Professor Dix received his Ph.D. from University of Cincinnati in 1984. Currently, he studies delay differential equations: Oscillation and asymptotic behavior of solutions. He also studies hyperbolic equations in non-cylindrical domains: Solutions to Krichhof-Carrier equations that include non-linear terms and takes into account strings with moving ends.

As a library liaison person, I welcome suggestions for materials that the Alkek library should buy. Please send me the title, author, publisher, ISBN, etc., and I will forward your request to the librarian.
As a Co-Managing editor of the Electronic Journal of Differential Equations, I encourage you to visit the EJDE web page, and to send comments and suggestions.
