Texas A&M University mathematicians Alexei Poltoratski and J. Maurice Rojas have earned selection to the 2019 class of American Mathematical Society (AMS) Fellows in recognition of their international excellence in mathematical science and service.

Poltoratski and Rojas are among 65 mathematical scientists worldwide honored with selection to this year's class -- announced November 1 by the society -- in the program's seventh year.

Poltoratski was cited "for contributions to harmonic analysis, operator and spectral theory."

Rojas was cited "for contributions to algorithmic algebraic geometry, complexity theory, and scientific computation, and mentoring of student research at all levels."

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.

Poltoratski joined the Texas A&M Department of Mathematics faculty in 1998 after receiving both his masters of science and doctorate in mathematics from the California Institute of Technology in 1995. He completed a postdoctoral fellowship at the University of California, Berkeley, Mathematical Sciences Research Institute and was a C.L.E. Moore Instructor at the Massachusetts Institute of Technology prior to coming to Texas A&M, where his research focuses on complex and harmonic analysis, singular integrals and spectral problems. Poltoratski was an invited speaker at the International Congress of Mathematicians 2018, a coveted honor reserved only for the top mathematicians worldwide. He was among the 20 experts featured within the Analysis and Operator Algebras section, one of 19 within the overall ICM 2018 scientific program. Poltoratski also served as honorary editor in 2015 for the 150th anniversary issue of the oldest Russian mathematics journal, Mat. Sbornik. In addition, he was a Conference Board of the Mathematical Sciences (CBMS) lecturer in 2013 as well as a distinguished visiting professor at Brown University in 2015-2016.

Rojas joined the Texas A&M Mathematics faculty in 2001 and since 2013 also has held a courtesy appointment in the Department of Computer Science and Engineering. He earned masters degrees in both mathematics and computer science (1991) as well as a Ph.D. in applied mathematics (1995) from the University of California, Berkeley. Rojas completed postdoctoral study at the Mathematical Sciences Research Institute, MIT and City University of Hong Kong and then held visiting positions at Johns Hopkins University, the Institute for Mathematics and its Applications, and Sandia National Laboratories prior to coming to Texas A&M. His research in algebraic geometry and algorithmic complexity is extensively published and funded primarily by the National Science Foundation, including through a 2004 Faculty Early Career Development (CAREER) Award. Rojas is equally respected as one of the department's best teachers and as a quality mentor for both graduate and undergraduate students, receiving a 2018 College of Science Undergraduate Research Mentoring Award in recognition of his important investment in the future of scientific research. As a key leader of Texas A&M Mathematics' NSF-funded Research Experiences for Undergraduates (REU) program, he has helped to secure back-to-back three-year grants to fund the program through 2021. In summer 2017, Rojas also was invited to be research director of the prestigious Mathematical Sciences Research Institute Undergraduate Program (MSRI-UP), working with students from under-represented groups. In addition, he boasts decades of extensive reviewer and referee experience across publications, discipines and continents.

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.

Poltoratski and Rojas join 18 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, Thomas Schlumprecht in 2016, Yalchin Efendiev and Joseph Landsberg in 2017 and Roger Smith, Sarah Witherspoon and Catherine Yan in 2018.
