The Jones Laboratory works on a problem with high stakes and unanswered questions: why does cardiometabolic disease so reliably destroy the heart, and what are the molecular events that make that progression either reversible or permanent? Our answer involves metabolism, the extracellular matrix, inflammation, and integrative physiology—four lines of inquiry that, in this lab, are treated as one.

Pillar 1: Metabolic Control of Cardiac Remodeling

The heart under stress is a metabolic problem as much as a structural one. When cardiometabolic disease disrupts how the heart senses nutrients, manages redox balance, and interprets metabolic signals, the downstream consequences show up as impaired survival, pathological growth, and contractile failure.

We hunt for the checkpoints—the specific moments in metabolic signaling where the heart's response tips from adaptive to destructive. Find those, and you've found something worth targeting. That's the work, and it runs across models of pressure overload, ischemia-reperfusion injury, and metabolic disease. If you're drawn to asking why the heart fails at a mechanistic level rather than just describing that it does, this line of inquiry will suit you.

Pillar 2: Extracellular Matrix–Immune Crosstalk

Most people learn about the extracellular matrix as scaffolding. That framing undersells it badly. The matrix is an active, dynamic signaling environment—and in the heart, it helps determine who gets recruited, how immune cells behave, and whether inflammation resolves or becomes the problem.

Our work centers on hyaluronan: a matrix-derived molecule that sits at the intersection of metabolism and immune regulation and turns out to be a surprisingly powerful driver of cardiac pathology. We study how changes in matrix composition shape fibrotic remodeling and ventricular stiffness, and how immune and resident cardiac cells talk to each other through matrix-mediated signals. This is a line of research where the biology keeps revealing new layers—genuinely open territory for a trainee who wants to be the one doing the revealing.

Pillar 3: Integrative Cardiovascular Physiology

Molecular findings that don't hold up in living systems aren't findings—they're hypotheses. Physiological rigor is non-negotiable in this lab. Every project is anchored to in vivo models and phenotyping methods that force us to ask whether what we observe in a cell or a pathway actually matters to how a heart performs.

That means echocardiography, pressure-volume assessment, cardiac functional analyses, and tissue-level approaches that connect signaling to outcome. Training here means you will not be a bench scientist who has never seen a heart beat in real time, or never wrestled with the complexity of translating a molecular observation into a physiological claim. That integrative discipline separates strong cardiovascular scientists from narrow ones.

Pillar 4: Rigorous, Reproducible Translational Science

Rigor isn't a constraint on creativity—it's what makes discoveries worth believing. The Jones Laboratory invests heavily in experimental design, reproducibility, and standardized methodology, including through shared research core infrastructure that extends our approaches to the broader scientific community.

This also reflects a translational orientation: we pursue our questions with an eye toward human disease. Trainees in this lab learn to design experiments that hold up, not just ones that yield results. That distinction matters for a scientific career.

An Integrated Research Program

These pillars aren't silos—they're angles on the same problem. Metabolic dysfunction alters the matrix; the matrix instructs immune behavior; immune activity determines whether the heart remodels adaptively or fails. Physiology is the thread that runs through all of it and keeps the work honest.

The lab's goal is to define the unifying mechanisms that drive cardiometabolic heart disease—and to do it rigorously enough that the findings point somewhere therapeutically real. If that kind of integrative, mechanism-first science is what you're looking for in a training environment, read about the people doing the work and what we've published. Then reach out.

Our research program is supported by the National Institutes of Health, the American Heart Association, and other national funding organizations, and is embedded within a collaborative environment that values scientific clarity, mentorship, and leadership.
