NSDL was established in 2006 at UCLA. Dr Xiao Hu is moving to UCSF School of Nursing to start a new phase of his career at the end 08/2013. He will continue to collaborate with the clinical investigators of the NSDL who remain at UCLA to develop, assess, and deploy translational biomedical informatics algorithms and software systems to support the realization of precision medicine.
