* I am working on unusual products of stellar evolution, stellar variability, young stellar objects and planet formation. We are using Gaia, WISE and TESS data, as well as pursuing theoretical ideas.
* In this context, I am interested in multi-wavelength surveys and data mining and in teasing out rare objects from large datasets, and in physical modeling of these objects.
* I am also continuing my previous projects in observational extragalactic astronomy, on topics that can be broadly summarized as evolution of massive galaxies and their supermassive black holes.
* Specifically, my group, my collaborators and I have studied Active Galactic Nuclei at all wavelengths and all redshifts. We were among the first to discover and characterize galactic winds powered by accretion onto black holes -- an important phenomenon that shaped the cosmic evolution of massive galaxies.
* I maintain active interest in observational and theoretical astrophysics across a wide range of topics.
* Some of our ongoing research projects are listed here, and more are available for interested graduate and undergraduate students (feel free to contact me; email is best).
is presented here, and I didn't have to lift a finger to make that happen, so I gratefully acknowledge the work of the AcademicTree folks, and I greatly enjoyed learning about my tree.
