**About the Editor**

#### **Georg Junker**

Georg Junker received his Ph.D. degree from Wurzburg University (Germany) in 1989; ¨ subsequently, he assumed an assistant position at the University of Erlangen-Nurnberg (Germany), ¨ where he also received his Habilitation and became a Privatdozent. He acts as referee and advisory board member for several scientific journals and has authored more than 60 publication, including two books. He is currently affiliated with the European Southern Observatory in Garching (Germany) and the Institute for Theoretical Physics at the University of Erlangen-Nurnberg (Germany). ¨

His research activities focus on all kinds of symmetry aspects of physical systems. He has made major contributions within Feynman's path-integral approach to quantum mechanics, and has also successfully applied group theoretical methods to problems in quantum chaos and statistical physics. His current research interest is on supersymmetric quantum mechanics and its application to quantum mechanics and statistical and solid-state physics.
