Phononic and Electronic Excitations in Complex Oxides Studied with Advanced Infrared and Raman Spectroscopy Techniques

Fryderyk Lyzwa was born in 1990 in Goettingen, Germany. He went to High school in Germany, France and the USA. His Bachelor and Master in physics he performed at the Universita di Bologna, Italy and at the Georg-August University of Goettingen under the supervision of Prof. Dr. Vasily Moshnyaga, where he finished with distinction. For his PhD he joined the group of Prof. Dr. Christian Bernhard at the Universite de Fribourg, Switzerland. During this time, Fryderyk Lyzwa conducted research at the Physics Department in Fribourg, the High-Magnetic field Laboratory (LNCMI) in Grenoble, France and the Max Planck Institute for Solid State Research in Stuttgart, Germany on complex oxide systems with optical spectroscopy techniques. Afterwards, he was a visiting scientist at the Max Planck Institute for Solid State Research in the Department of Prof. Dr. Bernhard Keimer. Since then, he has continued to research as a postdoctoral scientist at the National Synchrotron Light Source II, Brookhaven National Laboratories in New York, USA.
