About
My research interests are in ion particle acceleration and transport. I am particularly interested in energetic particle entrance and effect on both the terrestrial and gas giant magnetospheres. I also am interested in developing next-generation particle instruments that can be miniaturized for use on CubeSats while still providing top-of-the-line mass and energy resolution.
In my personal time I enjoy playing with my 2 large dogs, spending time outdoors, baking, and reading.
Please contact me for further information about my research or interest in collaboration.
