How do stars form? How can we use radio waves to probe the origins of stars within their cold, dusty natal clouds? And how do magnetic fields affect the star-formation process? Come and find out how I use CARMA, a millimeter-wave radio telescope in the Eastern Sierras, to find answers to these questions. I will begin by discussing the basics of radio astronomy, radio telescopes, and star formation. I will then talk about the research I've been doing on polarization and magnetic fields in forming stars, using the dual-polarization receiver system that I helped install and commission at CARMA.
