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.

Kirsten Hall, graduate student 2014 - present, quasars and large-scale structure in CMB data (joint project with T. Marriage) [Winner of the Best Student Speaker award, Penn State neighborhood cosmology meeting, April 2016; winner of the NRAO student observing support fellowship, Fall 2018; selected participant in the 2019 Lindau Meeting], our paper on downsizing and our paper on the SZ effect
Hsiang-Chih Hwang, graduate student, 2016 - present, our paper on radio emission in radio-quiet quasars, our papers on sual supermassive black hole candidates and our paper on short-period binary stars; currently working on stellar variability and emerging Galactic surveys [Gardner Fellow, Spring - Summer 2018]
Carlos Anicetti, first year graduate student, 2019 - present, morphological analysis of quasar host galaxies
Yuzo Ishikawa, first year graduate student, 2019 - present, optical and X-ray spectral analysis of quasars with winds
Vedant Chandra, undergraduate student, 2018 - present, modeling of white dwarf atmospheres [recepient of the 2019 Dean's Undergraduate Research Award] (co-advising with Hsiang-Chih Hwang)
Evan Petrosky, undergraduate student, 2019 - present, quantifying stellar variability (co-advising with Hsiang-Chih Hwang)

I am collaborating with (and have papers with) CAS postdocs David Nataf and Caroline Huang. Previously I collaborated with CAS postdocs Kate Rowlands [now faculty at STScI], 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.

Research interests:

* 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).

My academic tree:

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.
