Research interests

• Stellar astrophysics
• High Energy Astrophysics
• Stellar Populations
• Stellar Dynamics (less of current interest, more of the past)
• Hydrodynamics

• Stellar astrophysics

• Detailed evolution of single and binary stars; internal structure, convection and nucleosynthesis
• Mass transfers events and the star response on the mass loss or the mass accretion
• Magnetic braking
• Evolution of pre-main sequence stars
• Rotationally induced mixing in stars
• Evolution of merger products and post-collisional stars (see also hydrodynamics)
  

• High Energy Astrophysics

• Low-mass X-ray binaries: formation and evolution
• Type Ia Supernovae progenitors
  
• Nature of Ultra-luminous X-ray binaries
• Gamma-ray burst progenitors: formation and rates

• Stellar Populations

• Populations of massive stars
• Populations of (point) X-ray sources in globular clusters and other galaxies
  
• LISA and LIGO sources
• Population synthesis codes for binaries and triples

• Stellar Dynamics

• Binaries and triples and dense stellar systems

• Hydrodynamics

• Common envelope physics
• Slow mergers, including mass transfers and nucleosynthesis   (movies: entropy during a mass transfer from a spiral-in star to the hot and dens core; ; temperature if nucleosynthesis is included)
