Leslie Frederick Greengard (born 1957) is an American mathematician, physicist and computer scientist. [2] [3] He is co-inventor with Vladimir Rokhlin Jr. of the fast multipole method (FMM) in 1987, recognized as one of the top-ten algorithms of the 20th century. [2] [4]
Greengard was elected as a member of the National Academy of Engineering in 2006 for work on the development of algorithms and software for fast multipole methods.
Leslie Frederick Greengard [1] was born in 1957 in London, England, [5] but grew up in the United States in New York City, Boston, and New Haven. He holds a B.A. in mathematics from Wesleyan University (1979), an M.D. from the Yale School of Medicine (1987), and a Ph.D. in computer science from Yale University (1987). [2] [3]
From 2006 to 2011, Greengard was director of the Courant Institute of Mathematical Sciences, an independent division of the New York University (NYU) [3] [6] and is currently a professor of mathematics and computer science at Courant. He is also a professor at New York University Tandon School of Engineering [7] and the director of the Simons Center for Data Analysis. [8]
He formerly served as the Director at the Center for Computational Biology at the Flatiron Institute. As of October 2018 [update] , he has assumed the directorship of the new Center of Computational Mathematics at the Institute. [9]
He is the son of neuroscientist Paul Greengard and the nephew of Irene Kane, later known as Chris Chase, an actress, writer, and journalist. [10]
Paul Greengard was an American neuroscientist best known for his work on the molecular and cellular function of neurons. In 2000, Greengard, Arvid Carlsson and Eric Kandel were awarded the Nobel Prize for Physiology or Medicine for their discoveries concerning signal transduction in the nervous system. He was Vincent Astor Professor at Rockefeller University, and served on the Scientific Advisory Board of the Cure Alzheimer's Fund, as well as the Scientific Council of the Brain & Behavior Research Foundation. He was married to artist Ursula von Rydingsvard.
Baroness Ingrid Daubechies is a Belgian-American physicist and mathematician. She is best known for her work with wavelets in image compression.
The Courant Institute of Mathematical Sciences is the mathematics research school of New York University (NYU). Founded in 1935, it is named after Richard Courant, one of the founders of the Courant Institute and also a mathematics professor at New York University from 1936 to 1972, and serves as a center for research and advanced training in computer science and mathematics. It is located on Gould Plaza next to the Stern School of Business and the economics department of the College of Arts and Science.
The fast multipole method (FMM) is a numerical technique that was developed to speed up the calculation of long-ranged forces in the n-body problem. It does this by expanding the system Green's function using a multipole expansion, which allows one to group sources that lie close together and treat them as if they are a single source.
Charles Samuel Peskin is an American mathematician known for his work in the mathematical modeling of blood flow in the heart. Such calculations are useful in the design of artificial heart valves. From this work has emerged an original computational method for fluid-structure interaction that is now called the “immersed boundary method", which allows the coupling between deformable immersed structures and fluid flows to be handled in a computationally tractable way. With his students and colleagues, Peskin also has worked on mathematical models of such systems as the inner ear, arterial pulse, blood clotting, congenital heart disease, light adaptation in the retina, control of ovulation number, control of plasmid replication, molecular dynamics, and molecular motors.
Bradley K. Alpert is a computational scientist at NIST. He is probably best known for co-developing fast spherical filters. His fast spherical filters were critical in the construction of the most efficient three-dimensional fast multipole methods (FMMs) for solving the Helmholtz equation and Maxwell's equations. Other well-known work of his includes contributions to computational methods for time-domain wave propagation, quadratures for singular integrals, and multiwavelets.
Daniel Alan Spielman has been a professor of applied mathematics and computer science at Yale University since 2006. As of 2018, he is the Sterling Professor of Computer Science at Yale. He is also the Co-Director of the Yale Institute for Network Science, since its founding, and chair of the newly established Department of Statistics and Data Science.
Vladimir Rokhlin Jr. is a mathematician and professor of computer science and mathematics at Yale University. He is the co-inventor with Leslie Greengard of the fast multipole method (FMM) in 1985, recognised as one of the top-ten algorithms of the 20th century.
Subhash Khot is an Indian-American mathematician and theoretical computer scientist who is the Julius Silver Professor of Computer Science in the Courant Institute of Mathematical Sciences at New York University. Khot has contributed to the field of computational complexity, and is best known for his unique games conjecture.
The Presidential Young Investigator Award(PYI) was awarded by the National Science Foundation of the United States Federal Government. The program operated from 1984 to 1991, and was replaced by the NSF Young Investigator (NYI) Awards and Presidential Faculty Fellows (PFF) program. In 1995, the NSF Young Investigator program was subsumed into the NSF CAREER Awards program, and in 1996, the Presidential Faculty Fellows program was replaced by the PECASE program.
Weinan E is a Chinese mathematician. He is known for his pathbreaking work in applied mathematics and machine learning. His academic contributions include novel mathematical and computational results in stochastic differential equations; design of efficient algorithms to compute multiscale and multiphysics problems, particularly those arising in fluid dynamics and chemistry; and pioneering work on the application of deep learning techniques to scientific computing. In addition, he has worked on multiscale modeling and the study of rare events.
Michael J. Shelley is an American applied mathematician who works on the modeling and simulation of complex systems arising in physics and biology. This has included free-boundary problems in fluids and materials science, singularity formation in partial differential equations, modeling visual perception in the primary visual cortex, dynamics of complex and active fluids, cellular biophysics, and fluid-structure interaction problems such as the flapping of flags, stream-lining in nature, and flapping flight. He is also the co-founder and co-director of the Courant Institute's Applied Mathematics Lab.
