Astronomical Research
My active research is in several areas, including star formation, IR observations of near-earth objects, and near- and mid-infrared observations of planetary nebulae.

Massive Star Formation
Several of my current projects are related to the study of massive star formation in the Cygnus-X region. I led a team that performed a Spitzer Legacy Survey during the cyogenic Spitzer mission, and we performed a survey with Herschel as well as several other investigations of the massive star formation in this region. See some of the images below that resulted from this project.
A related project is called Origin and Evolution of Rich Clusters (performed with Gözde Saral), where we have studied the high mass star forming regions W49, W43, and W51. Another project called Star Formation in the Outer Galaxy (with Elaine Winston and Volker Tolls) explores the differences in star formation activity in the lower density and lower metallicity regions at larger distances from the Galactic Center.
Infrared/X-ray/submm Observations of the Galactic Center Black Hole
Our team is studying the emission mechanisms at work in the Galactic center black hole (Sgr A*) by monitoring the source in up to 24-hour periods in the infrared with Spitzer, X-ray with Chandra, and submm at ALMA and the SMA. See our project web page for details and the current status. A couple press releases are in the table below.
Near Earth Object (NEO) Observations with Spitzer
I am part of a team that is studying NEOs with Spitzer. We can more accurately estimate the object's size and its surface properties with infrared observations. See our NEO Survey project web site for more details and access to our database.
2017 August 21 Solar Eclipse
See some photos of the eclipse and plans for a solar telescope to safely view the sun and eclipses..
