We utilize the tools of synthetic chemistry, supramolecular chemistry, and nanotechnology to design dynamic materials, addressing fundamental scientific challenges and presenting unique opportunities to overcome obstacles in contemporary materials science. I am particularly focused on developing molecular design strategies to manipulate dynamic properties across different length scales, from the molecular to the macroscale, in polymer and composite materials. Ultimately, through the development of 'Molecularly Intelligent' dynamic materials based on a deep fundamental understanding, one of our long-term goals is to create soft material systems that mimic biological systems, exhibiting unprecedented dynamic properties such as self-healing, stimuli-responsiveness, and autonomous 3D assembly.
