Research Interests:

My current research aims to develop a versatile polymer-based spin-on doping process of semiconductors. While a polymeric spin-on doping process offers a hybrid between conventional inorganic spin-on doping and a monolayer doping procedures, there are opportunities to improve adhesion with the target materials and precision of locating the dopant in nanoscale. To address these issues, I am working on functionalizing and tailoring self-assembled nanostructures of dopant-containing homopolymers and block copolymers (BCPs).


Originally from Kawasaki, a suburb of Tokyo, Japan, I received my B.E. and M.E. in organic and polymeric materials at Tokyo Institute of Technology (Tokyo Tech).  Then I moved to the University of Texas at Austin (UT Austin) with support from the Takenaka Scholarship, and received my Ph.D. in Chemical Engineering. I was fortunate to discover my passion for polymer physics and processing at an early stage in my academic career.  From my senior year and through my Master’s degree at Tokyo Tech, I studied the origin of residual stresses in solvent-cast polymer films, focusing on glass transition of the polymer solution in the Ougizawa group. At UT Austin, with the direction of Professor Christopher J. Ellison, my graduate work was dedicated to polymer thin films, ranging from purely fundamental studies to applications. On the fundamental side, I studied the dynamics of nanoconfined polymer thin films using a fluorescence technique. On the application side, I employed a mussel-inspired polymer, polydopamine, as a universal adhesive layer for block copolymer (BCP) nanopatterning on flexible substrates. Also, I developed a wetting transparency-assisted BCP lithography process to pattern a large-area graphene nanoribbon array for mid-infrared plasmonic devices. When I’m not in the lab, I enjoy playing softball/flag football/dodgeball, listening/playing music, and reading books.
