Employment: Dr. Eric W. Davis — Physicist, then Chief Science Officer, then Senior Science Advisor (2002-present)

The longest-running affiliation in Davis's career and the only one whose internal promotions can be dated independently: archived captures of EarthTech's own staff pages show him as a physicist by February 2005, Chief Science Officer by November 2017 and still in November 2019, and Senior Science Advisor from around January 2020 — a title the site still carried at the most recent capture in August 2026. Dated captures evidence title CHANGES, which self-description alone cannot manufacture.
