He has been working on RNA sequence problems since 1996. His main interest is using combinatorial methods to design RNA sequences for secondary structure prediction. His RNA prediction research focuses on certain lattice (or random) walks that are used in a way to code strands of RNA that would be essential for the identification of specific viral RNA molecules. He is currently working on a lattice walk model for RNA sequence prediction with applications to RNA sequences related to HIV, malaria and yellow fever. Further interests of his are in analyzing simple sequence repeat patterns in DNA sequences, as well as evaluating RNA folding rates.
