Margaret, 84. Active trial participant since 2019.

Aging is not a disease.
It is a subject worthy of serious attention.

The Longevity Research Center studies how human bodies age — measuring telomere erosion, tracking sarcopenia progression, and designing interventions that add function to years.

Measuring the mechanisms
of biological aging.

Three active research programs. One shared question: how do we extend the years when life is still fully lived?

Telomere length as a window into cellular age.

We measure telomere length via quantitative PCR across longitudinal cohorts, correlating erosion rates with inflammatory cytokine profiles and functional decline markers.

847participants
Participants with telomere lengths in the top quartile at enrollment showed 34% lower incidence of mobility impairment at 5-year follow-up.

Tracking muscle loss across a decade.

Dual-energy X-ray absorptiometry (DEXA) and grip-strength dynamometry track muscle mass and functional capacity across a 12-year cohort of adults aged 65–92.

12yrlongitudinal span

Identifying cognitive decline before it becomes visible.

Neuropsychological batteries combined with fMRI connectivity mapping identify early signatures of cognitive reserve depletion, enabling earlier clinical intervention.

We're not studying how people die. We're studying how people continue to live — and what the body needs to do that with dignity.

"My patient returned from her first visit with a printed summary I could actually use. Her MMSE held. Her gait speed improved. I've referred four more since."

of STRIDE-2 participants maintained or improved functional independence scores at 18-month follow-up.

"The question we ask is not 'how long?' but 'how well?' Our biomarker panels are designed to predict function, not just survival — because those are different outcomes with different interventions."
