Nathaniel Dean is an African-American mathematician and educator who has made contributions to abstract and algorithmic graph theory, as well as data visualization and parallel computing.
Scientific career[]
Dean completed his Ph.D. thesis on graph theory at Vanderbilt University in 1987.[1] For the next eleven years, he worked at the Software Production Research Department of Bell Labs,[2] where he would author over thirty scientific publications on graph theory, graph algorithms, parallel computing, and data visualization.[3] In 1995 he posed a conjecture which led to progress on the second neighborhood problem,[4][5] which remains open as of 2020. His work on using graph theory for data mining was featured in the PBS series Life by the Numbers.[6]
In 1997 Dean received the Bell Labs President's Silver Award,[7] and shortly thereafter began a professorship at Rice University.[2] While at Rice, he supervised four Ph.D. students with thesis topics ranging from algorithmic graph theory to biological computing.[1] On January 11, 2001, Dean was elected Vice President of the National Association of Mathematicians (NAM).[8] In 2003 he moved from Rice University to Texas Southern University, where he attained the rank of full professor and would serve as chair of the mathematics department.[9][2]
Dean's departure from Texas Southern University to Texas State University was announced in a NAM newsletter in 2006.[10] Dean focused on mathematics education and outreach throughout his time at Texas State, most notably by serving as President of NAM from 2005 to 2015.[11][12] His research activities during this time include graph theory and an influential article on data visualization.[3][13] He retired from Texas State in 2016.[14]
Outreach[]
Dean was actively involved in mathematics education and outreach throughout his career. In addition to his involvement in the PBS series Life by the Numbers, he developed software to teach discrete mathematics at the K-12 level.[15] Much of Dean's outreach was through the National Association of Mathematicians (NAM), a nonprofit which aims to promote the mathematical development of underrepresented minorities; his involvement with NAM includes serving as Vice President (2001-2004) and President (2005-2015). Separate from his involvement with NAM, Dean worked with the American Mathematical Society to publish two conference proceeding on African American mathematicians.[16][17] Dean's fifth and final Ph.D. student graduated from Texas State University in 2010, with a thesis on secondary school mathematics pedagogy.[1]
