In LIST2026, two-year-old mice expressing a GH receptor antagonist lived longer and were less frail — but also had increased adiposity, reflecting Berryman's long-running argument that fat tissue quality/distribution, not just quantity, drives metabolic outcomes under altered GH signaling. In DUR2026, adult-onset GH receptor deletion improved insulin sensitivity in males, and single-cell liver sequencing revealed sex-dimorphic remodeling.

Trained as a nutritional scientist at Cornell after a biology degree at UVA, she later earned dietetic credentials — unusual among molecular biologists. She built her program on how GH excess/deficiency reshapes adipose tissue.

She now serves as Associate Dean for Research and Innovation and has held interim leadership of the renamed Institute for Molecular Medicine and Aging.
