Karen started her career as a health policy reporter in the nation's capital, where she covered congressional hearings on Medicare and Medicaid. From the late 90s to the early aughts, she reported on health business for Reuters Health and contributed to its medical and consumer health newswires. Prior to that, she was Modern Healthcare's New York Bureau Chief. A fellow of the Association of Health Care Journalists' 2019 class on Comparative Effective Research, Karen is committed to helping people understand the benefits and harms of clinical interventions and exposing racial/ethnic disparities in healthcare. When not on deadline, you might find her whipping up something in the kitchen, working out, bingeing on cable news, or indulging in some form of mind candy (aka reality TV).
