Weston J. Wellington, a vice president with Dimensional, is another of the firm's in-house research experts. He works closely with financial advisors in the US, Canada, Europe, Australia, and Latin America, showing them how a science-based "equilibrium" strategy is the most reliable way to achieve investment success and why their clients are unlikely to hear about this approach from the usual sources of financial advice. One of the firm's most engaging speakers, Weston is an accomplished writer as well, with a regular column on Dimensional's password-protected website, Down to the Wire.

Prior to joining Dimensional in 1995, Weston was director of research at LPL Financial Services, Inc. in Boston, and he has accumulated over thirty-five years of experience in the investment industry. He holds a BA in history from Yale University.
