Roger Donaldson | PIMS - Pacific Institute for the Mathematical Sciences

Motorola Solutions

Roger Donaldson is a principal scientist working at Motorola Solutions, Inc. Roger has always enjoyed mathematics, but only seriously considered it as a career after meeting Brian Wetton of the UBC Mathematics Dept who at the time was doing an industrial collaboration with Ballard Power, a Burnaby fuel cell company, an early Mitacs project. Roger ultimately completed a Ph.D. at Caltech, worked at Google, and then returned to Vancouver to work as an industrial mathematics consultant.

Dr. Donaldson is one of the leaders of the PIMS CRG in High Dimensional Data Analysis.

We consider homogenization of the operator $u \mapsto -\text{div} (\sigma \nabla u)$, which is parameterized by symmetric $\sigma \in \real^{2\times 2}$ for the special case where the domain $\Omega \subset \real^2$. We refer to $\sigma$ as the...

This SCAIM lecture is more of a tutorial than a talk. I will present a simple Finite Element Method (FEM) code as a model for the more complex codes in common modern use. Code components include: mesh generation, matrix assembly, a linear solver, and...

A common experiment performed by web companies is the so-called A/B test, which compares two software designs assigning different interfaces or functionalities to two groups of randomly-selected users. Although it is usual to design these experiments...

The diversity of mathematics and roles of mathematicians in industry has expanded greatly over the last decade. The first part of this talk is a survey of work that I have done as an applied mathematician working in industry. Areas include modeling...
