Hilary Brueck is a Health Correspondent at Business Insider.
Hilary covers longevity and the quest to improve human aging. She also writes regularly about infectious diseases, new treatments and cures for various illnesses and conditions, vaccine safety, and mental health.
In general, she relishes any opportunity to unpack human health mysteries or examine the latest health-related discoveries. Her reports have ranged from exploring how sherpas effortlessly climb into the thin air 29,029 feet above the sea to summit Mount Everest, to trudging along a Jersey shore beach with scientists fighting killer pandemic flu viruses by studying bird butts.
She's spoken with Dr. Anthony Fauci about his vitamin and supplement routine over a cold slice of pizza, and chatted with the world's oldest Nobel Prize winner in his basement solar lab. She also went an entire month without eating any ultra-processed foods (yes, it was a terribly time-consuming and challenging endeavor.)
A graduate of Columbia Journalism School and former Peace Corps Volunteer, Hilary speaks English, French, and Malagasy. Previously, Hilary reported for ABC News Radio, Fortune, Forbes, and Al Jazeera America.
