# Irina Nenciu

**Irina Nenciu** is a Romanian citizen and mathematician born in Bucharest, Romania on November 9, 1978.^{[1]} She is an associate professor of mathematics at the University of Illinois at Chicago^{[2]} and has overseen undergraduate and graduate students' research.^{[1]} She is also a researcher for the Institute of Mathematics of the Romanian Academy in Bucharest^{[1]} and researches integrable systems, random matrices, and orthogonal polynomials.^{[1]} She is married to Christof Sparber, who is also a professor of mathematics at the University of Illinois at Chicago.^{[1]}^{[3]}

## Academic career[edit]

Nenciu earned her B.S. in Mathematics from the University of Bucharest, Romania in 2001 under the advising of Professor Viorel Iftimie. Her undergraduate thesis is titled *Semiclassical asymptotics of spectra of second order elliptic differential operators*.^{[1]} Following this, she earned her Ph.D. in Mathematics from the California Institute of Technology in 2005 under the advising of Professor Barry Simon. Her graduate thesis is titled *Lax Pairs for the Ablowitz-Ladik system via orthogonal polynomials on the unit circle*.^{[1]}

Currently Nenciu is an associate professor of mathematics at the University of Illinois at Chicago and a researcher for the Institute of Mathematics of the Romanian Academy in Bucharest.^{[1]} She was previously a member of the Institute of Advanced Study at Princeton in 2006^{[1]} and an instructor at the Courant Institute at New York University from 2005-2008.^{[1]}

## Services in the Math Community[edit]

In her career, Nenciu has served as a member of the University of Illinois senate from 2016-2019.^{[1]} She was also an organizer for the SIAM Conference on Nonlinear Waves and Coherent Structures in Philadelphia on August 8-11, 2016.^{[5]} Nenciu spoke at several international meetings, including the Joint Analysis and Probability Seminar at the University of Wisconsin in 2016^{[6]} and at the 8th Congress of Romanian Mathematics at Iasi, Romania in 2015,^{[7]} as well as the Midwest Women in Mathematics Symposium at the University of Illinois at Chicago in 2013.^{[8]}

## Awards and Honors[edit]

Nenciu won the UIC Teaching Recognition Program award in 2016 for her documented teaching excellence over the course of three years.^{[9]}^{[10]} While in her graduate program at the California Institute of Technology she was awarded three Scott Russell Johnson prizes: for excellence in first year graduate studies in 2002, for excellence in graduate research and teaching in 2004, and for excellence in graduate research and teaching in 2005.^{[11]} From these awards she was also named a Scott Russell Johnson fellow.^{[11]} She has also been awarded four grants from the National Science Foundation for her research work in mathematics from 2007 to 2018.^{[1]}^{[12]}
