My name is Omar Richardson. I am a PhD candidate in applied mathematics at Karlstad University, Sweden under supervision of professor Adrian Muntean.

Because I think it is important that research is comprehensible and useful to everyone, I aim to make my contributions in science and programming publicly available as much as possible. With this blog, I intend to demonstrate what I am working on in an accessible way.

About my research

My research is focused on describing transport and interactions of populations. Simply put, I look at large groups of particles, which can represent anything from pedestrians to bacteria, and I try to express their behaviour in mathematical terms. If you are able to represent a situation in formulas or algorithms, it becomes a lot easier to analyse and predict. Most of my work is done in the context of crowd dynamics: the study of people in motion, interacting with each other and their environment. I did some work on evaluating evacuation strategies in buildings and large outdoor scenarios, and making new models that try to capture important elements in evacuation scenarios (like smoke and fire).

I deal with the numerical analysis of these systems, as well as tackling obstacles in the computationally demanding simulations. From the mathematical formulations I try to build simulations that capture the situations as accurate (and fast) as possible. This involves combining continuum systems with particle systems, which I researched in my MSc project, parallelising computations to increase scalability, and applying multiscale modelling techniques to compartmentalise transport and interaction.


I was born and raised in Nijmegen, The Netherlands. After high school, I moved to Eindhoven for my BSc and MSc degree in Applied Mathematics at the University of Technology Eindhoven. In August 2016, I moved to Karlstad, Sweden to start as a PhD student at Karlstad University in the field of applied mathematics.
