PhD Microbiologist | Scientific Manuscript & Grant Editing (Microbiology & Immunology) | +30 publications

Profile Summary

I am a PhD Microbiologist with 20 years of research experience and 36 peer-reviewed publications in international indexed journals. I provide advanced scientific manuscript editing in microbiology, immunology, gut health and animal health sciences. My service goes beyond grammar correction. I focus on: • Improving scientific clarity and logical flow • Strengthening discussion and argument structure • Refining introduction framing and hypothesis positioning • Ensuring methodological consistency • Aligning manuscripts with journal expectations As an experienced peer reviewer and grant contributor, I evaluate manuscripts from an editorial perspective, identifying weaknesses that may affect acceptance. I work with researchers, graduate students and biotech professionals who want their work to be publication-ready and scientifically rigorous.
