  • Portrait of Joseph Grenier

Joseph Grenier

In 2007 I joined the Marine Corps and trained as an Arabic Linguist. After five years of service I was honorably discharged as a Sergeant of Marines. I then went on to spend a few months in Mwanza, Tanzania, as a volunteer teaching high school math and physics. Upon returning home I took up a summer job doing sports photography throughout the state of Florida.

In fall of 2013 I began teaching high school and started my masters program at Florida Gulf Coast University right by where I grew up. I stopped teaching after a year and by July of 2015 I received my MSc. I headed to Louisiana State University in August of 2015 and spent the next four years working on my PhD.

I have lived now lived in nine states and two (other) countries. I have visited every state but Hawaii, most of lower Canada, and five other countries. I travel a LOT and have driven the entire lengths of I10, I20, I40, I90, I5, I75, and I95.

Outside of math and physics, I read extensively books on philosophy, metaphysics, and whatever topic peaks my interest at the moment. I read at least a book a month and my current favorite author is Brandon Sanderson. I am a vegetarian and I cook at least one full meal a day.

Tldr; I love life and try to do everything
