Genetics, microRNA, Dicer, Lin-4 microRNA precursor and Cell biology are his primary areas of study. His Genetics research focuses on subjects like Computational biology, which are linked to Transcription. His microRNA study combines topics from a wide range of disciplines, such as Regulation of gene expression, Downregulation and upregulation, Stem cell and Biogenesis.

His Dicer study incorporates themes from Microprocessor complex and Drosha. V. Narry Kim has researched Lin-4 microRNA precursor in several fields, including DGCR8 and Gene silencing. His studies in Cell biology integrate themes in fields like Protein biosynthesis, mRNA surveillance, Messenger RNP, RNA-binding protein and Five-prime cap.
