Research Interests

A protein molecule is made of a long chain of amino acid sequences that fold into a complex three-dimensional structure. It is often the geometrical shapes that determine the protein functions. In molecular biology, researchers use sequence alignment and structure matching to compare the similarity among proteins. Considering proteins as 3D structures, we have developed algorithms to identify geometry-based features to retrieve similar proteins without having to deal with complex chemical characteristics and biological properties. Biologists suggest that, in the next decade a large amount of proteins structures will be derived without knowing its functions. Our work is very promising to help biologists identify the protein functions, which is essential important to drug design and disease prediction.
