UE, WNIN Receive National Edward R. Murrow Award
Posted: August 17, 2021
On Tuesday, August 17, the Radio Television Digital News Association announced the University of Evansville (UE) and WNIN as a national winner for the 2021 Edward R. Murrow Awards.
In 2020, WNIN, the Center for Innovation and Change at the University of Evansville, and ¿Qué Pasa, Midwest? collaborated on a seven-month research and reporting project to find stories of the coronavirus pandemic in seven Midwestern states. COVID Between the Coasts (CBC) is ongoing, adding data-driven reporting on the pandemic for the historical record.
CBC Lead Reporter Sarah Kuper said, “The students' hard work and valuable points of view, combined with the expertise of Dr. Tamara Wandel and Dr. Darrin Weber, made COVID Between the Coasts a historic time capsule of Midwestern life during the pandemic. It was their contribution that put us in the position to win one of the highest honors in the field of journalism. I know I personally learned a lot by working with them.”
WNIN Vice President of Radio Steve Burger said, “Because of the UE data and research, we were able to focus our coverage within a large survey area and break new ground. For example, our ¿Qué Pasa, Midwest? team on the ground in Chicago did valuable reporting on inconsistencies in the national data regarding essential workers. We reported on rural Midwestern communities that previously were not part of the national discussion of the pandemic. We showed the differences in the pandemic’s impact across our survey area.”
“UE is proud to have been part of telling the story of our Midwestern region in the first pandemic in 100 years and highlights the significant contributions that our faculty, staff, and students make every day in our ever-changing world,” said UE President Christopher M. Pietruszkiewicz. “With UE and WNIN working together, we were able to make a difference in a way that we would not have been able to do individually and are delighted by the collaboration.
Since 1971, the Radio Television Digital News Association has honored outstanding achievements in electronic journalism with the annual Edward R. Murrow Awards. These awards are among the most prestigious in broadcast news, and recipients demonstrate the spirit of excellence that Murrow set as a standard for the profession of electronic journalism. Winners will be honored at the Murrow Awards Gala in New York City on October 27, 2021.
University of Evansville Students Earn Prestigious Edward R. Murrow Awards
Posted: June 11, 2021
A group of University of Evansville (UE) students have been recognized for their work on a community journalism initiative that examines the impact of the COVID-19 pandemic on the Midwest.
The UE ChangeLab project, “COVID Between the Coasts,” is a collaboration between two University courses and National Public Radio member station WNIN.
The project, presented in a podcast format, examined seven Midwestern states through the lens of underrepresented populations grappling with the ongoing pandemic.
Over seven months, Aces led by Drs. Tamara Wandel (communications) and Darrin Weber (mathematics) carried out research, conducted interviews, and compiled data to tell localized and human stories.
“The research and reporting for our podcast is broader and richer as a result of the ChangeLab students’ award-winning work,” said WNIN reporter and producer Sarah Kuper.
“COVID Between the Coasts” earned the Excellence and Innovation and Excellence in Writing in the Region 7 group at the 2021 Edward R. Murrow Awards. Since 1971, the Radio Television Digital News Association has honored outstanding achievements in electronic journalism with annual ceremonies.
“These are some of the most prestigious journalism awards out there, and I’m so proud of our students for their work on this project,” Wandel said.
“My classmates and I were able to do everything from research to interviewing and script writing,” UE student Nicole Tucker. “These were all things that we didn’t have a lot of experience in but with the help of our professors and WNIN, we were able to create a successful podcast series.”
A compilation of “COVID Between the Coasts” is available online.
ChangeLabs at the University of Evansville are semester-long courses in which students create positive change for businesses, nonprofits, and the community. Guided by expert coaches, multidisciplinary student teams provide services or develop innovative solutions to challenges. In addition to the award-winning “COVID Between the Coasts” collaboration, other ChangeLab projects include a city-wide bike sharing program and a $90,000 solar panel grant for a local community center.

UE Math Partners with EdjAnalytics to Launch Data Science Academy for High School Students
Posted: March 7, 2019
The University of Evansville’s Department of Mathematics is partnering with EdjAnalytics, a Louisville-based data science firm, to launch the UE Data Science Academy Powered by EdjAnalytics, a week-long program for high school students. The program will run from July 7 - 13, 2019, and will take place on UE’s campus.
“We are proud to support this important initiative with the University of Evansville. At EdjAnalytics, we use data science to improve the world through better decision making. We can’t think of a more valuable way to honor our mission than to support the data science industry’s next generation,” said Susan Olson, PhD, EdjAnalytics COO and UE alumna.
In the Academy, students will learn the basics of data science through a variety of activities. Participants will work with UE mathematics professors and undergraduate students and connect with peers who share an interest in mathematics. Students will attend classes, engage in hands-on projects, and learn to present material and develop interactive apps.
“The digital revolution has created vast quantities of data,” said Darrin Weber, PhD, UE assistant professor of mathematics. “Extracting insights from this avalanche of information is the goal of data science. It has applications to internet search, advanced image recognition, video game development, actuarial science, medicine, sports, recommender systems, genomics, neuroscience, particle physics, and so much more.”
Students currently in grades 9, 10, or 11 who have completed algebra are invited to apply to the academy. The fee is $600 for the overnight, residential option or $350 for the day option. Registration ends May 1, 2019. Space is limited, so early application is encouraged. For more information or to apply, visit www.evansville.edu/data-science-academy.
“The Data Science Academy is a great way for high school students to become familiar with the field of statistics and data science and with its methods and requirements. This preparation is important, because data science plays a critical role in a broad range of academic disciplines, from the natural and social sciences to medicine and marketing. Participants will be especially well-prepared for UE’s Statistics and Data Science degree program,” said David Dwyer, PhD, UE department chair for mathematics. “The University greatly appreciates the generosity of EdjAnalytics, and we are excited to join with them to offer this experience to high school students.”

UE Launches New Actuarial Science Degree Program
Posted: November 19, 2018
The Department of Mathematics at the University of Evansville has launched a new bachelor’s degree in actuarial science. The program prepares students for a career as an actuary, a top-ranked profession offering high salaries in a low-stress environment. In addition to specialized courses focused on actuarial science, the program includes course work in mathematics, statistics and data science, computer science, economics, finance, and accounting. Students may enroll in the program beginning in Fall 2019.
“Actuaries are experts at modeling and managing risk,” said Mark Gruenwald, PhD, professor of mathematics and director of actuarial science. “They are highly trained professionals with strong analytical skills and specialized knowledge of math, statistics, and business. Their work provides financial security for insurance companies, multinational corporations, and the government. Not surprisingly, there is a growing demand for individuals with this rare combination of talent and expertise.”
Advancement as an actuary depends on progress in completing a series of challenging exams, the first one to three of which are typically taken before graduation. The new program provides preparation for five of the 10 actuarial exams required to achieve the highest status within the profession, Fellow of the Society of Actuaries.
The new program was designed in consultation with graduates of the former program and replaces the existing actuarial track within the applied mathematics program.
“We are proud of the successes of our graduates,” said David Dwyer, PhD, chair of the mathematics department. “Our alumni can be found at the highest levels of the actuarial profession in insurance companies and consulting firms across the country and even abroad. Their input was instrumental in helping us to design a first-class program to prepare our students for the changing demands of the actuarial profession. The changes to our program were so significant that we created an entirely new degree dedicated to actuarial science.”
The new actuarial program adds an advanced course in long-term actuarial modeling along with three new required classes in data science.
“Our alumni tell us that actuaries are increasingly exploiting cutting-edge techniques from the field of data science. One example is machine learning, a form of artificial intelligence,” said Gruenwald. “A few years ago, we established one of the few undergraduate programs in data science. Now we can leverage our data science courses to better serve our actuarial students. In fact, we will encourage all actuarial science majors to complete a minor in statistics and data science, and we anticipate that some will choose to complete a double major in actuarial science and statistics and data science.”
The new program provides course work that exceeds the stated requirements of the Society of Actuaries (SOA) for achieving Advanced Curriculum status.
For more information, to enroll in the actuarial or statistics and data science programs at UE, or to arrange a personal visit with professors Dwyer or Gruenwald, contact the Office of Admission at 833-BeAnAce or email firstname.lastname@example.org.

Azarian publishes research paper
Posted: July 10, 2018
Mohammad K. Azarian, professor of mathematics, published a paper entitled, Risala al-watar wa'l jaib ("The Treatise on the Chord and Sine")-Revisited, in Forum Geometricorum. The purpose of this paper was three-fold. First, Azarian used Jamshid al-Kashi's [Kashani's] famous cubic equation and a mathematica program to calculate sine of one degree to over 11,200,000 decimal digits of accuracy; an amazing improvement over the 17 digits of accuracy that Kashani found by pencil and paper in 1426. Then, Azarian conjectured that Kashani's cubic equation can be used to calculate sine of one degree to any desired accuracy. Second, Azarian set the record straight about the number of correct digits obtained by Kashani that were reported in many previous studies. Third, Azarian commented on some statements that he made in his previous paper on this topic.

This work focuses on YouTube comments from the top two hundred trending videos as a source of user text data. Previous Sentiment Analysis Models focus on using hand-labelled data or predetermined lexicons. The goal is to train a model to label comment sentiment with emoticons by training on other user-generated comments containing emoticons. Naive Bayes and Recurrent Neural Network models are both investigated and implemented in this study, and the validation accuracies for Naive Bayes model and Recurrent Neural Network model are found to be .548 and .812.
Azarian publishes reviews of research papers
Posted: March 14, 2018
Mohammad K. Azarian, professor of mathematics, published reviews of two research papers in the American Mathematical Society's Mathematical Reviews (MathSciNet), the authoritative gateway to the scholarly literature of mathematics.
The first paper, by Tamás Lengyel and Diego Marques, entitled " The 2-Order of Some Generalized Fibonacci Numbers," was published in Integers 17 (2017). In this paper the authors fully characterize the 2-adic valuations of the generalized Fibonacci sequence of order 4. They also partially characterize the 2-adic valuations of the generalized Fibonacci sequence of order 5.
The second paper, by Yildiz Aydin and Ali Pancar, entitled "Frattini Supplements and Frat Series", appeared in the Bulletin of the Iranian Mathematical Society 43 (2017). The authors have shown that finite abelian groups are Frattini supplemented, and every conjugate of a Frattini supplement of a subgroup is also a Frattini supplement. Also, they have obtained new characterization of primitivity of groups in terms of Frattini supplemented groups.
Moreover, Azarian accepted the invitation to serve on the editorial board of The Iranian Journal of Mathematical Sciences and Informatics.
Weber publishes paper on mathematical research
Posted: January 23, 2018
Darrin Weber, assistant professor of mathematics, has published a paper in the International Electronic Journal of Algebra. The paper is titled "The Zero-Divisor Graph of a Commutative Ring without Identity" and can be found at http://ieja.net/files/papers/volume-23/11-V23-2018.pdf.
It is a joint work with David F. Anderson (University of Tennessee).
A ring is a mathematical structure where you can add, subtract, and multiply, but not necessarily divide (think of the integers). A zero-divisor is an element in a ring that multiplies to another element to give you 0. Zero-divisors do not have a lot of structure, so we place them in a graph and see what the graphical structure can tell us about the ring structure. This paper furthers that endeavor by looking at a new class of rings.

Department of Mathematics at UE Announces New Statistics and Data Science Program
Posted: May 6, 2016
The Department of Mathematics at the University of Evansville has announced the creation of a degree program in Statistics and Data Science. Students in the program will apply statistical and computational techniques to convert vast amounts of data into actionable insights that drive decision making. Students may enroll now, and classes are set to begin in the fall of 2016.
The digital revolution has created vast amounts of data. Extracting meaning from this avalanche of information is the goal of data science, a rapidly growing field that is revolutionizing marketing, education, and sports, as well as scientific fields such as genomics, neuroscience, and particle physics.
There is currently a global data scientist talent gap. It is estimated that by 2018, there will be twice as many data scientist jobs as there are data scientists.
“Individuals with education and experience in data science are in high demand,” says Shane Davidson, vice president for enrollment services at UE. “Right now, the average salary for a data scientist is $118,000.”
Extracting meaning from data requires not only quantitative skills such as mathematics, statistics and computer programming, but also experience in working with real-world data.
“The curriculum for the new program is grounded in classical statistical techniques while incorporating cutting-edge techniques and tools for dealing with Big Data,” says Dave Dwyer, chair of the mathematics department at UE. “The courses are all project-driven, so students gain experience in working with real-world data not only through their internship experiences, but also through their course work.”
For more information or to enroll in the Statistics and Data Sciences program at the University of Evansville, contact the Office of Admission at 812-488-2468 or visit www.evansville.edu/majors/math/dataScience.cfm.

UE Professors Awarded Grant for Science, Math Scholarships
Posted: September 23, 2013
University of Evansville faculty members Joyce Stamm, associate professor of biology, and Adam Salminen, associate professor of mathematics, have secured a five-year, $610,600 grant through the National Science Foundation’s S-STEM (Scholarships in Science, Technology, Engineering, and Mathematics) program to assist students in science and mathematics. The grant is one of about 90 awarded from the 436 proposals submitted to the S-STEM program, and is the largest faculty grant in school history.
The award provides funds for financial, academic, and professional support for students majoring in the sciences and mathematics. The majority of the grant, around $528,000, will fund the new UE Science and Math Scholarship (SAMS), which will provide four-year scholarships to approximately 34 academically talented students with financial need who are majoring in biochemistry, biology, chemistry, environmental science, mathematics, or physics.
The grant also provides funds for new support services for science and mathematics majors at UE. These services include an introductory summer course for incoming students, a semester-long course on study skills and time management, monthly career colloquiums, and a science and math-themed living-learning community in a campus residence hall. These activities will be available to all math and science students at UE and will continue after the grant ends in 2018.
“This grant not only represents an incredible opportunity to transform the lives of future students at the University of Evansville, but the National Science Foundation’s decision to fund the proposal also demonstrates the University’s outstanding track record of preparing students to succeed in math and science careers and graduate programs,” said John Mosbo, UE senior vice president for academic affairs. “At UE, students receive a personalized education that equips them to make an impact on the national shortfall of qualified STEM professionals. Dr. Salminen and Dr. Stamm’s successful grant application affirms that commitment to teaching.”
“Thanks to this grant, we’ll be able to help an even greater number of high-achieving students pursue an education at the University of Evansville,” said Salminen. “We expect that the SAMS scholarship will increase enrollment of students majoring in math and the sciences.”
“The new student success initiatives will also help ease students’ transitions from high school to college, and from college to graduate school or the workforce,” Stamm added. “We believe this level of personal support will increase retention of students in math and science majors, and ultimately increase the number of qualified professionals in the STEM workforce.”
SAMS scholarships will be available starting with UE’s entering freshman class of 2014. For selection criteria and application details, interested students may visit the program website.
UE Names 2013 Berger Award Winners
Posted: August 20, 2013
David Dwyer, Mark Gruenwald, and Jean Beckman have been named the winners of the 2013 Sydney and Sadelle Berger Awards, presented each year to members of the University of Evansville faculty who demonstrate exceptional scholarly activity and service.
Dwyer, chair of the Department of Mathematics and a professor of mathematics, and Gruenwald, also a professor of mathematics, jointly received the award for scholarship. Beckman, a professor of chemistry, earned the award for service. UE President Tom Kazee presented both awards today at the University’s annual Fall Conference for faculty and administrators.
As a team, Dwyer and Gruenwald have made a profound impact on their academic discipline nationwide. They recently received a highly competitive $600,000 grant from the National Science Foundation that will allow them to broaden and continue their Resequencing Calculus project, which builds on work funded by a previous NSF grant in 2009.
For this project, Dwyer and Gruenwald revised the standard three-semester calculus sequence to better meet the needs of students in a variety of STEM disciplines. They also wrote a 700-page textbook to support the first two semesters of this sequence, piloted the sequence at UE, and identified supporters of the redesigned sequence at other institutions.
Dwyer and Gruenwald, both of whom have won the Dean’s Teaching Award for UE’s College of Arts and Sciences, have also sold more than 30,000 copies of five commercially published mathematics textbooks.
Beckman, who won the award for service, came to the University of Evansville 35 years ago. Since then, she has become widely respected on campus for her fairness, her selfless dedication to the University, and her passion and commitment to teaching.
Beckman chaired the Department of Chemistry from 1989 to 2003. Although her first love is teaching, she has also served the University in numerous administrative roles over the years, including terms as dean and interim dean of the College of Arts and Sciences and interim vice president for academic affairs.
Beckman has served on countless University committees: search committees, numerous Faculty Senate committees, the General Education Revision Subcommittee, the Writing Subcommittee, the Honorary Degree Committee, and the UE United Way Campaign Committee, just to name a few.
The Berger Awards are presented annually in memory of Sadelle and Sydney Berger. Sadelle was a UE graduate and lifelong member of the Academy of Arts and Sciences at UE, while Sydney was a well-known local attorney. Both dedicated their lives to public service. The Berger family established the endowment to give recognition to faculty at the University of Evansville.
UE Math Professors Awarded $600,000 National Science Foundation Grant
Posted: October 10, 2012
Dave Dwyer and Mark Gruenwald, professors of mathematics at the University of Evansville, have been awarded a three-year, $600,000 grant from the National Science Foundation.
The grant is one of 30 awarded out of over 400 proposals submitted to the NSF’s TUES program (Transforming Undergraduate Education in Science, Technology, Engineering and Mathematics) for extending and broadening the work of successful pilot projects related to undergraduate STEM education. It is one of only two such grants awarded for projects related to mathematics.
“This grant is not just a tremendous honor for Dr. Dwyer, Dr. Gruenwald, and the Department of Mathematics, but it is also a wonderful example of the quality of the faculty at the University of Evansville,” said UE President Thomas A. Kazee. “Their project has the potential to revolutionize the way calculus is taught across the nation. By funding this grant, the National Science Foundation affirms the remarkable commitment Professor Dwyer and Professor Gruenwald have made to scholarship and teaching.”
The grant supports the second phase of Dwyer and Gruenwald’s Resequencing Calculus project, which builds on work that was funded by a $150,000 NSF grant awarded in 2009. Under the first grant, Dwyer and Gruenwald revised the standard three-semester calculus sequence to better meet the emerging needs of students in a variety of STEM disciplines, wrote a 700-page textbook to support the first two semesters of this sequence, piloted the sequence at UE, and identified supporters of the redesigned sequence at other institutions.
Phase 2 of the project entails completing the three-semester textbook, testing and assessing the textbook and the sequence at four other universities (Valparaiso University, Millikin University, the University of Central Missouri, and the University of St. Thomas in Minnesota), and campaigning for broad and sustained adoption of the revised sequence.
“A close look at the order and choice of topics in the mainstream calculus sequence is long overdue, especially in light of the ever-increasing role of mathematical and statistical modeling in fields such as chemistry, biology, and economics,” said Dwyer. “For too many students and at too many institutions, mainstream calculus sequences as they exist now are a poor fit.”
According to biochemist Kristy Miller, chair of UE’s Department of Chemistry, “Students in chemistry and the life sciences would benefit from exposure to certain topics that are usually not covered until the third semester of calculus, but most of these students do not have room in their schedules for a full three-semester sequence.”
“One of the goals of the Resequencing Calculus project is to rearrange the ordering and choice of topics in the mainstream calculus sequence to better fit the needs of today’s students,” Gruenwald added. “Our approach more closely connects calculus instruction with its application in STEM fields, and it facilitates deeper and earlier exposure to both upper-level math courses and upper-level courses in STEM disciplines where calculus is applied.”
A number of UE faculty members will serve in an advisory capacity to the project, including Mohammad Azarian, Erin Davis, Clark Kimberling, and Adam Salminen in the Department of Mathematics; Jeff Braun in the Department of Physics; and David Unger in the Department of Mechanical and Civil Engineering. Brian Ernsting, assistant dean of the College of Arts and Sciences, will serve as an internal assessment advisor. Teams of undergraduate math majors at UE will contribute to the development of the text and related materials.
Dwyer and Gruenwald will also be assisted by faculty and students at each of the pilot institutions, an external professional assessment team, and an advisory board consisting of national leaders in various STEM professional organizations.
