You happen to have come across the homepage of Nadia L. Zakamska.
Where I am now:
I am an associate professor of astrophysics in the Department of Physics and Astronomy at Johns Hopkins University. I have been the chair of the graduate program committee (= director of graduate studies) for the Department of Physics and Astronomy since Jan 2018.
Before I came to JHU in 2011, I was a research associate at Kavli Institute for Particle Astrophysics and Cosmology at SLAC/Stanford University and a five-year member at the Institute for Advanced Study. I got my Ph. D. in Astrophysics from Princeton University in 2005.

I am collaborating with (and have papers with) CAS postdocs David Nataf and Kate Rowlands. Previously I collaborated with CAS postdocs Jorge Barrera-Ballesteros [now faculty in Mexico] and Guangtun Zhu [now in finance]. I am a co-director of JHU CARE, the Center for Astrophysics Research Experience program for undergraduates.

Undergraduate students (if over two semesters or common papers):
* I am excited to be starting new projects on unusual products of stellar evolution, stellar variability, young stellar objects and planet formation. We are using Gaia and WISE 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.
* Most (though not all) of my publications in the last 7 years have been 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 (here you can find a popular article about black holes, Active Galactic Nuclei and their luminous subclass - quasars). 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.
