Title: A polarized view of the multi-messenger universe
Abstract: Over the past decade, multi-messenger astronomy has reshaped our view of the high-energy universe. While gravitational waves and cosmic neutrinos have explored many key physical properties of black holes and neutron stars, the plasma dynamics and magnetic field structures in these compact object systems are not yet well studied. Polarimetry provides a direct probe of magnetic field dynamics, geometry of the plasma, radiation mechanisms, and plasma physics across multi-messenger sources. Enabled by the recently launched Imaging X-ray Polarimetry Explorer (IXPE) and upcoming observatories like the Compton Spectrometer and Imager (COSI) in the MeV gamma-ray band, multi-wavelength polarimetry is entering a transformative era. This talk presents the unique scientific breakthroughs achievable through multi-wavelength polarimetry, demonstrating its role as a fundamental pillar of modern multi-messenger astrophysics
Keywords: Polarimetry, plasma dynamics, neutrino, relativistic jet, blazar, gamma-ray burst

Title: Experiments on the Cheap
Abstract: 
According to the American Institute of Physics, a little under half of the ~600 new Physics faculty hires in 2023-2024 were into departments with no graduate program. The total number of Physics and Astronomy PhDs awarded in that year was about 2,000 (a 1.5% decrease from the previous year). Graduate students and post-doctoral scholars looking for a faculty position may land in a bachelor's only institution. These departments often operate with very limited funds and securing external grants in this space can be exceptionally difficult. What skills and knowledge are useful when trying to design something that looks like experimental research when your budget may be "thoughts and prayers"? In this talk I'll outline some of the lessons I've learned in my time at a regional, 4-year, public school. These lessons have proven valuable in both the research and teaching labs.
