Biography
Ned Nedialkov was born and raised in Bulgaria. He received M.Sc. (1995) and Ph.D. (1999) degrees in Computer Science at the University of Toronto, and has been with the Department of Computing and Software at McMaster University since 1999. He was a longterm visitor
during the Thematic
Year on Numerical and Computational Challenges in Science and Engineering at the Fields Institute 200102, spent a sabbatical year at the
Center for Applied Scientific Computing at the Lawrence Livermore National Laboratory in 200506, and was a
guest of the Arénaire project at École Normale Supérieure de Lyon in the summer of 2008.
His research is in the general area of scientific computing and mathematical software with emphasis on interval
numerical methods for differential equations and numerical methods for differentialalgebraic equations. He is the
author of the VNODE and VNODELP packages for computing rigorous bounds on solutions in initialvalue problems for
ordinary differential equations, and the DAETS package for solving highindex differential algebraic equations.
PhD positions
I have two industriallyfunded PhD positions. The research will
be on mixedprecision numerical algorithms and highperformance
computing to accelerate the performance of various solvers. A substantial component of the work is the
implementation of such algorithms and incorporating them into industrialstrength codes. I seek candidates with a
strong background in applied mathematics and computing. Experience in C/C++, software design and development,
software optimizations for highperformance, and writing parallel programs is highly desirable.
