A QUESTION THAT CONNECTS OUR WORK
The answer begins in our cells. It also lives in how we move, recover, think, and engage with the world.
At the Abadir Lab, we study frailty and resilience across these scales. We investigate mitochondrial signaling, inflammation, and metabolism, then connect that biology with clinical measurements and emerging technologies.
Our work brings laboratory discovery into conversation with the everyday needs of older adults.

THE MOLECULAR FOUNDATION
Our research into the renin–angiotensin system (RAS) and mitochondrial function connects cellular mechanisms with vascular aging, frailty, and resilience.
THE WEEKLY COLUMN
A closer look at AI, molecular biology, and the research shaping later life.
All editionsAn AI exercise coach, a changing ovarian proteome, an experimental gene target, and a practical way to prevent falls raise a shared question: what does it take for a promising idea to become useful in an older person’s life?
CONNECTED RESEARCH
Explore the work at the heart of the lab.
Mitochondria, angiotensin signaling, and inflammatory pathways.
Molecular markers, metabolism, and physical and cognitive function.
Targeted drug delivery, tissue repair, and clinical investigation.
GERIATRICS + ENGINEERING
A place where clinical needs shape the next technology.
At Johns Hopkins, Geriatrics Engineering creates space for clinicians and engineers to work side by side. The Bayview hub connects laboratories, a model apartment, and technologies for studying everyday function.
