## 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:

- College Algebra (University of Louisiana at Lafayette (UL)),
- Precalculus Algebra (UL),
- Precalculus Trigonometry (UL),
- Survey of Calculus (UL),
- Elementary Linear Algebra (UL).

## Collaboration

My main collaborator at this time is **Adrian Muntean** here at Karlstad University. Some other collaborators include:

**Sander Hille**(Leiden University),**Emilio N. M. Cirillo**(Sapienza University of Rome),**Andrea Muntean**(Karlstad University),**Azmy S. Ackleh**(University of Louisiana at Lafayette),**Nicolas Saintier**(University of Buenos Aires),**Annette M Ostling**(University of Texas at Austin),**Ursula Trigos-Raczkowski**(University of Michigan).

## Bio

Originally from New Orleans, Louisiana, I attended the University of Louisiana at Lafayette for my Bachelor of Science in Mathematics (2016), Master's of Science in mathematics (2019), and Doctor of Philosophy in Mathematics (2021).
