Research Interests 


  1. Wide-Field surveys (AGNs, Galaxies, CV, White dwarfs and hot subdworfs)

  2. Active Galactic Nuclei and Quasars  (Central Engine and Environment)

  3. Compact Groups of Galaxies

  4. Observational Astronomy

My main area of study is the multiwavelength observations and interpretation of the processes going on around supermassive black holes (BH): the nature of the power source in active galactic nuclei (AGNs); the cosmological evolution of supermassive BH and their host galaxies, and relationships with environment in small and large scales. One of my long-term interests has been variability of the radiation from AGNs to probe what is going on around the supermassive BH (structure and kinematics of the broad/narrow-line emission regions) and power generation.
