David explores new ways of improving human health and wellbeing through the air we breathe, with ramifications to how we eat, and regenerate life on the planet. His scientific research, as well as his inventions, startups, and creative spaces in France and the USA, have led to the discovery of airway hygiene and the new consumer health platform FEND. David was Professor of the Practice of Bioengineering at Harvard University in the School of Engineering & Applied Sciences from 2001 to 2019, and transitioned to Associate in 2019 to lead the startup of FEND, support the startup of the nonprofit Next Breath, and start a new Cambridge-based restaurant with Nadia Michaud, Senses, where the commitment to organic regenerative food parallels the commitment of David’s future-of-food company Incredible Foods. David has received many international honors and awards, is a member of the National Academy of Engineering in the USA and in France, a member of the National Institute of Inventors, and a Chevalier of the Arts & Letters by the French Ministry of Culture.
