Hilly Ann Maria Roa Quiaoit is a staunch conservationist, environmental advocate and professor, who is known internationally as the “mother of giant clams.” She is currently doing free-lance consultancy and independent research and development works on ecosystems-based approach to restoration and multi-sectoral approach to environmental governance.

Her efforts in culturing, producing and reseeding clams all over the Philippines have prevented extinction of these organisms. To date, natural recruitment of these endangered shelled giants have been successful. Working for the Center for Tropical Ecology in Germany, she carried out scientific research on the ecology, reproduction and mass production potential of Red Sea giant clams. She has also made significant contributions to global biodiversity with the discovery of new species of giant clam (Tridacna costata Roa-Quiaoit et al, 2008,Tridacnidae) found so far only in the Red Sea. In 2007, she was awarded as one of “The Outstanding Women in the Nation’s Service (TOWNS)” by the President of the Philippines for her exemplary contribution to environmental conservation.
