You can learn more about Fred at his website. Faculty News New Faculty Please join me in welcoming a new face to the department’s faculty: Noah Giansiracusa began as a new assistant professor this fall. Dr. Giansiracusa received his Ph.D. in 2011 at Brown University. After that he spent a year as a postdoctoral fellow at the University of Zurich and two years as an NSF postdoctoral fellow at the University of California, Berkeley. Dr. Giansiracusa joins our research group in algebraic geometry, with particular interests in invariant theory, tropical geometry, and moduli of curves. Faculty Awards Dr. Michael Usher: Creative Research Medal Creative Research Medals are awarded to outstanding UGA faculty for an exceptional research project or creative activity with a single theme completed within the last five years. Dr. Usher received this award in recognition of a series of papers in which he developed a new tool, called “boundary depth”, for understanding the intricacies of the group of Hamiltonian diffeomorphisms. This work has led to new results and insights about the existence of periodic orbits in Hamiltonian dynamics. Professor Sybilla Beckmann: Mary P. Dolciani Award Hot off the presses: we have recently received word that Professor Sybilla Beckmann will be awarded the Mathematics Association of America’s Mary P. Dolciani Award next August at MathFest in Washington D.C. The award is given in recognition of Dr. Beckmann’s contributions to the mathematical education of K-16 students. Faculty Promotions Dr. Jinzhi Tie was promoted in July 2014 to the rank of professor. Dr. Tie is a widely recognized expert on the harmonic analysis of nilpotent Lie groups. He has an extensive body of work on the analysis of the sub-Laplacian on the Heisenberg group and other areas of Cauchy-Riemann geometry. Dr. Tie regularly teaches graduate courses in partial differential equations, complex analysis, and real analysis, as well as a broad spectrum of undergraduate courses. Dr. Miljenko Zabcic was promoted in July 2014 to the rank of senior lecturer. Dr. Zabcic has been a lecturer with our department since 1997. He teaches a variety of classes from pre-calculus to math major courses, such as modern algebra and complex geometry, impacting hundreds of students each year. He is famous among our students for the clarity of his lectures, his infectious enthusiasm, and his high standards. Data collected for his promotion dossier showed that students who take courses from Dr. Zabcic are far more likely to succeed in their next mathematics course than their peers. Certainly this is an impressive testimony to the effectiveness of his teaching. Alumni Updates Join the LinkedIn UGA Mathematics Department group to see more (and share your own news)!

In Memoriam I am very sad to report the passing of three of our former faculty members this past year. Kenneth Johnson was member of our department from 1977 until his retirement in 2006. His research in representation theory was deep, creative, and highly regarded. He was a wonderful colleague, serving a term as graduate coordinator and a term as associate department head over the years. His devotion as a teacher was highly appreciated by his students and his sense of humor was legendary. I can’t help but mention that Ken also shared a passion of mine in running. For many years he was a regular participant in the local racing scene. He continued running right up to the very late stages of his illness. Ray Kunze was a member of our department from 1983 to 1996. He was hired as department head and held that position until 1989. In many ways he shaped the department for years to come by hiring several of the faculty that are still at UGA. When he left UGA in 1996 he became department head at UC Irvine. Ray maintained a strong research program in representation theory. He was also well known for the linear algebra text book that he wrote with Kenneth Hoffman. David Penney was a member of our department from 1966 until his retirement in 2000. David was best known for his calculus and differential equations textbooks co-authored with C. Henry Edwards. He was a devoted teacher, winning several teaching awards over his career at UGA. Upcoming Events 21st Annual Cantrell Lectures, April 7-9 2015, will feature Benedict Gross from Harvard University. Visit our event page for further information. The 2015 Georgia Topology Conference will be held June 10-14, 2015. This year's conference focuses on various aspects of symplectic topology and dynamics. Elementary, analytic, and algorithmic number theory: Research inspired by the mathematics of Carl Pomerance will occur on June 9-11, 2015. See the event page for more information.
