Dr. Ryba celebrates 60 years on the faculty of the Materials Science and Engineering Department at The Pennsylvania State University. His dedication to the ICDD X-ray clinics is evident in 37 years of instruction dating back to when the clinics were held at SUNYA. At Penn State, his teaching responsibilities have included powder and single crystal x–ray diffraction, crystallography, characterization of materials, microcomputer usage, general aspects of materials, physical metallurgy, electronic and other physical properties of materials, technical writing, and graduate level courses on advanced geometrical crystallography, the Rietveld method, advanced powder diffraction, and small angle scattering.
He has also taught courses in crystallography and X-ray diffraction at three major universities in China.
Research interests: crystal structures and crystal chemistry of intermetallic compounds and quasicrystals; X-ray diffraction studies of a variety of materials; and new directions in crystallography.
ICDD: various committees and task groups; yearly X-ray diffraction clinics instructor; database editing
