## Aerospace and Physics

Hello and welcome to my online CV, and portal of shameless self-promotion! I am a physicist and aerospace engineer working for the Aerospace Corporation in El Segundo, CA. My day-to-day work involves analyzing rocket launches and orbital trajectories. It's fun work and I love what I do.

Previously I was a researcher in particle physics, focusing on the phenomenology of dark matter and extensions to the Standard Model of particle physics. I made my bones at Reed College (BA Physics), University of Hawaii (MS, PhD Physics), and University of Arizona (MS Aerospace Engineering).

Many of the controllers I have studied and developed involved fractional derivative and integral feedback terms to shape the system trajectory; the fractional calculus generalizes standard integer-order calculus in the sense that operations such as differentiation and integration can be taken to a non-integer order, e.g., $$D^{1}f(x) ~ \rightarrow ~ D^{1/2} f(x)$$ Thus the order of these fractional operators becomes a new tunable parameter which can be used to more freely shape the trajectory of a controlled system.
