プロフィール概要

I am a medical researcher and clinical research consultant with 40+ peer-reviewed publications and conference outputs across cardiovascular medicine, internal medicine, perioperative medicine, nephrology, endocrinology, respiratory medicine, surgery, and evidence-based research. My work focuses on clinical research, evidence generation, medical writing, real-world evidence, systematic reviews, meta-analysis, network meta-analysis, observational studies, and R-based statistical analysis. I support projects from the early research idea to protocol development, literature search, screening, data extraction, risk-of-bias assessment, statistical analysis, manuscript writing, abstract/poster preparation, journal submission, and response-to-reviewers. I have experience using R, RevMan, SPSS/Jamovi, Excel, Rayyan, EndNote, Word, PowerPoint, and Canva. I also work with PRISMA, PICO/PICOS, GRADE, risk-of-bias tools, STROBE-style reporting, and reproducible research workflows. My ongoing and recent research work includes cardiovascular outcomes, electrophysiology, heart failure, interventional cardiology, perioperative outcomes, real-world database studies, and digital health interventions for guideline-directed medical therapy in heart failure with reduced ejection fraction. I also mentor students and early-career researchers in topic selection, study design, data extraction, analysis interpretation, academic writing, and publication planning. In addition, I serve as a peer reviewer for 15+ journals, including BMC Cardiovascular Disorders, BMC Nutrition, Frontiers in Cardiovascular Medicine, Egyptian Heart Journal, Scientific Reports, and others. My working style is organized, detail-oriented, responsive, practical, and focused on producing clear, rigorous, publication-ready outputs.
