Welcome to PolyNEL!

PolyNel Labs research image

Our research focuses on polymeric and bio-based materials, nanotechnology, surface and interface engineering, and transport modeling. Central to this research program in polymer and surface engineering is the design of well-defined molecules, including chemical functionality and molecular architecture. Our group performs fundamental research activities in polymer and particle synthesis, surface and interface modification, grafting chemistry, and material characterization. Applications for our polymer and nano-materials include energy, water remediation, drug delivery, and advanced separations/sensing.
