Work Experience
In the summer of 2015, I went to NASA Research to do some top secret stuff.
In the past, I've have worked in statistical consulting at the University of Michigan (CSCAR), and have interned at a finance firm.

And more
I enjoy playing games that involve bouncy spheres, weightlifting, reading books, cooking.
Fun fact: I served 2 years in the military at the Joint Security Area, at the border of North/South Korea.
