Research interests

Dr Tam is internationally recognized for pioneering the application of micromanipulation and embryo culture for analyzing the development of mouse embryos and fate mapping of the mouse germ layers and embryonic gut.

His research focuses on the cellular and molecular mechanisms of body patterning during mouse development. His research includes pioneering the application of micromanipulation and embryo culture for analysing mouse embryos and examining the development of the neural tube and embryonic gut. His other current research is on X-linked diseases.
