(9-28-16) Prof. Seung-Hwan Lee published the following articles, the second of which was co-authored by Prof. Jeungbo Shim from University of Colorado, Denver.
"On the Estimators and Tests for the Semiparametric Hazards Regression Model."Lifetime Data Analysis, 22, 531-546 (2016).

(9-26-16) Today the department held our first brown-bag lunch of the year. A presentation was
given by four alums who all happen to be employed as actuaries at Allstate: Ashley Borchardt '09, Scott Klepetka '13, Derek England '15, and Christine Peterson '16. The four also spent the day talking with current students interested in becoming
actuaries, as well as participating in an internship fair held on campus.
(6-16-16) The first ever workshop on the Riordan group, held at IWU, is nearing its conclusion
this week. The workshop is being conducted by Prof. Lou Shapiro (Howard University) with Prof. Tian-Xiao He (IWU). Nine students are participating and enjoying every minute of it.
The workshop will be followed by the 3rd International Symposium on Riordan Arrays and Related Topics (RART), held on IWUs campus. This symposium will bring together researchers from
all over the world to discuss current research topics surrounding Riordan arrays.
Many IWU students will have the chance to participate in the symposium through presenting
their research results, attending talks, and conversing with some of the leading mathematicians
in the field.
(3-25-16) Our third brown-bag lunch of the semester was held today. Tung Nguyen '15 took a break from his graduate studies in mathematics at UW-Madison to talk about
all aspects of applying for, and being a graduate student in math.
(3-10-16) The first two brown-bag lunches of the semester have occurred over the last three
weeks. We had the following two excellent talks.
Math Education Panel Discussion: Becoming a Mathematics Teacher. Panelists: Gina Mayer '16 (secondary math ed.), Lauren McAnally '16 (elementary ed.), Alex Burnside '16 (elementary ed.), Angela Herrmann '16 (elementary ed.), and Annie Oliveri '16 (elementary ed.).
Mathematica. Speaker: IWU's Associate Director of Prospect Research, Management, and Analytics, Michael Morrison '03.
