Postdoctoral Scholar · UC Santa Barbara

I am a polymer physicist and computational scientist developing models to engineer soft materials that are safe, renewable, and reusable. By integrating statistical mechanics, multiscale simulation, and ML-assisted computation, my work connects microscopic physics to material behavior to accelerate the design of sustainable polymers and responsive materials.

Sustainable Plastic Materials using Ionic Interactions

Chemically dissimilar polymers usually don't mix, which limits the extent of plastic recycling. By functionalizing existing polymers with acid/base moieties, one can promote mixing through the favorable electrostatic interactions. The combination of electrostatics and the reversible nature of the proton-transfer reaction requires novel theories to guide experimental design. My work develops theories and computational models to navigate the vast design space for functionalization. This work is in concert with synthesis and characterization efforts as part of the Materials Research Science and Engineering Center (MRSEC) at UCSB.

Compatibilization

Electrostatic Control of Glassy Systems

Glassy and slowly relaxing materials are central to technologies ranging from structural polymers to functional coatings, yet the nonequilibrium nature of their processing makes their microstructures difficult to control. Long-range electrostatic and dipolar interactions provide a way to influence this process. My work investigates how these interactions can accelerate dynamics and tune characteristic length scales during early coarsening, enabling controlled morphologies.

Glassy Polymers

Statistical Mechanics of Supramolecular Soft Materials

Supramolecular materials assemble via reversible (non-covalent) linkages that underpin exciting material classes, such as self-healing materials or stimuli-responsive gels. Describing these reversible systems is difficult due to the interplay between of chemical degrees of freedom (composition, conformation, interactions) with bonding network topology. My work extends a class of field theories known as coherent states to a broad set of polymer systems, including those with multiple components and competitive reactions.
