CV

Profile: General goals of research for Professor Glaser and his group are the development of novel theory and experimental techniques in nuclear magnetic resonance (NMR) spectroscopy, with applications to structural studies of biopolymers as well as quantum computing.


NMR is the most powerful method to study molecules in solution. The development of new techniques makes it possible to significantly increase the resolution and sensitivity of crucial NMR experiments, in particular for applications to biological macro molecules such as proteins or nucleic acids. Furthermore, NMR is an ideal test ground for the development and experimental demonstration of fundamental concepts in the emerging techniques of quantum information processing and the control of quantum phenomena in general.
