Dr. Kirian works primarily in the field of x-ray free-electron laser science. His work centers on the development of experimental measurement and diffraction analysis techniques for static and time-resolved studies of biological macromolecules. Three primary techniques that are under development are femtosecond serial crystallography, time-resolved solution scattering, and single-molecule imaging. Among other things, Dr. Kirian develops particle injection systems for placing biomolecules at the intense focus of free-electron lasers, and he develops new techniques for lensless diffractive imaging. Prior to joining ASU Physics as an assistant professor, Dr. Kirian received his PhD in physics at ASU in 2011 and worked as a postdoc at the Center for Free-Electron Lasers in Hamburg from 2011-2014.
