User:Peter Kagey

I graduated from Oregon State University in June 2014 with a B.S. in Mathematics. From December 2014 until August 2017, I worked as a back end web engineer at a health technology company. From August 2017–July 2022, I was in a Ph.D. program at the University of Southern California. From 2022–2024, I was visiting assistant professor of mathematics at Harvey Mudd College. I am currently an assistant professor in the department of Mathematics and Statistics at Cal Poly Pomona.

Most of the scripts that I have written to generate OEIS sequences can be found on my OEIS Github Repository. I work mostly in Haskell.
