Ishanlosen Odiaua is a registered architect from Nigeria, with a PhD in Art History from the Université de Paris I (Pantheon-Sorbonne). She lectured in architecture in Nigeria for 8 years, and later served as Program Manager for Immovable Heritage at the Centre for Heritage Development in Africa (CHDA) based in Mombasa. She brings to HACSA a wealth of experience in cultural heritage management. This comes from having worked extensively with UNESCO: first as a program specialist and then as a consultant in the implementation of the 1972 World Heritage Convention. Her work with UNESCO included the preparation of the Second Periodic Report for Africa; organizing a Conference on Safeguarding African World Heritage as a driver of sustainable development, which resulted in the Ngorongoro Declaration in 2016, organizing the UNESCO-Africa-China Forum on World Heritage Capacity Building and Cooperation in 2019, and serving as an expert on critical sites, most particularly Lamu in Kenya, Togo and Benin. She has also consulted with ICOMOS, ICCROM, the African World Heritage Fund (AWHF), the World Monument Fund, the World Bank and the African Development Bank.

Since February 2019, and on a pro bono basis, she has been leading the preparation of the Third Periodic Report on the Implementation of the World Heritage Convention in Africa, under the aegis of the African World Heritage Fund (AWHF). She is currently Vice-President of ICOMOS-Nigeria.
