I study star formation using multiwavelength observations (X-ray, optical, infrared, and submillimetre), employing methods from statistics and machine learning to obtain astrophysical results. I am interested in questions like: "What controls star-formation rates?", "Which star-formation events produce gravitationally bound star clusters?", and "How do stars assemble their masses?"

In astrostatistics, I am interested in statistical modeling, especially mixture models and spatial point processes.

Sgr Arm Structure
A chain of star-forming regions was found jutting out from the Milky Way's Sagittarius Arm. The inset shows the size of the structure and distance from the Sun. Each orange star shape indicates star-forming regions that may contain anywhere from dozens to thousands of stars.

W40 Spitzer mosaic
Giant gas bubbles form the characteristic butterfly-like shape of the W40 star-forming region seen in this Spitzer Space Telescope image. Hundreds of young stars were identified in this region by a combination of X-ray, optical, and infrared observations.
