Message from the Chair
Due to the pandemic of COVID-19, the past one and a half years have been full of hardships, distance, and uncertainty. Although there have been many difficulties under the pandemic time, the university has placed the priority into our missions: safety and well-being of faculty, staff, and students. To achieve this goal, the teaching format was redesigned as three types in AY 2020-2021: asynchronous online, synchronous remote, and hybrid teaching. The hybrid teaching involves in-person components. To effectively teach math courses, our department worked together to manage hybrid teaching in 1000 and 2000-level math classes. The assistant chair, course coordinators, staff, and the chair had made a great commitment to communicating with upper-level administrators, faculty, and students to put the students in classrooms for meeting the requirements of the social distance restriction. In the hybrid teaching of math classes, we had ensured each instructor met students in the classroom at least one time weekly.
Under the supervision of university guidelines in AY 2020-2021, alternative work arrangements (AWA) were adopted, faculty and students therefore had opportunities to make a choice on learning formats and on grading options. Although such procedures provided great flexibility to the individuals who had certain needs, practically a wide spectrum of choices from the faculty and students had posed numerous challenges for the department. Further, the math department has lost quite a few faculty members due to retirements and resignations. To overcome these problems, the math faculty and graduate students had passionately undertaken and gone through a variety of trainings including spontaneous mutual assistances on how to use electronic tools for remote teaching and participation in the trainings held by the university on how to construct a good Canvas online course. With our collective engagement, the department had experienced a smooth transition during the tough time, and the math courses had been effectually covered across campus.
There have been many highlights in our math department.
A new math course, Math 1190, was created and offered from Fall 2019. Math 1190, Real World Math Skills, a four-credit course, is offered for students to develop and use the concepts of numeracy to investigate and explain quantitative relationships and solve problems in a variety of real-world contexts. This newly developed course provides extensibility and more options for students to learn quantitative reasoning in both mathematical and practical views.
Congratulations to Ms. Irina Franke for promotion to teaching professor and to Ms. Konra Holman for promotion to associate teaching professor.
In Spring 2021, it was excellent to welcome one new faculty member, Ms. Lada Carlisle. She works as an assistant teaching professor and teaches college algebra in the Math Emporium.
We also congratulated Dr. Craig Zirbel on his receipt of a $1,497,713 grant from U.S. Department of Health and Human Services of NIH in support of his project "Integrated Resource for Nucleic Acid Structures.” As the PI, Dr. Zirbel was informed this good news in December 2020, and has started working on this project with his research team.
Our congratulations also went to Drs. Wei Ning and Ben Ward for respective receipt of a Collaboration Grant for Mathematicians from the Simons Foundation in Fall 2020. Their Collaboration Grants began on September 1, 2020. A small part of each awarded grant will be utilized to support the departmental colloquia and seminars, support for student orientations, and other graduate student activities, which will benefit the development of the department.
In Fall 2021, we were very excited to welcome two new hires, Dr. Riddhi Ghosh and Ms. Courtney Wilcox. Dr. Ghosh works as an assistant professor in statistics/data science. Ms. Wilcox works as an assistant teaching professor in the Math Emporium.
On September 24 of Fall 2021, two external reviewers for math/stat program reviews, Dr. Karen Kadafar from the University of Virginia and Dr. Michael Davis from Ohio State University, visited the math department. They met the math faculty in different research groups including stat/prob/data science, pure applied math, and math education. The external reviewers also observed a class and talked with the faculty in the Math Emporium. Undergraduate and graduate student representatives from each of the math and statistics programs met the reviewers and remarked on the programs. The foundational math, undergraduate committee, and graduate committee groups respectively met with the external reviewers as well. Through these beneficial and informative meetings, Dr. Kafadar and Dr. Davis clarified their questions about the programs. The department is truly appreciative of their time and support to the math/stat program reviews.
We are very proud of the strategies, bravery, and dedication we put on under the pandemic in almost the last two years. At present, BGSU comes back to in-person teaching. However, the pandemic persists with more COVID virus variants, we are still facing many risks and challenges imposed by the pandemic. We now expect to handle all problems proactively and optimally in future years, though we know that the front road could be very tough. We all wish that the pandemic recedes, and the world returns to normal soon.

Remembrance
Josef Blass (1945-2020)
Josef Blass passed away at his home in Chapel Hill, North Carolina on October 2, 2020. He was born in 1945 in Krasnoturyinsk, Novosibirsk, USSR. Josef immigrated to the United States in 1968 and earned his PhD in mathematics in 1970 at the University of Michigan. He taught at BGSU 1970-2000.
During his time at BGSU, Josef taught Mathematics and ran the Actuarial Program, with enrollment in the actuarial program ballooning in size with Josef, always a salesman at heart, promising and delivering well-paying jobs in the insurance industry to countless undergraduates. Josef and his wife, Eva, had two children, Katherine Marie Blass and Andrew William Blass, who were born in Ann Arbor to a newly minted Doctor of Mathematics and a Medical Student. The new math professor found a teaching position in Bowling Green, Ohio. For two years, Josef commuted from Ann Arbor to Bowling Green to teach at BGSU, which resulted in a lifelong disdain for car trips and long commutes.
Josef spent the better part of his time studying and playing bridge. As a bridge sponsor, he played at the highest level of world competitive bridge. With his team, he won a number of events in international, national, and regional tournaments. Josef was beloved in the bridge world for his rigorous approach and warm personality. In 2018, after a hiking trip with Eva and friends, he developed problems with his liver which began the steady decline of his health. Despite that, he played bridge tirelessly and spent his time off with his family - his two greatest loves.
Josef's obituary can be read on the Sentinel Tribune website.

Anna Kelling (1992-2021)
We were very saddened that we lost Ms. Anna Kelling on March 23, 2021. She served as the Graduate Secretary for the department for almost five years and worked in Student Financial Aid prior to joining the department. She was an active member of the Classified Staff Council and volunteered in the Bowling Green community, Serenity Farms in Pemberville, Ohio, and anywhere else she could interact with people to make a difference.
Anna brought a lot of joy to this department with her caring and open nature. She was a true friend to the graduate students, faculty, and many more throughout the university. She will be remembered for being thoughtful, compassionate, bright and bubbly, and one who was highly involved with such creativity. Anna was finishing a degree in Social Work in the summer of 2021 and was scheduled to begin her Master of Social Work program in fall 2021 at BGSU.
Her passing was a great loss to the department, and she is greatly missed by all of us. In memory of Anna, a memorial scholarship at Bowling Green State University was established for students studying social work and associated professions. Math faculty and graduate students have contributed to the fund. Contributions can be made to the Anna Kelling Scholarship Fund through the BGSU Foundation, 1851 North Research Drive, Bowling Green, OH 43403.
W. Charles Holland (1935-2020)
W. Charles Holland (1935-2020), Mathematics and Statistics Department Chair 1981-1983, passed away on July 30, 2020, in Atria senior community, Longmont, Colorado. He was 85. Charles earned a Ph.D. in mathematics from Tulane University in New Orleans, Louisiana, in 1961. He taught at BGSU from 1972 to 2002. In 1993, University Board of trustees named Mr. Holland a Distinguished Research Professor. The honor is one of the highest awarded by the University to a faculty member. He was recognized as a world leader in an area of algebra known as ordered groups.
Charles performed with the Black Swamp Players, including Gilbert and Sullivan's The Pirates of Penzance and Ruddigore. He took part in racquet sports and played the piano. Earlier, he'd played trombone and built a harpsichord and a clavichord.
He and his wife, Claudia, moved from Bowling Green to Colorado - Boulder, then Longmont - after his retirement from BGSU. He returned to BGSU in 2009 for the annual International Conference, during which he was honored.
"He came up with some clever ideas," said Tom O'Brien, a BGSU math professor emeritus. "He was a multi-talented guy. He was a fine mathematician. He was a musician. He was an excellent teacher. He was good at everything he did."
Dr. Richard Ball, a professor emeritus of mathematics at the University of Denver, said: "He was an inspiration. He was the reason I became a mathematician."
Former BGSU mathematics faculty member, Gabor J. Szekely, said, "Charles was my office neighbor for ten years. His area of research, lattice ordered groups, was very far from mine, but we could chat on lots of other things, like how to make good American breakfast, how to read American politics and where to find good beer. He taught me how to play squash and how to TeX my writings. Eventually he explained to me what lattice ordered groups are. He was an excellent teacher because a few weeks later we could write a joint paper on lattice ordered groups for Algebra Universalis and then another paper on integer valued means (jointly with Curt Bennett).
"We were guests of Charles and Claudia, his wife, many times. We met them frequently at the BGSU Ice Arena and at the Toledo Opera. Charles was also a good singer with a nice voice, and we enjoyed his performances with Department barbershop quartet, The Logarhythms. When Charles retired in 2005, at the age of 70, I felt that the soul of the Department left us."

Grants Awarded to Math Faculty
Professor Wei Ning received a grant to fund his project titled "Empirical-Likelihood-Based Sequential Changepoint Detection Methods for High Dimensional Data" sponsored by the Simons Foundation. The grant will provide $42,000 over the next five years for a long of list of research expenses including scientific travel for the researchers and their students, inviting speakers and visitors from other universities to visit BGSU, funding department seminars and colloquia, and paying for research materials. This five-year grant is designed to increase collaborative contacts between mathematicians and statisticians.
Professor Alexander Izzo has been awarded a three-year grant from the National Science Foundation for a research project concerning new developments at the interface of Banach algebras and complex analysis. In addition to providing support for Dr. Izzo (Principal Investigator) and travel funds, the grant also provides support for a graduate student research assistant. Dr. Izzo also received an award from the Simons Foundation for his project titled “Uniform Algebras and Analytic Structure.”
Assistant Professor Ben Ward was awarded a Collaboration Grant for Mathematicians from the Simons Foundation. This funded project is titled “Rational Homotopy Type of Graph Complexes.” This is a five-year grant designed to increase collaborative contacts between mathematicians and statisticians. The grant will provide funding for Dr. Ward to work with his collaborators and to invite other mathematicians and statisticians to BGSU. A portion of the $42,000 grant will be used to support departmental colloquia and seminars, as well as refreshments and other research-related amenities; to fund student orientations, prospective student visits and other departmental activities; to subsidize meals for faculty, students, and visitors; and to facilitate research activities on furniture and research infrastructure, such as copiers, computer servers and computer support.
Associate Professor Kimberly Rogers has developed and implemented an NSF-funded peer-mentoring program for graduate student instructors. As PI on multiple NSF projects she helps experienced graduate students become effective peer-mentors and facilitate and coordinate a peer-mentoring program focused on developing graduate students’ abilities to implement active-learning techniques in mathematics departments across a number of universities. She received an award from the NSF Education & Human Resources for Collaborative Research: Mathematics Graduate Student Peer Mentoring in 2019.
Professor Craig Zirbel and his long-time collaborator Neocles Leontis in Chemistry at BGSU were awarded a renewal of funding from the National Institutes of Health. This $1.5 million grant will fund work in RNA bioinformatics from September 2020 to August 2024, which brings them to a total of 12 years of NIH funding. The project is the continuation of a collaboration between the BGSU RNA Group and researchers at Rutgers University who run the Nucleic Acid Database. Over the years, the collaboration has developed and made available to the research community various annotations of RNA 3D structures and tools to search them and to infer 3D structure from sequence alone. The NIH funding has supported nine Ph.D. students and two Master’s students and provided projects and learning experiences for undergraduates and high school students.
DNA is a molecule made up of a long chain of A, C, G, T nucleotides, which encode our genetic information in essentially a digital format. DNA is analogous to the hard drive on a computer; suitable for long-term storage of programs and data. By contrast, RNA molecules are like the programs that get read off the hard drive at the right time, making things happen, and then get cleared out. RNA molecules are relatively short chains of A, C, G, U nucleotides and only persist in the cell for a few hours to a few days, but during that time they interact with proteins and other molecules to help regulate our metabolism, detect changes in temperature and the levels of important metabolites, and determine where and when certain parts of the DNA are read. Both DNA and RNA carry out many of their roles by virtue of the 3D shapes that they form, which research groups around the world determine to atomic precision and deposit at the Protein Data Bank. The analysis pipeline developed at BGSU will download these 3D structures, annotate and organize them, identify recurrent motifs within them, allow researchers to search them for other motifs of interest, and provide tools to predict 3D geometries from nucleotide sequence. Analyzing DNA 3D structures and the interactions between RNA/DNA and proteins will be new in this four-year period. The work done by the group is posted online with weekly updates.
Tragically, Professor Leontis died in a car crash in December 2020, shortly after the final grant notification was received. This was a great loss to the BGSU community, the City of Bowling Green, and the RNA research community. Dr. Leontis was constantly in motion, trying to make the world a better place. Among his many contributions to BGSU, he served as Chair of Faculty Senate, served on the committee that wrote the BGSU Climate Action Plan, and led an Innovative Teaching Group of faculty. He was elected to the Bowling Green City Council in November 2019 and worked to improve rental regulations and move Bowling Green toward carbon neutrality. He was a founding member of the Black Swamp Green Team and worked with local churches and utilities to get houses insulated to save money and reduce carbon emissions.
He and Dr. Zirbel started working together on RNA bioinformatics in 1999 when they jointly supervised an undergraduate chemistry and mathematics double major who went on to earn a Goldwater Scholarship. In 2020, another joint student earned a Goldwater Scholarship. Together they wrote 27 research papers and worked together to supervise 12 Ph.D. students in Biology and in Statistics. You can read a remembrance written by Dr. Zirbel and his obituary.
Award to a Doctoral Student
Doctoral recipient Suthakaran Ratnasingam was awarded the 2020 Graduate College Distinguished Dissertation Award. The committee found his dissertation, "Sequential Change-Point Detection in Linear Regression and Linear Quantile Regression Models Under High Dimensionality," to be an "outstanding and sophisticated example of scholarly research." He was under the supervision of Dr. Wei Ning.
