Romain Lacombe

I'm an AI researcher, entrepreneur, and technology investor working on human and planetary health.

Publications

I am currently conducting research in AI for Science at Stanford. My areas of interest span physical scales, from weather and climate science to materials discovery and molecular biology. Latest work:

About me

Previous work

• I co-founded Plume Labs, an air quality company building microsensors and AI models to map and forecast air pollution. Plume Labs was acquired by AccuWeather to become its center for AI for climate, which I led in 2022-2023.
• I'm a TED Fellow and introduced our work on air quality in this talk at TED 2018.
• From 2011 to 2014 I launched data.gouv.fr to open government data in my native France.

Technology investing

• I am a deeptech angel investor and a venture partner at early stage fund HCVC.
• I back early stage frontier technologies for human and planetary health, across clean energy (fusion, storage, DER) and biosciences (drug discovery, gene editing, wetlab automation).
• My worldview: chemistry rules everything around us. I'm most excited about how progress in AI accelerates scientific discovery in the world of cells, molecules, and materials.

About me

• I studied physics and applied math at Ecole Polytechnique, engineering systems at MIT, and chemical engineering at Stanford.
• I like to run, bike, swim, and enjoy nature surrounded by cholrophyll and Rayleigh scattering!
