I grew up in Troy, Alabama and I am a proud alumnus of Troy University, having earned a B.S. in Mathematics and M.S.Ed. in Mathematics Education. I have taught adjunct for Troy University since 2003, both in the classroom and online. After teaching math for 22 years at the high school level, I returned to my alma mater in the fall of 2017 as a full-time Lecturer in the Department of Mathematics. I am proud to be a lifelong Trojan and to call Troy University my home.

amcarter@troy.edu
I grew up in Andalusia, Alabama and received both my bachelor's degree and my master's degree from Troy University. I have been teaching math for almost twenty years, but my years at Troy have been by far my favorite. I started at Troy as an adjunct instructor in the fall of 2009 and became a full-time lecturer in the fall of 2014. I primarily teach the math concepts courses for elementary education majors. I am passionate about teaching, I love my students, and I am proud to be Troy Trojan!
Dr. Hoa Dinh
Associate Professor

thdinh@troy.edu
Dr. Dinh received his PhD from Kazan Federal University (Russia) in 2010. He worked on trace and operator inequalities on von Neumann algebras and C*-algebras. Currently, his research focuses on topics of matrix theory, operator theory, functional analysis and applications. He works on the topic of inequalities involving matrices, trace, matrix functions, matrix means etc. and their applications in quantum information theory. His other mathematical interests include the quantum information theory, non-commutative algebraic geometry and matrix optimization.

I received my PhD from Auburn University, where my research was in the area of Homological Algebra. Currently, I teach the Calculus sequence, Calculus and its Applications, Computer Programming for Mathematics, Introduction to Advanced Mathematics, Linear Algebra, Numerical Analysis, the Real Analysis sequence, Number Theory, and History of Mathematics. In the past, I have also taught Differential Equations, Complex Analysis, the Mathematical Statistics sequence, Vector Calculus and Abstract Algebra; as well as all of the "core courses" in the undergraduate Electrical Engineering curriculum.
My current interests consist of perfecting my mathematical pedagogy and mentoring students in their research.
Dr. Vitaly Voloshin
Professor
Wallace D. Malone, Jr. Distinguished Faculty

vvoloshin@troy.edu
Dr. Voloshin worked at Moldova State University and at the Institute of Mathematics and Informatics of the Moldovan Academy of Sciences (Republic of Moldova, former Soviet Union) for many years, and moved to the United States in 2002. His research areas include graph and hypergraph coloring, theory, algorithms and applications. In 1993, he originated the direction of mixed hypergraph coloring, and there are now more than 200 scientific publications on the subject, including the author's Fields Institute Monograph. His research has been repeatedly supported by many scientific foundations of Italy, Germany, Canada, China, the United States, and other countries. He was the invited speaker of many major international conferences, held visiting positions at many universities throughout the world, and supervised and was consulted on many MS and PhD theses.
