Achi Brandt, born in 1938 at Givat Brenner, is an Israeli mathematician whose work in numerical analysis has shaped modern computational science. Based primarily at the Weizmann Institute of Science, Brandt developed techniques that fundamentally altered how partial differential equations are solved, bridging the gap between theoretical mathematics and practical applications in hydrodynamics, statistical physics, and large-scale engineering computations.
Academic Foundations and Early Research
Brandt completed his doctoral studies at the Weizmann Institute of Science in 1965. Under the supervision of Joseph Gillis, he authored a thesis focused on numerical methods within the fields of hydrodynamics and magnetohydrodynamics. This early academic training established the technical trajectory for his subsequent contributions to multilevel mathematical methodologies.

The core of Brandt's reputation rests on his pioneering work with multigrid methods. These techniques utilize multiple levels of resolution to solve complex partial differential equations more efficiently than traditional single-grid approaches. His efforts expanded from foundational solvers to multiscale techniques, which proved essential for advancing research in statistical physics and various aspects of modern computational science.
Professional Appointments and Industry
Beyond his tenure at the Weizmann Institute, Brandt has held teaching positions at various international institutions. His academic affiliations include the Courant Institute of Mathematical Sciences and Stanford University. In the private sector, he served as a co-founder and chief scientist of VideoSurf, working alongside Lior Delgo, Eitan Sharon, and Shai Deljo. This venture received financial backing from Al Gore.
Recognition and Professional Standing
Brandt's contributions have been acknowledged through several honors. He received the Landau Prize in Mathematics in 1978 and the Rothschild Prize in Mathematics in 1990. In 2005, he was awarded the SIAM/ACM Prize in Computational Science and Engineering. Additionally, he has been recognized as a Fellow of the Society for Industrial and Applied Mathematics, an organization of which he remains an active member.
