Astroweiss Group
Astroweiss Group, 2022
L to R: Andrew Langford, Matthias He, Alex Thomas, Lauren Weiss, Aaron Householder, Casey Brinkman, David Shaw.
The astroweiss group includes postdoctoral scholars, graduate students, and undergraduate students who are studying diverse topics related to exoplanet system architectures and planetary compositions and formation. Group members are currently supported at two sites: University of Notre Dame and University of Hawaii, Manoa.

Keck Planet Hunter Collaboration
My extended research group includes investigators from various universities who are using the W. M. Keck Observatory to discover and characterize exoplanets and their host stars with high-resolution spectroscopy. Group activities include frequent observing on Keck, observer training, data management, and of course, analysis of the planets and stars that are so dear to us!
