New director appointed to the Center for Theoretical And Observational Cosmology
We are delighted to announce Donghui Jeong as the next Director of the Center for Theoretical And Observational Cosmology. Donghui is a highly regarded member of the international cosmology community, with a very successful and broad research program that extends to all three Centers of the IGC. We look forward to Donghui’s leadership, and the new ideas he will bring to this next phase of the CTOC!
