I'm a 3rd year Economics PhD student, with experience in development and environmental economics (and public, political, empirical micro econ). I worked for the GWWC research team for a while. If people are interested in support/collaboration on an EA project that could use my skills, get in touch.
As an example, I recently drafted a blog for 80k on "what does economics tell us about replaceability in career choice?" at the request of Ben and Will.
