The research in our group is in the area of organic and bioorganic chemistry, and currently focuses on the development of nucleic acid analogs capable of targeting single-stranded RNA or double-stranded DNA in a sequence-specific fashion. To achieve the objective, synthetic organic chemistry and analytical chemistry are conducted.
