Research Interests

My goal is to address growing technological needs by understanding and controlling the fundamental mechanism of crystallization of polymers during processing. The specific morphology that forms during manufacturing dictates final material properties, so it is crucial to attain control over the type of structure that develops during processing. In my group, we explore the complex interplay between molecular structure, processing conditions, structure development and resulting properties of polymers to enable rational design of material and processes for a particular application. The range of current and potential applications for semicrystalline polymers is extremely diverse, including biomedical devices and implants, solar cells, transistors, film packaging, high-pressure gas piping, high-performance fibers, and structural components, among others.

Areas of interest:

  • Conjugated polymers
  • 3D printing
  • Flow-induced crystallization
  • Nucleation control
  • Biopolymers
