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!

Hoa Dinh

Dr. Hoa Dinh
Assistant 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.

weasterling38952@troy.edu

I have a Bachelor's in Mathematics and a Master's in Mathematics Education both from Troy University. I became full time at the Troy campus in the fall of 2010 and teach general studies mathematics courses. Prior to moving to Troy, I taught junior high/high school mathematics in Autauga and Elmore counties while also teaching adjunct courses at Troy Montgomery and Faulkner University.

Reiff Lafleur

Dr. Reiff Lafleur
Associate Professor
334-983-6556 x1395
rlafleur@troy.edu

I earned my M.S. in Mathematics at the University of Rhode Island in 1986.  I earned my Ph.D. in Mathematics at the University of Connecticut in 1997.  I do not have a B.S.  When I was at the University of Rhode Island they had a program for early admission to graduate school.  You could be admitted if you had "an outstanding record based on grades, recommendations and Graduate Record Exam (standardized test) scores".  If there was one thing I was always good at it was standardized tests.  I did well enough that I was accepted for early admission to graduate school, without getting a Bachelor's Degree.  My thesis was in Abstract Algebra.  I love Abstract Algebra.  But I like to think of myself as a jack of all trades.  I like to look at a variety of different types of math and science.  In my job at Troy University Dothan Campus, I get to teach a wide variety of classes, which I enjoy.  In addition to my mathematics classes, the University of Alabama has a distance program in Mechanical Engineering.  I was a Mechanical Engineering major many years ago for one year.  I took Statics, Dynamics, and Strength of Materials.  I enjoy helping engineering students with their coursework, in spite of the fact that I have not taken these classes.  The classes are mainly applied Physics and Math.  I also enjoy helping students study for the Praxis test in Mathematics.  I enjoy trying to figure things out.  I enjoy doing problems.

kroblee@troy.edu

I received degrees from the University of Alabama (B.S.) and Auburn University (M.S., Ph.D.).  My primary research area is Graph Theory.  I enjoy mentoring student research projects, and advising our Mathematics Club and chapter of the national mathematics honor society. I primarily teach mathematics major and minor courses.

Dr. Pat Rossi

Dr. Pat Rossi
Professor
334-670-3588
prossi@troy.edu
http://www.pat-rossi.com/

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. 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.
