Active PhD researcher in cardiovascular physiology, peer-reviewed author, and public communicator on health and performance. The same standard — honesty, mechanism, evidence — runs through all of it.
My research centers on neural and autonomic cardiovascular control — specifically how the sympathetic nervous system regulates blood pressure during physiological stress, including exercise, pain, and environmental extremes.
Current projects include investigating muscle sympathetic nerve activity responses to hyperbaric exposure in partnership with the Naval Submarine Medical Research Laboratory, and coordinating a NIH- and AHA-funded randomized clinical trial examining home-based training interventions in adults at cardiovascular risk.
The tools I use in research — Python pipelines, R statistical frameworks, reproducible code published on GitHub — are the same tools I bring to consulting work.

Americans live longer than the global median but spend more of those extra years in reduced health. The gap between total life expectancy and healthy life expectancy is 12.5 years in the United States compared to 9.3 years globally.
This figure was built in R using WHO HALE data. It is used in consulting and coaching work to frame the mission: the goal is not just more years, but more capable years.

Abnormal blood pressure responses to exercise are strong independent predictors of cardiovascular morbidity and mortality. Higher cardiorespiratory fitness is associated with lower submaximal exercise BP across populations. This review synthesizes evidence on the prognostic value of exercise BP, its relation with fitness, and its response to exercise interventions, and proposes a clinical model for integrating exercise BP as a modifiable risk factor.

Mechanistic overview of the "third compartment" and sweat sodium kinetics. The eccrine sweat gland secretory coil utilizes dermal sodium as its precursor fluid. Secretion rate outpaces ductal reabsorption capacity at high flow, leading to progressive net sodium loss. Published in Exerc Sport Sci Rev, 2026.
Nine in ten adults exceed recommended sodium intake. Excess dietary sodium increases blood pressure during exercise and contributes to future cardiovascular disease. This review synthesizes evidence that sweat-inducing interventions could facilitate meaningful sodium losses through dermal excretion, representing a novel strategy to attenuate cardiovascular strain independently of renal function.

All analysis pipelines are published on GitHub with documentation and example data. Built to replace manual processes that were taking hours and introducing error.
Replaced manual copy-paste across 80+ Excel files. Python, point-and-click GUI, automated Z-score flagging.
Batch extraction from Hologic DXA PDF reports. Handles four proprietary report variants with font encoding artifacts.
Paired DeLong tests, Youden's J, bootstrap confidence intervals, ggplot2 ROC curves. R and Jupyter.
Modeled sodium loss across temperature and humidity gradients. Published alongside the ESSR review paper.
The same rigor I apply in the lab applies to the systems I build. If that matters to your organization, let's talk.
