The CIELO platform is a program under the new CTSA Program National Center for Data to Health (CD2H). 

CD2H stands for Center for Data to Health. CD2H will be led by Dr. Melissa Haendel (OHSU), Dr. Kristi Holmes (Northwestern University), Dr. Sean Mooney (University of Washington), Dr. Christopher Chute (Johns Hopkins University School of Medicine), and John Wilbanks (Sage Bionetworks). These institutions, together with The Scripps Research Institute, Washington University in St. Louis, the University of Iowa, and The Jackson Laboratory will work with CTSA Program hubs and the National Center for Advancing Translational Sciences (NCATS) at the National Institutes of Health to launch the CD2H.
