Scientific Consultant & Technical Writer | Chemistry PhD. 10 years research experience in organic & medicinal chemistry

Profile Summary

I help researchers and companies make sense of complex scientific questions, evaluate the available evidence, and identify the most important next steps. I completed my PhD in chemistry in 2020 and have spent the past ten years working across chemistry, microbiology, and pharmaceutical research in the United States and Germany, including five years of postdoctoral research focused on antimicrobial drug discovery. My work has involved medicinal chemistry, microbiology, fragment-based drug discovery, structure-activity relationship studies, biological and enzymatic assays, biofilm inhibition and eradication assays, experimental design, chemical analysis, and data interpretation. Research projects have included antimicrobial resistance, bacterial pathways, and drug discovery efforts involving organisms such as Escherichia coli, Klebsiella pneumoniae, and MRSA. In addition to laboratory research, I have experience in scientific writing, technical writing, grant writing, manuscript preparation and editing, literature reviews, fact-checking, and communicating complex scientific information to diverse audiences. I am available for scientific consulting, literature reviews, technical writing, research support, data interpretation, experimental planning, and project-based R&D collaboration.
