Marine Biodiversity Research Group (MBRG) was established in 1995 to carry out a project on recruitment in the Gulf of Thailand supported by the Thailand Research Fund (TRF). At the present MBRG works on various aspects of marine biology particularly coral reef conservation. MBRG/RU also coordinates with various academic institute such as Aquatic Resource Institute, Department of marine science Chulalongkorn University and Department of Biology, University of the Ryukyus, Japan. MBRG is one of academic institute in Ramkhamhaeng University (RU). RU have two main campuses in Bangkok, 21 campuses around the country and 21 examination centers in Europe, America, Asia and Australia

MBRG aim to generate scientific knowledge in marine biology which focus on coral reef biology and to provide academic services and information relating to aspects of marine biodiversity and management as well as environmental conservation.

Research Topics includes:

• Ecology of Coral reef in The Gulf of Thailand.
• Reproduction and Recruitment of Juvenile corals
• Rehabilitation and Management of Coral reefs.
• Reproductive Biology and ecology of soft corals, sponges and zooanthids.
• Population ecology of sea urchin
• Bio-erosion of coral reefs
• Coral bleaching.
• Heavy metal accumulation in coral reefs and sandy beach ecosystem.
• Ecology of sandy beach

MBRG/RU is the focal point for Mu Koh Chang coral reef demonstration site under UNEP/GEF Project on Reversing Environmental Degradation Trends in the South China Sea and Gulf of Thailand. Many activities have been implemented to conserve coral reefs such as

• Public awareness and education
• Networking among agencies
• Sustainable tourism development
• Capacity building
• Sustainable livelihoods
• Improvement of site management to support coral reef rehabilitation

Other main projects implemented by MBRG/RU

• Natural resource damage assessment with special reference to oil spills.
• Initial environmental examination of underwater cable installation.
• Establishing snorkeling trails in Krabi and Phuket Provinces, Andaman Sea.
• Installation of special designed artificial reefs for recreational diving in Krabi and Phuket Provinces, Andaman Sea.
• Development of appropriate techniques and methodologies in coral reef rehabilitation for sustainable tourism in Krabi Trang and Satun Province.
