I am Daniel Alexander van Skye, DBA, a Human Performance Scientist working at the intersection of Human Performance, Data Science, and elite professional tennis. I design player-specific digital human performance systems that model readiness, recovery, and fatigue dynamics with scientific precision.

My work integrates longitudinal tracking of HRV, load reactivity, hormonal rhythms, sleep architecture, hydration balance, metabolic efficiency, respiratory dynamics, thermal strain, RPE, and environmental stress. I aggregate, analyze, and translate these signals into an actionable performance intelligence layer that provides clear, time-accurate guidance for athletes and their coaching teams.

I provide Pro Player Support for top-tier ATP and WTA athletes, delivering data systems that guide decision-making across the professional tennis calendar. All my services are designed to function as a travel-based performance lab, ProTourLab™, enabling my seamless integration into coaching teams and availability to travel the tour. From training-load planning and taper calibration to travel adaptation and match-day readiness forecasting, every recommendation is aligned with the athlete’s biological state. The objective is to sustain resilience, preserve readiness, and optimize performance stability under the demands of the tour.

Human Performance Engineering transforms raw signals into structured logic. Human Data Science provides the analytical depth to decode complex variability and refine interventions. Together, they create a framework that allows players and coaching teams to act with clarity in high-pressure environments.
