collection for small molecules.
