Kerry Grens is the senior health and science reporter at WHYY, Philadelphia's NPR and PBS affiliate. Her stories span the beat, from the manufacturing of pharmaceuticals in goats to the role of fire in the New Jersey pine barrens, to the culling of community hospitals. She has been reporting for WHYY since February 2007.

She moved to Philadelphia in 2006, when she joined The Scientist as a staff writer. For more than a year the magazine sent her on reporting trips around the country to write about discoveries in the life sciences.

Her return to radio was a return to her first love. Grens started in journalism through a AAAS science writing fellowship at KUNC, an NPR affiliate in Greeley, Colorado. Following that she spent two years as New Hampshire Public Radio's health and science reporter. She has a master’s degree in biological sciences from Stanford University, where she did research in neuroscience, and a bachelor’s in biology from Loyola University Chicago. Her stories appear on WHYY-FM during Morning Edition and All Things Considered and on WHYY-TV during Delaware Tonight.
