@     INTRODUCING the EMB group at the University of Hong Kong @

The Evolutionary and Molecular Biology Group (EMB group) is a team of young researchers at the University of Hong Kong, School of Biological Sciences, led by Professor Frederick Chi-Ching Leung. The EMB group works on molecular and evolutionary virology, avian genomics and comparative endocrinology, evolutionary genomics and traditional Chinese medicines. Members of the group are diverse with multi-disciplinary backgrounds, including molecular biologists, computer scientists, mathematicians and physicists..
