### Department News & Announcements

**Dr. Carl Mautner Joins UC Riverside Mathematics**Dr. Carl Mautner has joined the department as an Assistant Professor working in pure mathematics. He earned his Ph.D. from the University of Texas at Austin and comes to Riverside after postdoctoral work at Harvard University and the Max Planck Institute for Mathematics.

Dr. Mautner's research lies at the intersection of a number of areas of mathematics, including algebra, geometry, topology and combinatorics. He is currently exploring connections between representation theory, a study of symmetries, and the topology of algebraic varieties, spaces of solutions to algebraic equations. These connections shed light on long-standing questions in representation theory and create new directions of inquiry.**Dr. Amir Moradifam Joins UC Riverside Mathematics**Dr. Amir Moradifam is an assistant professor of mathematics working on Partial Differential Equations, Inverse Problems in Medical Imaging, and Mathematical Biology. He earned his Ph.D. from the University of British Columbia, and did postdoctoral work at Columbia University and the University of Toronto. Dr. Moradifam’s recent research focuses on hybrid inverse problems that aim at combining exterior measurements with interior ones to obtain images with higher resolution and contrast than previously available by classical methods. He is also working on mathematical modeling of cell division in plants.

**Dr. Yulong Xing Joins UC Riverside Mathematics**Dr. Xing is an assistant professor working in computational mathematics. Prior to joining UCR, he was a staff scientist at Oak Ridge National Laboratory, and held a joint appointment at the University of Tennessee. He works on the design, analysis and implementation of accurate and efficient numerical methods for differential equations arising from science and engineering problems. His current research focus is on the development of high order numerical methods, including finite element discontinuous Galerkin, finite volume and finite difference methods, for various applications in hydraulic engineering, astrophysics, atmosphere and climate science.

**Dr. Vyjayanthi Chari of UCR invited as a Plenary Speaker to the TORA Conference**Texas-Oklahoma Representations and Automorphic forms (TORA) is a series of conferences hosted in rotation by Oklahoma State University, the University of Oklahoma, and the University of North Texas. The TORA meetings bring together the automorphic forms and representation theory community of the South Central region to hear about recent research in automorphic forms and representation theory.

TORA Dates: Friday, April 8 - Sunday, April 10, 2016.

**John Baez to Speak at Winter Meeting of Canadian Mathematical Society**On December 5, 2015, Prof John Baez will give a public lecture at the winter meeting of the Canadian Mathematical Society in Montreal.

The title of his talk is "The answer to the ultimate question of life, the universe, and everything". It is about some curious mathematical properties of the number 42. According to Prof Baez, this is based on a joke by the writer Douglas Adams, in which the number 42 was the answer to the ultimate question. The CMS winter meeting is the primary annual mathematics meeting in Canada. The CMS annual meetings have been running since 1945, so this year marks their 70th anniversary. According to an organizer, the meeting typically has 300-400 participants, but this year will likely set a record -- closer to 500. The public lectures are meant to bring interesting mathematics to a broad audience. They are given by scientists of international renown who are also known for their efforts in mathematics outreach or popularization, or for bridging the gap between mathematics and other disciplines.

**UCR Professor and Grad Give Talks at 9**Seven women from the UCR Mathematics Department participated in the 9th Annual Symposium for Women in Mathematics in Southern California (WiMSoCal) at Pomona College on November 7. The symposium included contributed talks in all areas of mathematics, a plenary lecture, and networking opportunities. Graduate student Lauren Ruth (see photo) and Associate Professor Julie Bergner both gave contributed talks. The other participants were graduate students Andrea Arauza, Donna Blanton, Kayla Murray, and Christina Osborne, and undergraduate students Sarah Belknap and Diana Hamideh.^{th}Annual Women in Math Symposium

**John Baez to Speak at Broadcom**On November 18, 2015, UC Riverside Math Professor John Baez will give a talk on category theory and electrical circuits at Broadcom. Broadcom is a FORTUNE Global 500 company. It is a semiconductor company with more than 11,250 U.S. and 4,100 foreign patents. Prof John Baez has been invited by Broadcom's central engineering group.**Mathematician Named Fellow of American Mathematical Society**Mathematician Vyjayanthi Chari at the University of California, Riverside is one of only 50 mathematical scientists from around the world who have been named fellows of the American Mathematical Society (AMS) for 2016. Chari, a professor of mathematics, is honored for “contributions to the theory of quantum groups and affine Lie algebras, and for service to the mathematical community.”

“Dr. Chari has been well regarded by her colleagues for her contribution to mentoring graduate students and postdocs,” said Yat Sun Poon, the chair of the Department of Mathematics at UC Riverside. “She is well known among Lie theorists, and very well cited. She is leading UC Riverside’s Lie theory research group, and beyond. We are proud of her achievement, and feel fortunate that she is on our faculty.”**The 2014–15 Graduate Dissertation**Each year the Graduate Council and Graduate Division present the Doctoral Dissertation Advisor/Mentor Award to one or two UCR faculty members who have made outstanding contributions to the training of advanced graduate students. It is my pleasure to announce that this year’s winner is Vyjayanthi Chari. Dr. Vyjayanthi Chari is a Professor in the Department of Mathematics. She received her BS (1976) and PhD (1988) in Mathematics from Bombay University. She has been at UCR since 1991, where she started as an Associate Professor and is presently investigating new directions in Lie Theory. Over the years, Dr. Chari has mentored an impressive number of graduate students—27 in total; however, her students uniformly report that Dr. Chari provided timely guidance for professional, educational, and personal matters. Many students cited Dr. Chari as one of the most influential people in their lives. Furthermore, it is clear both from the eloquent nature of the supporting letters and the prestigious positions held by those who wrote them that Dr. Chari produces articulate, successful mentees. For her many efforts in mentoring graduate students, she is being honored with the Doctoral Dissertation Advisor/Mentor Award.

Mentoring Award: Professor Vyjayanthi Chari**UCR Grad Awarded Fulbright Fellowship**UC Riverside's Mathematics Department is proud to announce graduate student Matthew O'Dell has been awarded a graduate level Fulbright U.S. Student Program Fellowship. His Ph.D. supervisor, Dr. Vyjayanthi Chari, and Matthew's thesis is on topics in the Representation Theory of The Current Algebra. Matthew will pursue certain aspects of the subject during the 2015-2016 academic year at the University of Cologne, North Rhine-Westphalia, Germany.**American Mathematics Competition at UCR**UC Riverside's Mathematics Department participates and supports the Mathematical Association of America (MAA) with their annual American Mathematics Competitions (AMC Contests). We work with local middle schools and high schools to prepare students to take the AMC tests. We recognize and honor the top scorers each year who rise to the challenge. The graduate students from UCR’s Mathematics Program visit the schools and offer weekly tutoring to help prepare the students leading up to the test day. These competitions highlight the mental talents of many young minds and help promote a deeper interest in one of the most important academic fields. Check out the current AMC results for more information.**UCR Math Club**The purpose of the UCR undergraduate Math Club is to encourage and enhance students' understanding of upper division mathematics. Anyone who comes to the meetings will meet other students with mathematically inclined interests. The group hosts events throughout the academic year. The Math Club also participates in the William Lowell Putnam Mathematical Competition which offers prestige and scholarship prizes. More information on the UCR Mathematics Department's participation can be found on this page.
