Yury Grabovsky is a professor at the Department of Mathematics at Temple University, where his research interests include the calculus of variations on the mathematics side and continuum mechanics on the physics side. His latest work was on the mathematical theory of composite materials, the buckling of slender bodies, such as plates, rods, and shells, and understanding the stability of equilibrium configurations with phase boundaries in nonlinear elasticity. After graduating with a PhD from the Courant Institute of Mathematical Sciences, New York University, Yury spent a year as a postdoc at the Center for Nonlinear Analysis at Carnegie Mellon University, and three years as a Wylie Instructor at the University of Utah. In 1999 he was hired as a tenure-track Assistant Professor by Temple University. Yury enjoys teaching and performing research with students. His webpage on using continued fractions in the design of calendar systems routinely draws the attention of media every leap year. It has been translated into Portuguese and published in a journal for mathematics schoolteachers Educação e Matemática.
