Principle Investigator

Prof. Andrej Singer – asinger@cornell.edu 

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.

Yifei Sun – ys876@cornell.edu

Stephanie Matson – sdm248@cornell.edu

Stephanie was recently accepted into the Master’s of Science program in Cornell’s Materials Science Engineering department, with an anticipated graduation of Fall ’21. A former treasurer for Cornell’s Materials Society, she helped to organize two trips to the MRS conference, and took one trip to Argonne National labs with the Singer lab, to help with experiments. She joined Singer lab in Fall ’19 for her senior thesis, which was done by tracking center of mass and peak width changes of sodium-ion batteries charged in operando, and she used 3D synchrotron x-rays to measure distortion in the cathode’s crystal lattice.
