I was born and educated in Argentina. Worked at IAFE, Buenos Aires, Argentina. Worked at Munich University Observatory, Germany, 1986-87 (Humboldt Fellowship) and 1991-2001. Working at the IfA since 2002.

My current research interests are: central stars of Galactic planetary nebulae (PNs) and kinematic studies of extragalactic PNs.

Member of IAU Division H (interstellar matter and local universe), Commission H3 (planetary nebulae).
