My main research interests aim to achieve scalable ionic polymer thin films for iontronic device applications. In particular, the uniform and reliable fabrication of functional polymer layers over large-area is crucial to achieve high-performance iontronic devices, such as memristors, actuators, and adhesives. However, some remaining challenges, such as bad interfacial contact and low-processability of conventional solvent polymerization have hindered further progress. My lab will apply initiated chemical vapor deposition (iCVD) technique for solvent-free and scalable polymer film fabrication, based on the capability of low-temperature process and conformal coatings on complex surfaces over large areas. In addition, chemical versatility of iCVD process will enable for improved electrochemical stability, mechanical properties, and ion conductivities. I anticipate that the applications of this research will be numerous and diverse, for the simple reason that understanding of ion-transport properties has immediate relevance to anything that involves bio-inspired neural networks. Graduate and undergraduate students will gain experience in vacuum deposition techniques, polymer film fabrication and also learn about ion transport and device physics of soft-iontronic devices.
Teaching Interests. My teaching approach focuses on creating a safe and non-judgmental environment where students can comfortably communicate and engage with one another. My goal is to equip students with the necessary skills for critical reading, solid hypothesis formation, and effective writing that extend beyond my course. Recognizing the importance of social interaction, especially in challenging times like the COVID-19 outbreak, I utilize peer group discussions and various communication channels to effectively engage with students and promote active learning strategies through cooperative problem-solving. Through my teaching strategies that advocate for an egalitarian approach to education, where students actively participate in the learning process, I aim to inspire a passion for critical thinking and equip students with tools for lifelong learning. By examining hypotheses, analyzing evidence, and connecting scientific principles to daily activities, students will be prepared for future scientific endeavors.
