Almost all my scientific research is done on accreting X-ray binaries,
especially accreting X-ray pulsars. My specialty is the study of the
so-called cyclotron lines found in the spectra of many X-ray pulsars
as an effect of their huge magnetic fields and which can yield 
information on physical conditions in the emission regions. These 
studies involve
mainly observations with RXTE and INTEGRAL. In addition, I am interested
in the high mass stars accompanying the X-ray pulsars, i.e. in the physics
of Be stars and the strong stellar winds of supergiant stars. For the latter,
we have just had a very nice XMM observation of the X-ray pulaar Vela X-1
coming out of its regular eclipse.
