Personal Physiodata Scientist to WTA players
I design advanced physiometric data systems for the elite demands of professional women’s tennis. My work builds real-time performance data models of HRV dynamics, hormonal phase transitions, training load reactivity, and environmental stress to support physiologically informed decision-making across the WTA calendar.
Each athlete operates on a unique and evolving internal rhythm. I translate that rhythm into structured forecasts, readiness logic, and adaptation protocols that align with training plans, travel cycles, and tournament demands. The goal is not simply to monitor physiology, but to decode its signals and convert them into tactical insight.
The precision performance systems I design use AI-supported physiodatalytics and adaptive data modeling engines that learn from longitudinal inputs. These systems recognize patterns in vagal tone recovery, endocrine fluctuations, and surface-specific fatigue accumulation. Each of these factors can suppress readiness or distort performance if not identified and adjusted for in time.
I specialize in building athlete-specific data ecosystems that are non-intrusive, scientifically rigorous, and seamlessly integrated into the decision-making of the coaching team.
Modeled from her data. Calibrated for her demands.
