ILYA LASHUK is a postdoctoral researcher at the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory (LLNL). He earned his Doctorate in Applied Mathematics from the University of Colorado Denver (Department of Mathematical Sciences). He also holds a Master of Science equivalent in Applied Mathematics from the Moscow State University in Russia, where he studied in the department of Computational Mathematics and Cybernetics. After completing his graduate studies, he worked for two years as a postdoctoral researcher at Georgia Institute of Technology before joining LLNL in 2010.

Ilya's research interests include multigrid methods, upscaling, fast multipole methods, and parallel computing.

Ilya's current project at LLNL is "Constrained energy minimization and Multigrid Methods".
