Dr. Traylor is the founder and lead mathematician at the Math Citadel, and a Research Assistant Professor at Marquette University. She is a former Senior Research Scientist in Mathematics and Analytics for Dell EMC, producing 6 patents during her 2 year tenure. She has also worked for Lockheed Martin Aeronautics as a DBA and quality control analyst. Her academic experience includes working as an instructor at 4 different institutions throughout the US, as well as pure and applied mathematics research focusing on probability theory, queueing, and reliability theory. She has given numerous lectures, webinars, seminars, and conference talks across the country in both academic settings and industrial conferences. Beyond her experience in the technology, aerospace, and manufacturing sectors, she has university training and background in logistics, operations research, and chemistry.

Bio
 B.S. Mathematics, Minor Chemistry, University of Texas at Arlington, 2013
Jason Hathcock studied mathematics and chemistry at the University of Texas at Arlington, receiving an Honors B.S. in Mathematics with a minor in Chemistry. He continued to study mathematics under Dr. Andrzej Korzeniowski at the graduate level, with an emphasis in applied probability. He produces the photographs, and musical numbers for the videos of the Research Cortex, and assists Dr. Traylor in her research endeavors.
His hobbies include composition for the guitar, beautiful typesetting, and quietly critiquing film.

Research Interests and Specializations
Bio
Matt Kukla is an undergraduate mathematics student at the University of Maryland, interested in (higher) category theory, algebraic geometry/topology, and formal logic, as well as applications of these to other fields such as computer science, physics, and philosophy. He previously interned at Patton Electronics, where he assisted in developing a Linuxbased operating systems for a prototype VDSL router.
When not thinking about mathematics, he can be found befriending the local avian life or trifling with electronics.
