Takeout and Delivery: Erasing the Dusty Signature of Late-stage Terrestrial Planet Formation
The Astrophysical Journal, 2023 The formation of planets like Earth is expected to conclude with a series of late-stage giant impacts that generate warm dusty debris, the most anticipated visible signpost of terrestrial planet formation in progress.

Discovery and Classification of New Circumstellar Disks from the AllWISE Catalog with Disk Detective
, 2019 In its five years since launch, DiskDetective.org has led to many new discoveries in the field of circumstellar disks. In my dissertation, I present two major emphases of the project: statistical characterization of infrared excess sources from AllWISE ...

L1448 IRS3B: Dust Polarization Aligned with Spiral Features, Tracing Gas Flows
The Astrophysical JournalCircumstellar disk dust polarization in the (sub)millimeter is, for the most part, not from dust grain alignment with magnetic fields but rather indicative of a combination of dust self-scattering with a yet unknown alignment mechanism that is consistent

Discovery of Volatile Gas in the Giant Impact Disk Around the 150 Myr Old HD 23514
The Astrophysical Journal LettersWe report the discovery of CO _2 gas emission around HD 23514, an F5V star in the ∼150 Myr old Pleiades cluster, hosting one of the rare giant-impact disks with unique mineralogy dominated by silica dust. We show that the dust feature remains stable over

Tracing Planets in Circumstellar Disks [PDF]
Proceedings of the International Astronomical Union, 2005 We present simulations which demonstrate to which extent mid-infrared images and millimeter maps can be used to trace the location of giant planets in circumstellar disks. The most promising approach is to look for characteristic signatures in circumstellar disks caused by the interaction of giant planets with the disk.

A λ = 1.3 mm Survey for Disks around Herbig Be Stars
The Astrophysical JournalWe present a survey of 24 Herbig Be stars (young stellar objects >3 M _⊙ ) within 3 kpc at 1.3 mm using the Submillimeter Array at ∼1″ resolution to identify circumstellar disks and assess planet forming potential.
