Robert Sevenster (a.k.a. Bob), founder of coralAID, first joined the NHRCP back in 2015 as a conservation student. With a background in electrical engineering and the drive to do good, Bob was searching for ways in which he could apply his technical expertise to help our program better protect, preserve and expand coral reefs. After learning about the research of Professor W.H. Hilbertz and seeing first hand, the benefits and success of electrified artificial reefs here on Koh Tao, Bob set to work creating his own open source Mineral Accretion Devices (MAD).
