Profile Summary

I am a PhD-trained life scientist and Field Application Scientist with 11+ years of research experience, including 3 years supporting translational biomarker and immunoassay projects across academia, biotech, and CROs. I specialize in scientific writing, data interpretation, assay optimization, and high-quality technical communication for research teams that need expert-level clarity and accuracy. My background spans: Biomarker discovery, immunology, neurodegeneration, oncology Multiplex immunoassays (MSD R-PLEX, U-PLEX, V-PLEX, S-PLEX, ELISA, Luminex) Male and female reproductive biology, embryonic development, fertility AI in life sciences (literature analysis, LLM workflows, data summarization tools) Grant preparation, manuscript writing, translational biology Teaching, training, and scientific communication I’ve delivered 100+ scientific presentations, trained over 100 scientists, authored 12 peer-reviewed publications, and contributed a book chapter on laboratory techniques. I have a strong record of securing research funding through competitive grants and fellowships. My writing style is precise, clear, and grounded in real scientific rigor — ideal for teams needing expert-level communication that resonates with researchers, clinicians, and internal stakeholders.
