Profile Summary

I am a PhD chemist specializing in polymer science, biomaterials, and nanotechnology, with extensive experience in both academic and industrial research. I trained in the world-renowned Matyjaszewski Polymer Group at Carnegie Mellon University, where I developed molecular bottlebrush polymers for applications such as artificial lubricants, anti-fouling surfaces, and biohybrid materials. My work has been published in leading journals including JACS, Biomacromolecules, and Macromolecules. I bring 8+ years of research and development experience across academia, biotech startups, and industrial labs (including SABIC and NIRvana Sciences). My expertise covers polymer synthesis (RAFT, ATRP, free radical polymerization), small molecule synthesis, and advanced characterization (NMR, FTIR, GPC, DLS, DSC, water contact angle). I also have hands-on experience with polymerization kinetics modeling (Predici) and have developed tools for data analysis and visualization in Python that are already in use by professionals. - Beyond lab-based research, I help clients with: - Technical writing: scientific manuscripts, grant applications, patents, and regulatory documents - Data analysis: experimental data processing, visualization, and interpretation - Research consulting: project design, feasibility studies, and literature reviews in polymers, biomaterials, and nanotechnology - Pitch and presentation support: clear and professional communication of complex science to investors and non-specialist audiences I thrive in multidisciplinary collaborations and enjoy translating cutting-edge science into practical solutions. Whether the need is a technical report, experimental plan, or data-driven insight, I provide precise, reliable, and well-communicated results.
