Michael Stöger-Pollach was born in Vienna in 1974. After school he started to study physics at the Vienna University of Technology in 1992. During his studies he collected experience at the Friedrich-Schiller Universität Jena, Germany, the Humboldt Universität zu Berlin, Germany, and the École Central Paris, France. He finished his studies in 1999 with his diploma thesis on mircocrystalline solar cells. After military service he came back to the former Institute for Applied and Technical Physics (now: Institute for Solid State Physics) as a PhD student where his main research interests are on separation of oxygen influenced and uninfluenced ELNES

In 2002 he worked at the National Research Centre for High Resolution Electron Microscopy of the Netherlands at the Delft University of Technology where he had the chance to use a world wide unique TEM with pre- and post-specimen energy filters. This provides world's best energy resolution in electron energy loss spectrometry. Research topics were - based on his former experiences - the separation of ELNESes at interfaces and grain boundaries and direct measurements of silicon and metal-induced gap states (MIGS) at Schottky barriers. After finnishing his theses he became a member of USTEM staff. Since October 2004 he also works on valence EELS on nanometer scales. This field of research is of great importance in semiconductor industry, because many problems appear when reducing dimensions of integrated circuits. Main topics within valence EELS are: quantum size effects, Cerenkov radiation, gap states (defect states, interface states, surface states), delocalization of energy losses at interfaces and surfaces.

From summer 2006 to autumn 2007 he was also engaged in the CHIRALTEM project about magnetic circular dicroism, where he could improve the spatial resolution by 100 times within one year. 

Since 2007 he is University Assistent at the University Service Center for TEM. 

Since 2009 he started his research in EELS at low beam energies. By avoiding relativistic energy losses he is now able to accurately study the dielectric behaviour of nearly all materials. The energy resolution of the TECNAI G20 was improved to 0.25 eV at 20 keV beam energy, which is nearly the value of a monochromated electron source. In the meantime he tuned the TEM and GIF vor "high tensions" of only 6 kV.

2011 he was elected a Member of The Institute of Physics (MInstP).

He did his habilitation in june 2012.

His recent research activities are focussed onto optical excitations in transmission electron microscopy being experimentally observed by employing the newly installed cathodoluminescence system.

He is married and has two children. Besides his scientific interests he acted as a scout master in the Scout group 11 "St. Severin" of the Austrian Scout Association untill June 2004.
