About my research: My main research topics are planetary nebulae and their central stars. In particular, those planetary nebulae with hot subdwarf stars in their nuclei. These objects, although scarce, are important to study the origin and evolutionary stage of hot subdwarf stars. I am also interested in the analysis and spectral classification of central stars. Just a small percentage of them have available spectroscopic information, which is needed to study their evolution and to obtain information about their progenitor stars. Finally, I also investigate the role of binarity in central stars of planetary nebulae, which is key to understand the complex morphologies present in planetary nebulae.
