Nathaniel Dean is a Professor in the Department of Mathematics at Texas State University, San Marcos. He received his BS in mathematics and physics from Mississippi State University in 1978, his MS in applied mathematics from Northeastern University in 1983 and finally his Ph.D. in mathematics from Vanderbilt University in 1987. Dr. Dean’s research focuses on constructing mathematical models of complex systems and developing computer tools to visualize, design and analyze such systems. His research includes discrete mathematics, optimization, data mining, and network visualization. He has over 60 publications in these fields, and some of his work is highlighted in the PBS television series *Life by the Numbers*. Dr. Dean has served as Managing Editor of the *Journal of Graph Theory*, co-organized several mathematics conferences, served on the Board of Governors for the Mathematical Association of America (MAA), served as Chair of the Human Resources Advisory Committee (HRAC) for the Mathematical Sciences Research Institute (MSRI), and served as Editor of four volumes for the American Mathematical Society (AMS): *Computational Support for Discrete Mathematics*,* African Americans in Mathematics*, *African Americans in Mathematics II*, and *Robust Communication Networks*. In 1997 he received the President’s Silver Award from Bell Laboratories. Currently, Dr. Dean serves on the Human Resources Board for the American Institute for Mathematics (AIM), and he continues to serve as President of the National Association of Mathematicians (NAM).
