PhD degree in applied Microbiology, worked on many subfields of Microbiology (microbial genomics, comparative genomics).

Profile Summary

I am a PhD-qualified microbiologist with over 13 years of academic and applied research experience in microbial fermentation, applied microbiology, and next-generation sequencing–based metagenomics. I am currently a postdoctoral researcher in the UK, with hands-on expertise spanning experimental design, data analysis, and high-level scientific writing. My core expertise includes: Microbial isolation, screening, and characterization for biochemical and biotechnological applications. Amplicon and metagenomics data analysis (QIIME 2, custom pipelines, statistical interpretation). NGS data processing, microbial community profiling, and pathogen detection. Thesis, manuscript, and technical report editing, with strong emphasis on scientific rigor, methodological consistency, and defensible interpretation of results. I have extensive experience reviewing, correcting, and restructuring novice-written theses and manuscripts, ensuring that experimental logic, statistical analyses, and conclusions are scientifically sound and publication- or defense-ready. My approach goes beyond language editing to include critical validation of methods, results, and claims. I work with researchers, students, and R&D teams who need accurate, reliable, and clearly communicated science, particularly where incorrect interpretation could compromise a thesis, publication, or project outcome. I place strong emphasis on confidentiality, academic integrity, and transparent communication.
