In these videos the viewers are guided to develop the contents of physical or biological problems into mathematical formulation, and then solve the problem mathematically afterward. This project is funded by UCR Provost’s Office.

Dr. Qi Zhang, Graduate Advisor for recruitment, organized the event.

For the morning events, six graduate students spoke on their research. In particular, Donna Blanton spoke on representation of Lie algebras; Kaylee Hamann spoke on Greene-Krantz conjecture in complex geometry; John Simanyi highlighted the use of topological invariants in classification of spaces in dimension four and below. Andrea Arauza discussed how ideas from non-communtative geometry are used to study fractal geometry. Jordan Tousignant described how category theory provides a general setting for module theory. Robert Willet introduced, to the audience, the concept of Gromov Hausdorff convergence.

In the afternoon, after Dean Cindy Larive’s welcoming remark, four professors highlighted some of their current research.

Speaker: Kevin Costello Title: The power of randomness Abstract: Sometimes, when you want an object or an algorithm to have certain properties, "close your eyes and pick" turns out to work a lot better than even the most careful of constructions.

Speaker: Daniele Rosso Title: Representation Theory Abstract: Representation Theory is the study of symmetries, combining abstract algebra and linear algebra

Speaker: Amir Moradifam Title: Hybrid Inverse Problems in Medical Imaging Abstract: A brief introduction to Hybrid Inverse problems and Current Density Impedance Imaging will be presented

Speaker: John Baez Title: Network Theory Abstract: The world is full of networks, from electrical circuits to social networks. Only mathematicians can think abstractly enough to study all these networks in a unified way.

**UCR's Dr. Michel Lapidus leads the 2016 Joint Mathematics Meetings in Seattle**Prof. Michel Lapidus was the AMS Associate Secretary in charge of the scientific program and organization of the 2016 Joint Mathematics Meetings (JMM) in Seattle, WA, January 6-9, 2016.

The JMM combines the annual meetings of the American Mathematical Society (AMS) and the Mathematical Association of America (MAA), as well as as hosts sessions of several other mathematics organizations such as ASL (http://www.aslonline.org/index.htm), AWL (www.awm-math.org), NAM (http://www.nam-math.org/), and SIAM (http://www.siam.org/). The JMM is the largest mathematics meeting in the world. This year's meeting has gathered nearly 6,300 participants. It featured many invited addresses, 80 AMS special sessions, and thousands of contributed talks. For further information, click here (http://jointmathematicsmeetings.org/meetings/national/jmm2016/2181_intro).

This is the fourth JMM for which Dr. Lapidus has been the AMS Associate Secretary. The previous ones have been the 2004 JMM in Phoenix, the 2008 JMM in San Diego, as well as the 2012 JMM in Boston, which was the largest mathematics meeting ever of any kind, gathering over 7,300 participants.**Instructional Coach for Val Verde Unified School District Gives Talk at UCR**On March 7, Mr. Michael Towne gave a seminar talk on "Responding to Student Misconceptions to develop Conceptual Understanding”. Michael Towne has taught elementary, middle and high school mathematics and science. He currently serves as the Instructional Coach for Val Verde Unified School District and is a Ph.D. student in the GSOE at UCR and serves as a instructor in the teacher preparation program. Mr. Towne trains teachers, speaks at teacher professional development programs and conferences around the country and is an advocate for improving instructional practice at all levels.On February 9th, UCR hosted the RUSD Science Fair. Visiting Assistant Professor Michael Hartglass and Assistant Professor of Teaching David Weisbart, together with PhD students Alexander Henderson and Thomas Schellhous, represented the Mathematics Department in the judging of the Mathematics & Software category. Tenth grader Preetha Krishnamurthy of King High School was awarded a first place award for her superb work involving the assessment of similarities in object textures and tenth graders Joanna Fernandez-Fuentes and Alejandra Calzada of Poly High School shared a second place award for their insightful collaborative project on precise questioning and answering. All three young researchers show great promise and the judges look forward to hearing about the many accomplishments these students will have in the future.

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.

**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.
