Congratulations to Chole Makdad - Golwater Scholarship Recipent

The Mathematics, Statistics, and Actuarial Department would like to congratulate Choloe Makdad, a sophomore mathematics, statistics, and computer science major for being named our most recent Goldwater Scholarship recipient.  

The Goldwater Scholarship is the most prestigious undergraduate scholarship in the natural sciences, mathematics, and engineering in America. According to the Goldwater Foundation, 396 college students from across the U.S. were selected to receive the scholarship from an estimated pool of more than 5,000 college sophomores and juniors. A total of 1,343 natural science, engineering, and mathematics students were nominated by 461 academic institutions to compete for the 2020 Goldwater scholarships. Of students who reported, 191 of the Scholars are men, 203 are women, and virtually all intend to obtain a Ph.D. as their highest degree objective. Fifty Scholars are mathematics and computer science majors, 287 are majoring in the natural sciences, and 59 are majoring in engineering. Many of the Scholars have published their research in leading journals and have presented their work at professional society conferences.


“Honorable Mention” of Bulldogs at JMM2020!

Seven of our majors, Jayme Brickley, Jacob Charboneau, Chloe Makdad, Dave Purdum, Benjamin Rempfer, Gwen Spencer and Dejuan Winters, presented posters from their research at the Joint Mathematics Meeting (JMM) in January (January 15th to 18th), in Denver CO. JMM is organized annually by the Mathematical Association of America (MAA) and the American Mathematical Society (AMS), and it is the largest mathematics meeting in the world.

There were 361 poster presentations by undergraduates from all around the Unites States. The poster presentations by Chloe, Ben, Gwen and Dejuan were among “Honorable Mention” posters at the poster session.

  • Jayme Brickley (Mathematics and Chemistry, advisor Dr. Stefano Silvestri)   "Dynamics on Checkerboard Julia Set”
  • Jacob Charboneau ((Mathematics and Computer Science, advisor Dr. Ankur Gupta) “Finding Small Modulo Difference Covers”
  • Dave Purdum (Mathematics, Statistics, Computer Science, advisor Dr. Amber Russell) “Automorphisms of Integral Polynomials and Their Stabilizers”
  • Benjamin Rempfer (Mathematics and Physics, advisor Dr. Scott Kaschner) “Geometric Limits of Julia Sets for a Non-Hyperbolic Siegel Disk Map”
  • Gwen Spencer (Actuarial Science, advisor Dr. Rasitha Jayasekare) “Model-Based Cluster Analysis of Indiana Social Security Beneficiary Data”
  • Dejuan Winters (Mathematics and Physics, advisor Dr. Scott Kaschner) “Geometric Limits of Julia Sets with a Parabolic Implosion” 
  • Chloe Makdad (Mathematics, Statistics, and Computer Science) “Solving Linear Systems on a Distributed Network with the Kaczmarz Method” with results from her Research Experience in Undergraduates (REU) at Iowa State University last summer. There were 361 poster presentations by undergraduates from all around the Unites States. The poster presentations by Chloe, Ben, Gwen and Dejuan were among “Honorable Mention” posters at the poster session.

Algorithmic Number Theory Research Runs in the Family at Butler

Check out the Butler University News to read about father and daughter research at Butler.  Brianna is a mathematics and computer science major and has been working with her father on mathematics and computer science.  The full article can be found at Butler Stories Newsrom.  As an added fun fact, David Purdum, a senior mathematics and statistics, and computer science maor, is also mentioned in the article for his research.


Pi Mu Epsilon Conference

Friday, September 20, 2019

Dr. Scott Kaschner, David Brickley, Jacob Charboneau, Ben Rempfer. Chloe Makdad, Troy Wiegand, DeJuan Winters, Dr. John Herr

Congratulations to six of our majors presenting at the 46th Annual Pi M Epsilon Student Conference, part of the 47th Miami of Ohio University Anual Mathematics Conference:  Differential Equations and Dynamical Systems and Their Applications.  Students began their research during Mathematics Research Camp in August 2019, with work continuing into the school year.  

Dr. Scott Kaschner gave a talk on Superstable Manifolds and the Ising Model on Hierarchical Lattices.   

Student talks included the following:
David Gregory and Jacob Charboneau: Finding Small Sizes of Modulo Difference Covers
Ben Rempfer: Geometric Limits of Julia Sets for a NonHyperbolic Siegel Disk Map
Chloe Makdad: An Extension Theorem for Bicomplex Functions
Troy Wiegand: Discerning Complex Hadamard Submatrices of the Fourier Matrices via Primitive Sets
DeJuan Winters: Geometric Limits of Julia Sets with a Paraolic Implosion

Science Building Renovation

To keep pace with a rapidly changing world and continue preparing our graduates for the science of the future, it’s time for a bold investment to repurpose and renovate science facilities that match the high caliber of our students and faculty.
