I like physics because I've always been interested in learning how things work and understanding the way things are on a fundamental level.

I work in Dr. Paul Alsing's quantum information research group. My research focuses on characterizing quantum resources (e.g., entanglement) in high-dimensional quantum systems, and on experimental and theoretical quantum optics.

I received my Ph.D. August of (2015). See my contact info above and CV below if you're interested in collaborating in common fields of interest!

I also like to teach! Courses I've TA-ed for include:

- Freshman Newtonian Mechanics
- Lagrangian & Hamiltonian Mechanics
- Statistical Mechanics & Thermal physics

I've also given lectures on additional subjects:

- Negativity as a measure of entanglement
- Introduction to Information Theory
- Introduction to Compressive Sensing

(Beware, for they are handwritten!)

These slides go in a bit more depth into my research.
