This #FacultyFriday features Joanna Jauchen, Instructor, Associate Chair for Teaching, Mathematical Sciences, is this week's #FacultyFriday feature. Jauchen specializes in intersectional, critical feminist STEM education research on faculty engagement in diversity, equity, and inclusion (DEI) service. While she has always enjoyed math, she fell in love with the beauty of the discipline in their undergraduate studies, “It sometimes feels magical the way things work together in mathematics and I like understanding how the magic works,” she said. As an educator, she finds joy in talking to students about their own understanding of mathematics.

This #FacultyFriday features Mahamadi Warma, Professor, Mathematical Sciences. Warma is currently working on two major research projects with approaches based on the rich and fruitful mathematical apparatus offered by PDE, functional analysis, controllability, optimization, and numerical approximations. He has published a total of 79 papers, with seven of those published in 2022. Warma is very active in the Center for Mathematics and Artificial Intelligence (CMAI) at Mason. His passion for math started in high school and continues to grow as he faces new challenges with an eagerness to solve them.

Our first #FacultyFriday feature of the month kicks off with Rebecca R.G., Assistant Professor, Mathematical Sciences. R.G.’s research is in commutative algebra, a field of math that involves studying the behavior of algebraic objects like rings and modules. R.G. is passionate about supporting students and creating a space for everyone to do math. As a result, she worked with colleagues to organize several multiple programs including the New PhD Mentoring Program, the Graduate Learning Assistants (GLA) Program, and the PhD Launchpad Program. R.G. is a big advocate for active learning, reflected in her newly designed course, History of Math (joint with Jessica Otis). Be sure to stop by her office to see crocheted models of hyperbolic planes and a Sierpinski triangle shawl.

Dan Anderson, along with two co-authors, Peter Guba and Andrew Wells, has been published in the February 1, 2022 issue of Physics Today. Physics Today, the flagship publication of the American Institute of Physics, is the most influential and closely followed physics magazine in the world. The article, "Mushy-layer convection," aims to provide a physical understanding of mushy layers by describing the mechanisms behind their convective processes. The synergy between analytic models, laboratory experiments, and computational simulations has been instrumental in developing a comprehensive picture. The article begins by explaining how mushy layers form, features two ubiquitous examples—one from Earth’s cryosphere and another from metallurgy—and concludes by highlighting new insights into convective phenomena in ternary systems.  https://physicstoday.scitation.org/doi/10.1063/PT.3.4940

After two years of development, on November 18, 2021, in Richmond, the Virginia Board of Education was presented with the first-ever High School Data Science K-12 Standards of Learning and Data Science Curriculum Framework. Five lead taskforce members, including our own Professor Padmanabhan (Padhu) Seshaiyer as well as others from Fairfax County, Prince William County, and Frederick County Public Schools, and the Virginia Department of Education, were in attendance as key to the process.   

The Board was very pleased with the work and commended GMU and Professor Seshaiyer specifically for their part in the development. They accepted the plan under "first review" and will proceed now to the next steps of public review. As this evolves in the coming months, all high school students in the entire state of VA will have the option to take this new class and will enter college proficient in data science – no matter the particular field of study they choose to pursue.    

The recording of the entire BoE meeting is available at this YouTube link. The specific data science session confirmation is about 25 min long (from 00:59:08 to 01:23:45) YouTube link 

Mason professor Evelyn Sander has been elected to the leadership Council of the Society for Industrial and Applied Mathematics (SIAM). SIAM is an international community of over 14,000 individual and over 500 institutional members. They are a non-profit organization committed to advancing research in, and application of mathematics and computational science. In her candidate statement she committed to helping SIAM make strides in D&I, saying, "Within mathematics, SIAM stands out for its attention to diversity and inclusion of members of groups who are traditionally underrepresented in mathematics, including diversity of race, ethnicity, gender, and geography. However, severe inequity remains, and the Council should focus on changes that encourage inclusion."

Congratulations, Professor Sander!

Harbir Antil, Professor, Mathematical Sciences; Director, Center for Mathematics and Artificial Intelligence, is studying optimization problems with partial differential equation (PDE) constraints.  

He and his collaborators aim to create new optimization methods Deep Learning frameworks to solve several currently intractable optimization problems constrained by: fractional harmonic maps, advection dominated (also limiting transport equations) arising in magnetic targeted drug delivery, general inequality and equality constraints such as contact or complementarity. All these problems are nonlinear, nonconvex, and nonsmooth in nature. 

Antil received $340,000 from the National Science Foundation for this project. Funding began in August 2021 and will end in late July 2024. 

Maria Emelianenko, Chair and Professor, Mathematical Sciences, is set to receive $42,000 from the Simons Foundation to study mathematical methods for materials and biological network analysis. 

"This work is focused on developing mathematical tools able to quantify and predict structural characteristics of materials and biological networks in connection with specific properties of interest. In particular, these theoretical investigations will allow [for the elucidation of] the mechanisms responsible for changes in network statistics due to cancer mutations (in biological pathways) or heat treatment (in materials). Ultimately, these insights will pave a way toward a better understanding of adaptation and damage resistance in these diverse yet intrinsically linked natural systems," Emelianenko said. 

This funding will begin in September 2021 and will end in late August 2026. 

Padmanabhan (Padhu) Seshaiyer, at Mason since 2007, is a professor in the Department of Mathematical Sciences and associate dean for academic affairs in the College of Science. In his research he develops analytical techniques and computational algorithms in an effort to understand and solve a wide range of problems, including the physiology of the human vascular system, the mechanics of brain aneurysms, the motion of micro-air vehicles, the spread of the Zika virus, and drone-based efforts to prevent elephant and rhino poaching in Tanzania. Seshaiyer has initiated and directed a variety of educational outreach programs and received many high-profile awards for his teaching, research and outreach.

Meet #MasonScience Mathematical Sciences Professor Maria Emelianenko. Emelianenko is an interdisciplinary mathematician who applies mathematical theory to a wide range of problems across the sciences. She directs Mason's Industrial Immersion Program and advises the Women in Mathematics student organization George Mason University.

Members of the math department at George Mason University Drs. Anderson, Emelianenko, Seshaiyer, Warma and I (Sander) attended the Math Alliance’s graduate student fair. The Math Alliance is a group committed to promoting diversity in doctoral studies in the mathematical sciences; GMU math has recently become an institutional member. While some members of our group had previous experiences with the group, I never had. It was a great experience, to meet prospective graduate students from underrepresented minorities from all over the country. The meeting was on Sococo, a platform which looks a bit like a moving map of a conference with little dots for each of the participants. I had a chance to chat in the lobby with a number of faculty, graduate students, and undergraduate students who were attending the event. It gave students an opportunity to ask questions on graduate admissions and career preparation, and it gave faculty a chance to profile their programs and get their names onto the map. It was quite inspiring to see how many of the highest rated universities in the country were represented at this event. It gives me hope that as a community, we will be able to address the striking underrepresentation in the profession. I look forward to working in a greater capacity with the Math Alliance, by attending the career fair next month, and in future by serving as a mentor, and working with  underrepresented students in helping to prepare them for graduate school and careers in mathematics. 

Mason professor Rebecca Goldin has been elected a Fellow of the American Mathematical Society for "contributions to differential geometry and service to the mathematical community, particularly in support of promoting mathematical and statistical thinking to a wide audience." Rebecca is the first GMU math professor to be so honored. Congratulation, Rebecca!

Swan Klein gave an invited presentation on “Two-Qubit Quantum Circuit Synthesis” at the WoPhyS 2021 Conference on Thursday, October 21. 

WoPhyS 2021 is the 12th Annual Conference of the serial conference held by the University of Nebraska– Lincoln (UNL) affiliated materials science centers. It brings together outstanding women researchers in the physical sciences, along with their supervising faculty, for a three-day conference covering research topics in STEM areas. 

One of the objectives of the WoPhyS conference is to provide undergraduate and graduate students with a platform to present their research to their peers. This rare opportunity to be an invited speaker at a conference as a student researcher will allow students to develop their ability to present scientific ideas and information.  Congratulations Swan.

Abstract:

Every single-qubit Clifford+T operator can be uniquely written in a T-count minimal normal form circuit. Furthermore, a linear-time algorithm exists for computing the normal form of every Clifford+T operator. Our goal is to find a normal form for the two-qubit Clifford+T gate set using the SO(6) representation of the Clifford+T operators. It is desirable to represent circuits using as few T gates as possible as it is more computationally expensive to use T gates than Clifford gates. We intend to use the results of an algorithm we wrote to exhaustively compute the patterns of Clifford+T circuits with up to 10 T gates to give us insight into developing a normal form and exact synthesis algorithm, which would aid in the efficient implementation of quantum algorithms.
