Personal profile
Research interests
I am an astronomer and Senior Lecturer in Data Science in the Department of Physics, Astronomy, and Mathematics. I research the formation of stars, using multiwavelength observations (from X-ray to optical to radio) to investigate nearby star-forming regions and the young stellar objects (YSOs) that reside therein.

Several highlights include:
• Demonstrating that most clusters of young stars are expanding and gravitationally unbound (Kuhn et al. 2019, ApJ, 870, 32)
• Compilation of the Spitzer/IRAC Candidate YSO (SPICY) catalogue, one of the largest catalogues of disk-bearing young stars (Kuhn et al. 2021, ApJS, 254, 33)
• Discovery that a segment of the nearest Milky Way spiral arm (visible to the unaided eye at night) is not where it was expected to be, and instead forms a spur extending out of the arm (Kuhn et al. 2021, A&A Letters, 651, 10)
I am actively engaged in astrostatistics, and since 2019, I've been a member of the Cosmostatistics-Initiative (COIN).
