I am physician scientist active both in basic research and clinical practice. My research interests are to 1) uncover the genetic and epigenetic bases of neurodevelopmental disorders or rare diseases with neurodevelopmental defects; 2) model genetic diseases using human patients derived cellular models and genetic mutant mice; 3) understand the circuit and molecular mechanisms underlying autism spectrum disorder; 4) develop novel molecular and epigenetic targeted therapies for genetic and epigenetic diseases. My clinical expertise is on clinical and biochemical genetics of rare and undiagnosed diseases in children and adult.
