    Chaojiao is a research scientist at CSIRO's Oceans and Atmosphere Flagship. She was awarded a PhD in physical oceanography by Oregon State University in 1997. She worked on coupled data assimilation with an intermediate coupled atmosphere-ocean model during her postdoctoral at UCLA. In 2000, she joined the Hydrological Sciences Branch at NASA Goddard Space Flight Centre to work on satellite snow data assimilation. In 2003, she joined the Global Modeling and Assimilation Office at NASA Goddard to work on ocean data assimilation with global ocean circulation models (Poseidon and MOM4). She joined CSIRO in 2008 and has since worked on ocean data assimilation, dynamical downscaling using a high-resolution ocean model, and dredge plume modeling.
