Mathematics Department Newsletter


March 2002


This should be a fairly newsy newsletter this year.  Since you last heard from us, we have had a number of notable retirements, we have hired many new faculty members, and we regret to report the passing of Brother Joseph W. Stander.

Brother Joe passed away in February 2001 following a long illness.  An obituary for Brother Joe appears in this letter.  I will add that working with Brother Joe has been an honor.  He served as Provost of this university from 1974-1989; I think he is best remembered for supporting faculty initiatives that supported student initiatives.  The Stander Symposium honors Brother Stander and provides an annual forum to celebrate undergraduate research.  It is an exciting two day event every March.  Following Brother’s passing, faculty members in the Department of Mathematics donated funds which were then matched by the department.  These funds were then matched by the Office of the Provost and again by the Honors Program.  These funds will be used to recognize excellence at the Stander Symposium. 

Tom Gantner, John McCloskey, Carroll Schleppi and Ralph Steinlage retired on June 30, 2001.  135 plus years of outstanding service is represented in that previous sentence.  Citations for each will appear in the newsletter, but again, I will add some comments.  This has been a stable department for many years.  Much of that stability is represented in these folks.  It has been a real honor working with Tom, Jack, Carroll and Ralph.  We wish each of them well with their new pursuits; they all drop in often enough with big smiles on their faces to let us know that they are doing just fine.  We are faced with an unenviable task; how do we replace these folks?

To begin to answer that question, we were very active and we were outrageously successful on the hiring trail last year.  We hired five people, Stephanie Edwards, Peter Hovey, Rebecca Krakowski, Darren Parker and Qin Sheng, into tenure track positions.  Short biographies for each person will appear in the newsletter.  Several years ago, anticipating the rapid turnover in the department, a vision subcommittee of the department analyzed our role at the University of Dayton.  In response to the analysis, the subcommittee constructed a vision statement and a hiring plan.  It is a good thing.  We currently have nine faculty members with less than four years experience at the University of Dayton.  In our vision, we recognize the responsibility to deliver a strong major; several of the new

faculty focus on the traditional core areas of mathematics.  Our students will continue to gain admittance to top Ph.D. granting institutions.  We also recognize that the number of majors is small.  In our vision, we continue and strengthen our connections with the applied and professional programs across the campus and in the community.  We have recently hired two statisticians, a specialist in mathematics education, a computationalist, and a combinatorialist.

Transition on campus continues, but in fact this year has been a year of waiting and expectation instead of a year of transition.  We have been awaiting the announcement of the new president.  On February 18, the board of trustees and the Marianists appointed Daniel J. Curran, executive vice president and vice president for academic affairs at Saint Joseph’s University, as UD’s 18th president.  For more details, try the web site,  We also await the ground breaking for the building and renovation project in the science complex (Sherman and Wohlleben Halls).  With the renovation will come the dedicated Schraut Memorial Lecture Hall, and so we await.  If you want to keep up with details related to the new construction, try the web site,  Next year should be a year of transition; I anticipate next year’s Message From The Chair will inform you of many of these upcoming transitions.

Next year we intend to organize the 20th Biennial Seminar.  The seminar is not the same without Professor Schraut.  We are looking for ideas to regenerate excitement and enthusiasm in the seminar.  If you have any ideas, please contact me at  And please feel free to contact me with ideas beyond the scope of the seminar.

Please contact me if you see anything misreported in this newsletter.  The letter is on our departmental website and so, misprints will be corrected.  In an effort to use our financial and material resources wisely, we intend, in the future, to distribute the newsletter electronically.  Please share with us your email address.   Visit the web site,, to see the online version of the newsletter.

Thanks. Paul Eloe



Thank you for your generous support.  In the past we have relied heavily on your support so we can compete technologically.  This has been no small task as technology challenges mathematics education.  Clearly computation and quantification is a part of the whole of mathematics.  A common perception with which we contend is that mathematics is computation.  For example, your support gives us the flexibility this year to initiate an endeavor in support of the School of Business Administration (SBA).  Beginning in the Fall term, 2002, all incoming SBA students are required to use laptop computers.  This policy goes campus wide beginning with the Fall term, 2003.  Gerry Shaughnessy and Stephanie Edwards will deliver MTH 128, Finite Mathematics, and 129, Calculus for Business, respectively, to groups of first year SBA students in a laptop environment.  The motivation is that SBA students are learning their mathematics in a professional environment.  The challenge for us is to maintain the integrity of the mathematics.  In other endeavors, we continue to develop our online instruction capabilities as well as online tutorial abilities.  With your support we continue to extend our efforts and stay competitive.

The Second Kenneth C. Schraut Memorial Lecture

On September 21, 2001, Dr. Richard Schoen (72) delivered the second Kenneth C. Schraut Memorial Lecture entitled Geometry in Two and Three Dimensions.  The abstract can be found at  Rick was the recipient of this year’s University of Dayton Distinguished Alumnus Award and he received the award at the Alumni Association Awards Dinner during the evening of Friday, September 21.  He spent the day in the Department of Mathematics and we had great fun.  He lunched with our current majors, Christopher Bomba, Michelle Franz and Julia Tosi.  Chikako Mese (91) flew in to join the luncheon and the day’s festivities.  Chikako studied with Rick and earned her Ph.D. at Stanford.  She is now on the faculty at Connecticut College.  Marilyn Schraut Szorc, and her son Greg, joined us for the festivities.  Greg is a senior in high school and he is interested in biomedical engineering.  The Szorc’s took this opportunity to take a recruiting visit to UD and participate in the Memorial Lecture.  We enjoyed seeing Al Berens (55), Hal Schoen (63), Jim Schoen (67), Dan Voss (79), and Joe Huelsman (98).  Rick spoke to a truly diverse audience that day consisting of experts, non-experts, faculty, students, friends and family.

On a sobering note, September 21 follows September 11, 2001 quite closely.  There was still considerable emotion and uneasiness.  Travel was not easy.  Rick, we will always remember and appreciate that you never wavered and kept your commitment to deliver the second Kenneth C. Schraut Memorial Lecture.  Thanks.

Stephanie Edwards, Ph.D. 1998, University of Wisconsin, Madison, complex variables.  Stephanie has three years experience as an assistant professor at Bemidji State University in northern Minnesota before coming to UD.  She sometimes complains of the heat but she has yet to complain of the mosquitoes.


Pete Hovey, (75) Ph.D. 1980, University of Kentucky, statistics.  Pete has worked as a statistician for UDRI for many years and has three years teaching experience at AFIT.  Welcome home Pete.


Becky Krakowski, Ph.D. 2000, North Carolina State University, mathematics education.  Becky was here last year on a one year appointment.  We like to think she stayed due to the great working conditions and great colleagues.  Might it have something to do with working at the scorer’s table at home games or being on a first name basis with Coach Oliver Purnell?


Darren Parker, Ph.D. 1998, University of Wisconsin, Madison, algebra.  Darren has three years experience as an assistant professor at Bemidji State University before coming to UD.  He doesn’t complain of the mosquitoes either and he is spouse to Stephanie Edwards.


Qin (Tim) Sheng, Ph.D. 1989, Cambridge University, numerical partial differential equations.  Tim spent five years at the National University of Singapore and another six years at the University of Louisiana at Lafayette before joining us at the University of Dayton.  We have delivered numerical analysis for ten years now; Tim adds a new dimension, hard computation, to our ability to deliver numerical analysis.




Thomas E. Gantner, Ph.D.

Tom came to the University of Dayton as a first-year student in 1958 and stayed in the old Gibbons Hotel as a freshman.  Upon completing a Ph.D. in mathematics from Purdue, he returned in 1966 as a first year faculty member in the Department of Mathematics.  Tom has produced a full career in teaching and research; his efforts include developing foundational theory in fuzzy mathematics, writing a textbook and developing volumes of new curricula.  Tom recently completed twelve years as the departmental chair where he served with vigor and vision; he has continued a long line of stable and excellent leadership in the department.


John W. McCloskey, Ph.D.


John, known as Jack by friends and colleagues, came to the University of Dayton as a first-year student in 1956.  Jack was one of ten incoming first-year students that year recruited to work for Project Globe, the forerunner of UDRI.  Upon completing a Ph.D. in statistics from Michigan State University, he returned in 1965 as a first year faculty member in the Department of Mathematics.  Jack has a long established record as an excellent teacher and he has developed much of the current statistics curricula.  Moreover, Jack has contributed to the long line of excellence and stability in departmental leadership as he served for twelve years as Chair of the Department of Mathematics.  In retirement, Jack will pursue his many projects in numismatics, where he is a nationally recognized scholar.


Carroll M. Schleppi


Carroll came to the University of Dayton in 1982 as a part-time instructor in mathematics in the School of Engineering; two years later she joined as a full-time faculty member and was a pioneer in the introduction of technology to the calculus curriculum.  In the fall of 1998, Carroll was appointed to a position in the Department of Mathematics where she immediately began to develop as a mathematics education specialist.  She spent the past several years becoming an expert in the NCTM standards and teaching content to future teachers in a hands-on, group learning and student research environment; the experience peaked this past spring when she delivered MTH 205 in the Learning Teaching Center.


Ralph C. Steinlage, Ph.D.


Ralph came to the University of Dayton as a first-year student in 1958; upon completing a Ph.D. in mathematics from the Ohio State University, he returned in 1966 as a first year faculty member in the Department of Mathematics.  Ralph serves as an excellent example for the teacher/scholar model; his efforts include developing foundational theory in fuzzy mathematics, writing several textbooks, developing volumes of new curricula, winning varieties of grant money to fund both technology labs and innovative teaching methods.  He is internationally recognized in the fuzzy mathematics community.  In 1982, Ralph’s university colleagues recognized his excellence as the teacher/scholar and awarded him the Faculty Award in Scholarship.

SABBATICAL:  Aparna Higgins


 I had the privilege of spending my 2000-01 sabbatical at the Department of Mathematics at the United States Military Academy in West Point, NY.  My husband Bill and I shared a one-year appointment, where we both taught in the fall for USMA and spent the spring pursuing professional development and research activities.  I taught plebes (first-year students) the first course of a four-semester sequence of mathematics courses that is required for all cadets (regardless of major!) at the Academy.  The course is highly structured and taught by about twenty instructors in several sections.  Each section has at most eighteen students in it, and each class is student-centered, with students working at boards for some part of each class.  USMA is well suited for trying out pedagogical innovations, and almost all the mathematics courses there incorporate writing, projects, gateway exams, modeling and technology in addition to lectures and tests.  I enjoyed the safety of being able to experiment with these different forms of learning and teaching in a setting where such innovation was expected and not considered so experimental.  I found the dedication of the faculty to be remarkable.  The department consists of about sixty-seven members, about two-thirds of whom are military officers, most of whom are on a three-year rotation.  The department pursues faculty development for all its members vigorously, and successfully persuades its members to conduct research and present at mathematics conferences, in addition to hosting several mathematics conferences on post.  I had the opportunity of advising two senior projects, and appreciated the department’s willingness to let me work with both their beginning students and their graduating students.  I came back from West Point full of respect for a curriculum that imparts good mathematics to all students enrolled there, full of admiration for a group of faculty who teach with enthusiasm, but with a definite sense of relief at being able to plan my own classes for the fall at UD!      




Elizabeth Brooks, Joel Helton, James Goodman and Chris Bomba participated in the 61st Annual William Lowell Putnam Mathematical Competition in December 2000.  Chris Bomba and Michael Grote attended the Annual Pi Mu Epsilon Student Conference in September 2001 at Miami University, Oxford, Ohio with their advisor Dr. Joan Hart Also, Dr. Hovey and some of his students in Probability and Statistics II attended.  Tom Filloon (81), who now works for Procter & Gamble, talked to the Math Club members about what he does as a statistician and career opportunities for math majors in statistics.  Julia Tosi worked as a statistician/programmer with Tom Filloon at Procter & Gamble during the summer.  Chris Bomba represented the UD chapter in the MathFest that was held in August 2002 in Madison, WI.   In the pring of 2002 Math Club hosted the 6th Annual UD High School Math Competition. Due to the incredible financial success of last year's High School Math Contest, Pi Mu Epsilon/Math Club raised enough money to give back to the University Community in the form of a $200 donation to the UDSAP service program for Summer 2001.


Elizabeth Brooks won the Faculty Award of Excellence in Mathematics.  This award goes to the senior who has demonstrates outstanding achievements in mathematics.  Mike Grote won the Pi Mu Epsilon Award for excellence in the Sophomore Class.  This award recognizes excellence in mathematics.




Rachael Kenney obtained a Master of Science (MS) degree in applied mathematics in August 2000.  In 2001 five students, Scott Mitter, Yang Gao, Touhid Khandaker, Chad Bhatti, and Yang Wang obtained MS degrees in applied mathematics.  For their Math Clinic projects, Scott Mitter studied “A One Day Workshop’s Effect on Teacher Attitude Toward Technology” with Janet Herrelko, a faculty member in the School of Education.  Yang Gao studied “The method of quasilinearization and a three-point boundary value problem” with Paul Eloe, Yang Wang studied “Compound Orthogonal Array” with Gerry Shaughnessy, Touhid Khandaker studied “Stability Properties of Linear Volterra Discrete Systems with Nonlinear Perturbation” with Youssef Raffoul, and Chad Bhatti studied “Monotone Methods and Higher Order Boundary Value Problems with Impulse Effects” with Muhammad Islam.  The work of Touhid’s Math Clinic has resulted in a research article, which will appear in the Journal of Difference Equations & Applications. The work of Gao’s Math Clinic has resulted in a research article, which will appear in the Journal of the Korean Mathematical Society. The Math Clinic work of Chad Bhatti, also resulted in a research paper and was presented in a special session at the International Conference on Dynamics of Continuous, Discrete and Impulsive Systems held in London, Ontario, Canada, July 2001.  The paper is currently under review for publication in the proceedings of the conference. Scott Mitter holds a teaching position at Fairmont High School in Kettering, Ohio.  Yang Gao, Yang Wang, Touhid Khandaker, and Chad Bhatti are all pursuing Ph.D. degrees in mathematics or statistics; Gao is at North Carolina State University, Wang is at Penn State University, Khandaker is at Southern Illinois University, and Bhatti is at Rice University.
