Ashley Prosper, MD

I am a cardiothoracic radiologist at UCLA, providing image-based care for patients’ lungs, hearts and blood vessels. I am committed to increasing awareness of image-based screening because it helps us find diseases earlier, when we have more opportunities to improve outcomes. When I’m not at work, you may find me working on a new recipe or traveling with friends and family.
