Research Writing, Statistical Analysis & Manuscript Figure/Data Consultant | M.Tech Biotechnology & Research Associate

Profile Summary

I am a PhD candidate in Molecular Medicine at Semmelweis University with a M.Tech in Biotechnology and over 8 years of experience in biomedical research. I specialize in research writing, statistical analysis, manuscript figure preparation, and data consulting, helping researchers transform complex experimental results into clear, publication-ready outputs. My expertise includes extracellular vesicle and exosome biogenesis, lipidomics, AAV genetic engineering, cloning (assembly, restriction, SDM), BCA and lipid assays, Western blotting, flow cytometry (CytoFLEX, Apogee), super-resolution and confocal microscopy, and Raman spectroscopy. I have contributed to peer-reviewed publications, grant proposals, and meta-analyses, combining hands-on laboratory experience with advanced data interpretation and visualization to support high-quality scientific research.
