Freelancer Overview

As a Cell and Molecular Biologist with a Ph.D. and 5+ years of postdoctoral experience at Columbia University, I bring extensive expertise in data validation, quality control, and analytical method development that directly translates to AI training. My background includes rigorous experimental design, comprehensive statistical analysis, and meticulous documentation practices, demonstrated through peer-reviewed publications including a 2025 PNAS paper. My specialized knowledge spans mammalian cell culture, CRISPR gene editing, advanced microscopy, and protein characterization - areas where AI systems need expert guidance. With experience delivering 15+ scientific presentations and collaborating with diverse research teams, I excel at identifying errors in scientific content and communicating complex biological concepts clearly, making me well-equipped to train AI systems on biological accuracy and methodology.
