David is a life-long ocean lover. His work experience covers numerous sectors within the Blue Economy, including: defense, ocean observation, and offshore energy. As a professional merchant mariner, David served as a front-line engineer manager overseeing operation and maintenance of propulsion and power plants aboard large merchant vessels and was fortunate to have sailed through every ocean and visited every continent by ship. Later, while working at a marine technology startup, David operated and piloted a fleet of semi-autonomous wave-powered robots that revolutionized oceanographic data collection. Currently, he supports the U.S. Department of Energy’s Water Power Technologies Office on marine renewable energy research and development in collaboration with startups, national labs, and academia.

David is a strong advocate for ocean (technology) literacy and writes frequently on marine technology and other issues relating to the Blue Economy. His writing has been featured on Axios News, The Maritime Executive, SEVENSEAS, the MIT Energy Club, Ocean Exchange, The Economist World Ocean Initiative, and the International Energy Agency Ocean Energy Systems.
