Dr. Jingyu Hou has been undertaking research in bioinformatics, especially in protein function prediction from protein-protein interaction (PPI) networks for many years. Dr Hou is part of a strong bioinformatics research team from Deakin University in Australia and has published many high quality journal and international conference papers. Particularly for protein function prediction, Jingyu's research team has proposed and published various innovative algorithms to dynamically predict protein functions from PPI networks. These algorithms refer to many critical aspects of protein function prediction, including semantic similarities of proteins, dynamic selection of prediction domains, iterative function predictions and so on which are advanced and interesting in this area.
