About EVRI - Company Overview

Barry Wise and Neal Gallagher met in October 1985, the first day of a graduate math class at the University of Washington. They founded Eigenvector Research on January 1, 1995. Both men have broad experience modeling chemical systems using theoretical and empirical approaches.


Wise first developed EVRI’s flagship chemometrics software, PLS_Toolbox, in 1989. More than 20 years later, Eigenvector Research continues to set the standard in powerful data analysis solutions software by providing extremely flexible, comprehensive and easily customizable configurations for use in a wide variety of applications and operating systems.


Software is just one component of Eigenvector’s winning equation. EVRI is well known for no-nonsense, unbiased and efficient consulting. Wise, Gallagher and EVRI staff have 100+ man-years experience with Multivariate Analysis, and have enjoyed the privilege of working with clients globally.
