List of Famous people born on March 25th

Richard Alfred Tapia is an American mathematician and champion of under-represented minorities in the sciences. In recognition of his broad contributions, in 2005, Tapia was named "University Professor" at Rice University in Houston, Texas, the University's highest academic title. The honor has been bestowed on only six professors in Rice's one-hundred-five-year history. On September 28, 2011, President Barack Obama announced that Tapia was among twelve scientists to be awarded the National Medal of Science, the top award the United States offers its researchers. Tapia is currently the Maxfield and Oshman Professor of Engineering; Associate Director of Graduate Studies, Office of Research and Graduate Studies; and Director of the Center for Excellence and Equity in Education at Rice University.

Jung Chang is a Chinese-born British writer now living in London, best known for her family autobiography Wild Swans, selling over 10 million copies worldwide but banned in the People's Republic of China.

Henri Berestycki is a French mathematician who obtained his PhD from Université Paris VI – Université Pierre et Marie Curie in 1975. His Dissertation was titled Contributions à l'étude des problèmes elliptiques non linéaires, and his doctoral advisor was Haim Brezis. He was an L.E. Dickson Instructor in Mathematics at the University of Chicago from 1975–77, after which he returned to France to continue his research. He has made many contributions in nonlinear analysis, ranging from nonlinear elliptic equations, hamiltonian systems, spectral theory of elliptic operators, and with applications to the description of mathematical modelling of fluid mechanics and combustion. His current research interests include the mathematical modelling of financial markets, mathematical models in biology and especially in ecology, and modelling in social sciences. For these latter topics, he obtained an ERC Advanced grant in 2012.

Robert Joseph Birgeneau is a Canadian-American physicist and university administrator. He was the ninth chancellor of the University of California, Berkeley from 2004-13, and the fourteenth president of the University of Toronto from 2000-04.

Yuen-Ron Shen is a Chinese physicist. He is a professor emeritus of physics at the University of California, Berkeley, known for his work on non-linear optics. He was born in Shanghai and graduated from National Taiwan University. He received his Ph.D. in Applied Physics from Harvard under physicist and Nobel Laureate Nicolaas Bloembergen in 1963, and joined the department of physics at Berkeley in 1964. In the early years, Shen was probably best known for his work on self-focusing and filament propagation of laser beams in materials. These fundamental studies enabled the creation of ultrafast supercontinuum light sources. In the 1970s and 1980s, he collaborated with Yuan T. Lee on the study of multiphoton dissociation of molecular clusters. The molecular-beam photofragmentation translational spectroscopy that they developed has clarified much of the initial confusion concerning the dynamics of infrared multiphoton dissociation processes. In the 1980s and 1990s, Shen developed various nonlinear optics methods for the study of material surfaces and interfaces. Among these techniques, second-harmonic generation and sum frequency generation spectroscopy are best known and now widely used by scientists from various fields. He has collaborated with Gabor Somorjai on the use of the technique of Sum Frequency Generation Spectroscopy to study catalyst surfaces. He is the author of the book The Principles of Nonlinear Optics. Shen belongs to the prolific J. J. Thomson academic lineage tree. Currently, Shen works in U. C. Berkeley and Fudan University in Shanghai.

Hermann Flaschka was an Austrian-American mathematical physicist and Professor of Mathematics at the University of Arizona, known for his important contributions in completely integrable systems.
