General Information
Before drifting out of electrical engineering into mathematics, I worked for Trimble Navigation Limited and designed firmware for navigation, tracking, data collection and timing. After receiving my doctorate from University of Illinois at Urbana–Champaign and completing my postdoctoral research at University of Rochester, I moved to The University of Tennessee, Chattanooga in 2011.
Research Interests
 Number theory
 Probability
Teaching
In Fall 2020, I will be teaching
 MATH 4300 Mathematics of Interest
 MATH 5250 Modern Algebra I
Editorial Board
I am happy to communicate high quality papers in number theory and probability to Punjab University Journal of Mathematics, where I currently serve as Associate Editor.
