I will review my past and current research, mainly focussed on the interactions between stellar dynamics, hot ISM, AGN feedback, black hole accretion in early...

Gamma Dor stars (M = 1.2-2.5 M⊙; spectral type A-F) are very interesting from an asteroseismic point of view. They show gravity modes, which are the only modes...

NASA's Kepler Satellite was successfully launched into space on 6 March 2009. The goal of this mission is ambitious and exciting. Using Kepler we expect to...

Different components of galaxies are the result of internal and environmental processes during their lifetimes. Disentangling these processes is an important...
