Profile Summary

I am a medical doctor and Vascular Surgery Resident with a deep commitment to evidence-based medicine and high-impact clinical research. Currently, I am a Master of Science (MSc) candidate in Clinical Epidemiology at Universidad de los Andes. My professional trajectory is defined by a unique synergy between specialized surgical practice and rigorous scientific methodology. Over the past five years, I have actively led and contributed to research projects funded by national government grants (MinCiencias) and prestigious institutional awards. Notably, I serve as a lead researcher for "Multigraft-bac," an innovation project focused on developing regenerative vascular grafts with antimicrobial and antithrombotic properties. My contributions to the field have been recognized globally, most notably receiving the Paul Dudley White International Award from the American Heart Association (2024). I have contributed to high-impact global science with over 1,060 citations in Google Scholar and an h-index of 8, reflecting the clinical and methodological relevance of my work in leading journals such as The Lancet- Regional Health Americas, Journal of Endovascular Therapy, and BMJ Open. This proven track record of scientific influence ensures that I deliver evidence-based results that resonate with the international medical community. My technical expertise encompasses: -Advanced Biostatistics & Data Analysis: Proficient in medical data interpretation and statistical software. -Clinical Research Design: Expert in developing protocols for multicenter prospective cohorts and clinical trials. -Evidence Synthesis: Certified in Systematic Reviews and Meta-Analyses by Johns Hopkins University. -Scientific Writing & Peer-Review Strategy: Extensive experience in preparing manuscripts for top-tier journals and presenting results at international congresses such as the SVS Vascular Annual Meeting and VEITH Symposium. I am fluent in English (C1/TOEFL iBT 102) and offer specialized consulting services for research institutions, med-tech startups, and clinical teams looking to bridge the gap between raw medical data and high-quality, publishable scientific evidence.
