    Postdoctoral Research Associate and Adjunct Faculty

    University of San Diego

    Development of amphiphilic polymeric hybrid biomaterials based on starch for applications in the field of protein repellency, antifouling coatings, drug release and hydrogels.

    • Developed and synthesized polyurethane based hybrid copolymers with high starch content via graft to- technique.
    • Studying protein repellency of a series of hybrid copolymers with different starch content using Quartz Crystal Microbalance with Dissipation (QCM-D).
    • Development of polynorbornene grafted starch hybrid copolymers via ROMP and understanding small molecule loading and release of these systems.

    In the pipeline: Starch based hydrogels for peptide delivery, development of cross-linked starch hybrid systems for small molecule release.

    Postdoctoral Researcher

    Polytechnic Institute of NYU

    Development of fluorinated polymeric materials based on aromatic and aliphatic systems using radical polymerization techniques and understanding structure - property relationships via different characterization techniques for potential application in plastic optical fiber (POF).

    • Successfully developed polymers based on trifluoromethoxystyrenes and investigated structure – property relationships.
    • Design and development of small substituted aromatic systems (dopants) to control the refractive index profile of polymers for graded index plastic optical fibers (GI POF).
    • Successfully developed a series of highly chlorinated organic dopant molecules as per glass transition temperature and refractive index profile requirements in poly (pentafluorostyrene).

    Involved in large scale synthesis (kilograms) of precursors for different monomers.

    Graduate Student

    City University of New York

    Synthesis of heteroatom (B, Si, Ge, Sn) containing fluorescent conjugated inorganic – organic hybrid polymers/macrocycles using Acyclic Diene Metathesis (ADMET) for application in organic electronics.

    • Successfully used ADMET as a synthetic strategy over a wide variety of monomers based on different heteroatoms (B, Si, Ge, Sn) and aromatic systems (styryl, substituted styryl, thiophene).
    • Designed and developed multi-step synthetic strategy to achieve the goal of developing a library of unique monomers and polymers.
    • Derived structure – property relationship for the different conjugated polymeric systems from an electro-optical perspective for potential application in organic electronic devices.

    Utilized different characterization techniques for structural elucidation of monomers and polymers.
