**List it in both.**

The education section is typically just a list of degrees and dates. It states the official certifications that you have received and can prove with documentation. This should include your field and maybe a focus area, but not much detail. You might also include your dissertation and any other papers in a separate *Publications* section.

Work experience lists all of the jobs and positions you had during that time. This is where you explain in more detail your research, job responsibilities, and professional skills. I would list your *Work Experience* higher than *Education* if you are applying in industry.

Applying for jobs in academia is completely different than industry, and for that I would look for advice from [Academia SE](http://academia.stackexchange.com) on how to properly organize a CV.
