Polymer Scientist - Biocure Inc.
(2018-01 - 2021-12)
- Synthesized POx-based amphiphilic di- and triblock copolymers via CROP, achieving narrow Đ (<1.2) and tunable MW distributions suitable for high-purity, function-critical applications.
- Scaled polymer production from lab to 10–20 L pilot scale by optimizing monomer feed rates, thermal gradients, and mixing regimes, ensuring reproducibility and tight process control.
- Engineered polymers with tunable HLB and interfacial compatibility for targeted release profiles, surface, and integration into contact, coating, or implantable device platforms.
- Applied DoE to identify and optimize critical process parameters, improving batch consistency, yield, and readiness for controlled manufacturing environments.
- Utilized NMR (¹H, ¹³C), GPC-MALS, FTIR, DSC, and TGA for in-depth polymer characterization to confirm architecture, MW, thermal properties, and degradation kinetics across development stages.
- Developed PVA-based hydrogel systems, including visible light-cured adhesives and contact lens materials, with mechanical and chemical properties optimized for biocompatibility and functional performance.
- Designed and analyzed PVA-conjugated injectable/implantable delivery platforms for peptides/proteins, evaluating hydrogel degradation and sustained release behavior under physiological conditions.
- Employed molecular dynamics, DFT, and modeling tools to predict polymer solubility, conformation, and substrate interactions, enabling data-driven synthesis and formulation decisions.
- Designed and tested nanoscale carriers (liposomes, polymersomes, nanoreactors) from functionalized block copolymers for targeted delivery and biointerface applications.
- Authored SOPs, batch protocols, and technical reports in compliance with GMP, ISO 13485, and ICH Q8–Q10 guidelines; contributed to IP filings and tech transfer documentation for scale-up readiness.
