David Ho (oceanographer)

David T. Ho is an American scientist who works as a Professor at the University of Hawaiʻi at Mānoa. He is known for his work on air-sea gas transfer, mangrove carbon cycling, tracer oceanography, and ocean-based carbon dioxide removal (CDR). He is often quoted in the media on CDR and climate change,  and was recommended by the New York Times as a climate scientist to follow on social media.

Ho also created the Bamboo Bike Project, with John Mutter in 2006, which has spurred growth in the number of groups and companies creating bamboo bicycles around the world.

Background
David Ho obtained his A.B., M.A., and M.Phil, all from Columbia University, and was awarded a Ph.D. in Earth and Environmental Sciences from Columbia University in New York in 2001. After a short postdoc at Princeton University, he returned to the Lamont–Doherty Earth Observatory (LDEO) of Columbia University and continued his research there until 2008, when he moved to the University of Hawaii at Manoa. Ho was also Chief Scientist on the Southern Ocean Gas Exchange Experiment, a multi-agency funded effort to study air-sea gas exchange in the Southern Ocean. He has published over 60 research papers.

In addition to being a professor at University of Hawaiʻi at Mānoa, Ho is also an Adjunct Senior Research Scientist in Geochemistry at Columbia University, an invited professor in the Department of Geosciences at the École normale supérieure, and co-founder and Director of Science at [C]Worthy, a non-profit working on building the tools needed to ensure safe, effective ocean-based CDR.

Bamboo Bike Project
Ho started the Bamboo Bike Project together with earth science professor John Mutter, and bicycle maker Craig Calfee. They brought simple, low-cost bicycle designs primarily made of bamboo to Ghana, teaching local craftsmen to build them. The aim was to contribute to poverty reduction by facilitating locally made affordable transportation. They planned to implement the project in African Millennium Villages, as part of the UN Millennium Development Goals. In 2007 he received seed funding for the project from Columbia's Earth Institute.
