Program Developers

Development of Mplus started in October 1995 with the first version being released in November 1998, the second version in February 2001, the third version in March 2004, the fourth version in February 2006, the fifth version in November 2007, the sixth version in April 2010 and the seventh version in September of 2012. The development of Mplus has been funded in part with Federal funds from the National Institute on Alcohol Abuse and Alcoholism, National Institutes of Health, in the form of Small Business Innovation Research contracts and grants to the small business Muthén & Muthén.

Besides Linda and Bengt, the current Mplus development team consists of Tihomir Asparouhov and Thuy Nguyen. This team has been together for several years and under its development the capabilities of Mplus have grown dramatically. The other member of the Mplus team is Michelle Conn who has been the Office Manager for the last several years. Over the years, several other programmers have been involved in the development of Mplus including Stephen Du Toit, Shyan Lam, Kerby Shedden, and Damir Spisic.
