Freelance Biostatistician & Medical Writer | Python Data Analysis | AI & ML for Biosciences

Profile Summary

I am a freelance Biostatistician, Data Scientist, and Medical Writer with over 10 years of experience in clinical research, life sciences, and academic projects. I specialize in biostatistics and data analysis using Python, applying advanced statistical modeling, machine learning, and deep learning to biological and clinical datasets to transform complex data into clear, actionable, and publication-ready insights. Throughout my career, I have conducted statistical analyses for experimental studies, performed data cleaning, modeling, and interpretation, developed AI applications for biological data, and created high-quality data visualizations and scientific figures for publications. I also provide support in manuscript preparation, scientific editing, medical and technical writing, and the development of comprehensive research reports. By combining strong analytical expertise with scientific communication skills, I ensure that results are methodologically rigorous and clearly and professionally presented for academic journals, regulatory documentation, and commercial reports. I am available for short- and long-term collaborations with researchers and organizations seeking reliable expertise that integrates data science with high-level scientific writing. All primary analyses and written content are developed personally by me, with AI tools used only when appropriate for limited and repetitive support tasks, ensuring full methodological integrity, originality, and strict data confidentiality.
