David T. Wang
GRADUATE STUDENT · MIT/WHOI · GEOCHEMISTRY

I'm a Ph.D. candidate in the MIT/WHOI Joint Program and member of the Hardcore Stable Isotope Laboratory at MIT.

research

Presently much of my time goes towards developing isotopes as tracers of groundwaters and hydrocarbons. This research is motivated by applications to resource exploration, carbon cycle characterization, and environmental remediation.
