## American mathematician / From Wikipedia, the free encyclopedia

**David Samuel Kinderlehrer** (October 23, 1941, Allentown, Pennsylvania)^{[1]} is an American mathematician, who works on partial differential equations and related mathematics applied to materials in biology and physics.

Kinderlehrer received in 1963 his bachelor's degree from MIT and in 1968 his Ph.D. from the University of California, Berkeley under Hans Lewy with thesis *Minimal surfaces whose boundaries contain spikes*.^{[2]} He became in 1968 an instructor and in 1975 a full professor at the University of Minnesota in Minneapolis. For the academic year 1971–1972 he was a visiting professor at the Scuola Normale Superiore di Pisa. In 2003 he became a professor at Carnegie Mellon University.

He works on partial differential equations, minimal surfaces, and variational inequalities, with mathematical applications to the microstructure of biological materials, to solid state physics, and to materials science, including crystalline microstructure, liquid crystals, molecular mechanisms of intracellular transport, and models of ion transport.

In 2002, he was the editor of the *Hans Lewy Selecta* published by Birkhäuser. His doctoral students include Irene Fonseca.

In 2012, Kinderlehrer was elected a Fellow of the American Mathematical Society.^{[3]} In 1974 in Vancouver he was an invited speaker (*Elliptic Variational Inequalities*) at the International Mathematical Congress.
