My research focuses on the design of precisely controlled polymeric and inorganic materials through advanced synthetic and self-assembly techniques with the ultimate goal of establishing structure-property relationships that enable advanced optoelectronic, lithographic, and information-storage technologies.

One area I am currently exploring while at Cambridge is using state-of-the-art self-assembly techniques such as living crystallization-driven self-assembly (CDSA) to construct hierarchical, low-dispersity π-conjugated polymer nanostructures with controlled dimensions and spatially confined functional groups for advanced optoelectronic applications. By taking additional care and rigor towards assembling these nanostructures we are in essence able to generate new materials from "old" building blocks. While these nanomaterials are fabricated from conventional optoelectronic materials, they exhibit emergent properties due to their well-ordered structure and hierarchical organization, that are otherwise inaccessible in their molecular form.
