Research Interests

The Responsive and Programmable (R+PM) Group is generally interested in realizing functional utility in soft materials. Our research is highly interdisciplinary, bridging chemical engineering, materials science, polymer science, mechanics, optics, and applied physics. 听

Research Keywords:

polymers, liquid crystals, soft matter, actuation, robotics, optics

Brief Summary of Research Activities:

Current research activities in the R+PM Group are broadly focused on harnessing stimuli response in liquid crystalline materials to realize shape transformation or optical reconfiguration. Ongoing research is largely focused on exploiting the anisotropy of liquid crystalline materials to enable distinctive function as material actuators, reconfigurable optical elements, ruggedized substrates for flexible electronic devices, and as novel mechanobiological scaffolds. Exploiting techniques in directed self-assembly of liquid crystalline materials and enabled by our advancements in materials chemistry, we are undertaking foundational studies of material behavior and exploiting this new knowledge to further optimize and enhance response.
