COLLEGE STATION --

Two Texas A&M University mathematicians have earned selection to the 2017 class of American Mathematical Society (AMS) Fellows in recognition of their international excellence in mathematical science and service.Texas A&M professors Yalchin Efendiev and Joseph M. Landsberg are among 65 mathematical scientists worldwide honored with selection to this year's class -- announced November 1 by the society -- in the program's fifth year.

Efendiev was cited "for contributions to the field of multiscale finite-element methods with applications to porous-media fluid flow," while Landsberg was cited "for contributions to differential geometry, geometry of projective varieties, representation theory, and complexity theory."

The prestigious designation recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication and utilization of mathematics. The AMS Fellows Program seeks to create an enlarged class of mathematicians recognized by their peers as distinguished for their contributions to the profession and to honor excellence.

"It's my pleasure to congratulate the members of the 2017 class of AMS Fellows on their outstanding accomplishments and to thank them for their contributions to mathematics and their leadership," said AMS President Robert L. Bryant. "I look forward to working with them in service to our mathematical community."

Efendiev, a leading expert in numerical and computational mathematics and co-holder of the Richard E. Ewing ExxonMobil Chair in Computational Science, has been a member of the Texas A&M Mathematics faculty since 2001. He received his doctorate in applied mathematics from the California Institute of Technology (1999), where he earned the W.P. Carey Prize for outstanding thesis work in applied mathematics. He serves as director of the Institute for Scientific Computation (ISC) and a co-principal investigator in the Institute for Applied Mathematics and Computational Science (IAMCS), one of four international interdisciplinary scientific research centers established in 2008 by King Abdullah University of Science and Technology (KAUST) in Saudi Arabia to initiate collaborative research on targeted problems facing Saudi Arabia and the world.

Efendiev's world-respected research focuses on numerical analysis and scientific computation with applications to porous media fluid flow, primarily ground water and oil recovery modeling. He is a member of the American Mathematical Society (AMS), the Society for Industrial and Applied Mathematics (SIAM) and the Society of Petroleum Engineers (SPE). In addition to authoring more than 125 peer-reviewed publications, he is co-author of a book,

An invited speaker at the International Congress of Mathematicians 2014 and a plenary speaker at the International Society of Porous Media 2015, Efendiev has been recognized with several major awards, including the Alexander von Humboldt Foundation's Fraunhofer-Bessel Research Award (2011) and as a Quantum Reservoir Impact (QRI) Scholar (2011). His overall research program has a strong track record of funding support from both federal and industry sources, including the National Science Foundation, the United States Department of Energy, the Air Force Office of Scientific Research, Chevron and SINOPEC.

Landsberg, who joined the Texas A&M Mathematics faculty in 2004, received his doctorate in mathematics from Duke University in 1990 after earning combined bachelor's and master's of science degrees in mathematics with honors from Brown University in 1986. He was a Hans Rademacher Instructor and National Science Foundation postdoctoral fellow at the University of Pennsylvania (1990-1992, 1993-1994) as well as a visiting member of and NSF postdoctoral fellow at Princeton University's Institute for Advanced Study during the year in between. Prior to coming to Texas A&M, Landsberg held visiting professor assignments at a number of prestigious institutions, including Georgia Institute of Technology, Harvard University and Columbia University.

Landsberg's research areas include geometry of tensors and applications, exterior differential systems and geometry of projective varieties. His current work focuses on applications of algebraic geometry, differential geometry and representation theory to complexity theory. His research has been regularly funded by the NSF since 1990.

In fall 2014, Landsberg served as Chancellor's Professor at the Simons Institute for the Theory of Computing at the University of California, Berkeley, where he co-organized a semester-long program on algorithms and complexity in algebraic geometry and also gave a course on geometry and complexity theory. This fall at Texas A&M, Landsberg is teaching a graduate course on the subject while also organizing and/or co-organizing two weekly events in Blocker -- a working seminar for postdoctoral and graduate students each Tuesday as well as a geometry seminar every Friday.

Landsberg has authored three books:

Founded in 1888 to further mathematical research and scholarship, the 30,000-member AMS fulfills its mission through programs and services that promote mathematical research and its uses, strengthen mathematical education, and foster awareness and appreciation of mathematics and its connections to other disciplines and everyday life.

Efendiev and Landsberg join 13 other Texas A&M Mathematics faculty who have achieved AMS Fellow distinction. Harold P. Boas, Ronald A. DeVore, Ronald G. Douglas, Rostislav Grigorchuk, William B. Johnson, Peter Kuchment, Gilles Pisier, Frank Sottile, Emil J. Straube, Clarence Wilkerson and Guoliang Yu each were among the inaugural class named in 2013, followed by David Larson in 2015 and Thomas Schlumprecht in 2016.
