## Introduction

I'm an Associate Professor here at the Department of Mathematics of the University of Tennessee Knoxville. My area is Algebraic Number Theory and Arithmetic Geometry.

Here is a picture of me. But be warned, after you see it, you can't unsee it!

## To my current students (Spring 2021)

Go to: FYS 129 - "Mathematics and Finances", Math 397 - "Junior Honors Seminar", Math 499 - "Applied and Computational Number Theory".

Notes for the **Project GRAD Summer Institute 2009**: "A Gentle Introduction to
Number Theory and
Cryptography".

Here is a spreadsheet (Open Document format, MS Excel format) that can be used to computed interest, final value with interest and payments, calculate value of payments, and how long to pay off or save a specific value. You will need to read the instructions to use it.

Every time you go outside, go slowly

Looking for a piece of mind, don't lose your ground

Every time you lose your ground, fall softly

You become what you do, become what you feel

Become what you need, then softly fall

Stand up, don't you crawl, you have to be only reason you go that slowly
