PhD Toxicologist & Medical Writer | Translating Complex Science into Clear, Impactful Communication

Profile Summary

I’m a PhD-trained toxicologist and molecular biologist with expertise in translational neuroscience, nonclinical regulatory writing, and visual science communication. My background spans early-stage drug development, with hands-on experience designing and executing in vitro and in vivo experiments, analyzing complex RNA/DNA data, and translating preclinical findings into actionable insights for therapeutic advancement. I’ve worked on neurodegenerative disease pipelines, contributing to IND-enabling research, and supported a pharmaceutical nonclinical team through the preparation and review of regulatory documents. I also bring a strong foundation in scientific communication—skilled in crafting precise, engaging content for both technical and general audiences. My training includes a workshop in visual science communication, and I’m passionate about making science more accessible and impactful. Whether you’re looking for support with regulatory writing, medical writing, or scientific editing, I bring scientific rigor, clarity, and a collaborative mindset to every project.
