Dr. Choi analyses Nanopatterning and Nanostructure Fabrication, where the concentration
is to develop simple but efficient methods of nanofabrication that display superior
pattern regularity, size, and shape over a large area. This research improves
upon standard lithography methods such as e-beam or scanning probe lithography,
which do not cover an area large enough to successfully employ electronic applications.
Dr. Choi is also involved in Biomaterials and Nanobio-Science/Engineering, in
which their well-defined nanostructured surfaces provide a unique opportunity,
whereby the well-controlled surface structures in the nanoscale can elucidate
many aspects of the nanobiology of the cell. It can further lead to novel applications
to bioengineering such as implanting biomedical devices and tissue engineering.
Dr. Choi’s work has resulted in NSF Fellowship, Korea-U.S. Science Cooperation
Center (KUSCO) and Korean-American Scientists and Engineering Association (KSEA)
He has contributed to many publications and conference proceedings, as well
as a book entitled, "Design, Fabrication, and Applications of Large-Area
Well-Ordered Dense-Array Three-Dimensional Nanostructures", Nanostructures
in Electronics and Photonics, Faiz Rahman, Pan Stanford Publishing. (2008).
His research has also recognized as a Research Highlight in the journal Nature,
in which he demonstrates that textured hydrophobic surfaces can achieve slip
lengths almost 10 times longer than previously achieved. Such work could potentially
be used to significantly reduce drag in fluidics applications.
