Profile Summary

I am a Sports Science researcher and Exercise Physiologist with expertise in exercise performance, sports nutrition, physiological assessment, and evidence-based research methodologies. My work focuses on translating scientific evidence into practical applications for athletic performance, health, and exercise prescription. I have extensive experience conducting systematic reviews, meta-analyses, and advanced statistical analyses using R and other research software. My analytical expertise includes effect size calculations, heterogeneity assessment, publication bias analysis, meta-regression, moderator analysis, and data visualization for scientific publications. I also work with physiological and performance datasets including VO2max, HRmax, intermittent fitness testing, strength performance, and recovery-related variables. My research interests primarily involve: * Sports nutrition and ergogenic aids (especially caffeine supplementation) * Exercise physiology and cardiorespiratory fitness * Resistance training and athletic performance * Female athlete physiology and menstrual cycle research * Team sport performance analysis * Evidence synthesis in sports and health sciences I have contributed to multiple peer-reviewed scientific publications in international journals and have experience preparing manuscripts, responding to reviewers, and assisting researchers with publication-ready analyses and scientific writing. In addition to research, I assist academics, graduate students, and professionals with: * Systematic review and meta-analysis projects * Statistical analysis and interpretation * Scientific writing and academic editing * Data extraction and evidence synthesis * Research methodology consultation * Preparation of tables, figures, and publication-quality outputs I am committed to delivering accurate, transparent, and high-quality scientific work with strong attention to methodological rigor and detail.
