Principle Investigator

Prof. Andrej Singer – 

Assistant Professor, David Croll Sesquicentennial Faculty Fellow

Andrej Singer received his Ph.D. (2012) in Physics from the University of Hamburg, Germany in the lab of Prof. Edgar Weckert and Prof. Ivan Vartanyants, following a Physics diploma from the University of Muenster, Germany. He studied the properties of new x-ray sources, particularly their ability to generate interference patterns, similar to lasers in optics. He then worked as a Postdoc in the lab of Prof. Oleg Shpyrko at the University of California, San Diego. Dr Singer’s group uses coherent x-ray scattering techniques at synchrotrons and free-electron lasers to study a wide range of materials, spanning from quantum materials to applied energy materials in operando devices. Dr. Singer is interested in understanding the fundamental properties of energy materials and quantum materials out-of-equilibrium.
