Personal profile


Professor Ezaz’s research focuses on the evolutionary and comparative genomics of sex determining mechanisms and sex chromosome evolution in non traditional vertebrate model species, a discipline primarily devoted to basic research aiming to expand the current knowledge base.

His areas of research interest include development and application of molecular markers, molecular cytogenetics, epigenetic regulation of sex differentiation, plasticity and adaptation. Professor Ezaz uses diverse taxa, ranging from fish to birds, as well as invertebrates including crustaceans and mollusc to answer his research questions.

Professor Ezaz has co-authored papers published in high impact journals including Nature, Science, Current Biology and Molecular Biology and Evolution.

Professor Ezaz’s contributions to his field of expertise have led to a deeper understanding of the mechanisms and evolution of sex determination and sex chromosome evolution, particularly in reptiles. In recognition of his significant contributions he was awarded prestigious ARC Future Fellowship. He holds a very strong track record in the context of his discipline expectations and led the establishment of an international network of cytogeneticists (chromosomics network) which has members form 18 different countries.

Professor Ezaz supervises postgraduate students and also teaches units on Genetics and Genomics and on plants and animals to 2nd and 1st year undergraduates respectively.
