The Department of Mathematics and Statistics is a community of scholars committed to excellence in research and instruction. We offer a comprehensive set of curricula in our disciplines, from introductory-level general education courses to doctoral dissertation direction and postdoctoral mentoring. Undergraduate majors enjoy a broad array of options through which they can earn the bachelor's degree, and can also apply to participate in summer research activities. The Department's Ph.D. program appears among the top public graduate programs in the recent National Research Council rankings. The M.S. programs in both Applied Mathematics and Statistics contribute to an important pipeline of professionally trained students who enter the high-technology industrial sector.

### October 2015

On October 15, 2015 Professor Matthew Dobson gave a talk titled “Derivation and Simulation of Nonequilibrium Langevin Dynamics” at UMass Dartmouth.

On October 23, 2015 Professor Richard S. Ellis gave an invited talk for the UMass Amherst Contemplative Pedagogy Working Group at UMass Amherst. The title of his talk was “Contemplative Pedagogy for Establishing Presence and Healing Stress”.

On October 3–4, 2015 Professor Nestor Guillen participated in and gave a talk at the AMS Special Session on Nonlocal Diffusions in Chicago, IL. On October 20 he gave a talk at the PDE seminar in the Department of Mathematics at Georgia Tech in Atlanta, GA. Finally, on October 24–25 he participated in and gave a talk at the AMS Special Session on Recent Developments in Nonlinear Partial Differential Equations in Fullerton, CA.

On October 13, 2015 Visiting Assistant Professor Robin Koytcheff gave a talk in the Tulane University Topology Seminar titled “A Colored Operad for String Link Infection”.

Professor Michael Lavine gave the following three talks: “Approximately Exact Calculations for Linear Mixed Models” in the Department of Biophysics at University of Minnesota on September 30, 2015; “On Likelihood” in the Department of Statistics at University of Minnesota on October 1; and “On Likelihood” at Duke University on October 31.He also attended the ASA Workshop on P-values on October 19–20.

During the period October 9–11, 2015, the Department hosted a workshop at UMass Amherst titled “Workshop on Springer Theory and Related Topics” and focusing on current trends in representation theory. More than 60 graduate students and researchers from across the country attended. The workshop was supported by a $25,000 grant from the National Science Foundation and was organized by Professors Alexei Oblomkov and Eric Sommers, together with Pramod Achar from LSU. The conference webpage can be viewed at https://www.math.lsu.edu/~pramod/UMass2015/.

Professor Eric Sommers, the Co-Director of the Actuarial Program in the Department, reports on the following activity. The Actuarial Program along with the UMass Actuarial Club held the 7th annual Actuarial Career Fair on October 5, 2015 to help students secure internships and full-time positions in the industry. The fair was made possible by generous donations from Robert Pollack ('54), Hanover, and the Actuaries’ Club of Hartford & Springfield. The following eleven companies attended: Aetna, Aon Hewitt, Hanover, The Hartford, Liberty Mutual, MassMutual, Mercer, Prudential, Sun Life, Travelers, and Unum. More than 90 students from the Five Colleges attended. Carl Kruglak ('87) and James Willwerth ('03) from Sun Life gave a presentation on entering the actuarial field. Of the 27 company representatives, 17 were UMass alumni and 4 were alumnae from Mt. Holyoke and Amherst Colleges. The fair was a big success, with many companies noting it was the biggest turnout that they could remember! The Actuarial Program is thriving with more 100 students selecting the actuarial concentration within the major and with the appointment of a new advisory board for the upcoming year. The program was invited to observe the Travelers CASE competition, at which Professor Erin Conlon represented UMass.

On October 13, 2015 Professor Hongkun Zhang gave a seminar talk in the Department of Mathematics at Aix-Marseille University in France on “Statistical Properties of Billiards”. The NSF conference proposal on “Statistical Properties of Hyperbolic Systems” that she submitted in October has been recommended for funding. The conference will be held at the Chinese Academy of Science during the period August 1–5, 2016. Hongkun was also awarded the Visiting Scholar Fellowship by University of Toulon, France, for the period of September–October, 2015. This fellowship will cover her living expenses for her visit to the University de Toulon and Centre de Physique Theorique in Luminy France.
