Rainey Lyons | Karlstad University

Research

I am broadly interested in applied mathematics, but I have specific interests in mathematical modeling, differential equations, measure valued PDEs, numerical analysis,  dynamical systems,  optimization, etc.

I will gladly work on any interesting mathematical problem with applications to the natural sciences.

Teaching

I have taught the following courses:

<ul>
<li>College Algebra (University of Louisiana at Lafayette (UL)),</li>
<li>Precalculus Algebra (UL),</li>
<li>Precalculus Trigonometry (UL),</li>
<li>Survey of Calculus (UL),</li>
<li>Elementary Linear Algebra (UL).</li>
</ul>
