Hi! I'm Waqas Bhatti, an associate research scholar in the Department of Astrophysical Sciences at Princeton University. I work with Prof. Gaspar Bakos' group on the HATNet, HATSouth, and the upcoming HATPI exoplanet transit survey projects.
Current work at Princeton
Most of my focus is on project operations. I built a real-time monitoring and control interface for our robotic telescopes, manage our fleet of data-reduction servers, and maintain our websites. On a more scientific note, I support HATNet exoplanet searches with follow-up photometry of candidate targets, look for variable stars in the HATNet and HATSouth surveys, and contribute to the development of a data-reduction pipeline for the upcoming HATPI survey.
The work I'm most excited about at the moment is building an interactive data exploration portal for the light curves from the HATNet and HATSouth surveys. A preliminary version of the envisioned public interface is now online, lacking several features that still need to be rolled in from an older prototype implementation I built a couple of years ago. An initial public release for the complete data portal is planned to be released soon.
PhD thesis work at JHU
My thesis research was on the identification and characterization of variable point sources found in a large set of time-series photometry data from the Sloan Digital Sky Survey. My collaborators included my thesis advisor, Prof. Holland Ford at Johns Hopkins University, Dr. Larry Petro at the Space Telescope Science Institute, and Prof. Michael Richmond at the Rochester Institute of Technology. Several papers, posters, and presentations related to this work can be found in the articles section. See the data release notes for instructions on how to download and use the raw data, along with some associated results and catalogs. More details are available in my PhD thesis [PDF].
