Professor Rassi joined Olivet's full-time faculty in 2015. He has a strong interest in preparing teachers for math education. "I'm very excited about math education!" he says. "I'm a Dan Meyer fan. I think teaching math is one of the most rewarding and challenging careers." Professor Rassi is currently pursuing his PhD in Math Education at Illinois State University.

His professional experience includes nine years of teaching pre-algebra through calculus, as well as dual credit finite and statistics at the high school level. He has also served as a consultant/workshop presenter for the Iroquois-Kankakee Regional Office of Education.

As a presenter for several professional conferences, Professor Rassi has researched and spoken on a variety of topics, including "Can You Build the Best Boat?" and "Gain Mathematical Power in Calculus through Multiple Representations." In 2014, one of his students named him as her Most Influential Teacher as part of her award through the U.S. Presidential Scholars Program. He is a member of the National Council of Teachers of Mathematics (NCTM), Association of Mathematics Teacher Educators (AMTE) and North American Chapter of the International Group for the Psychology of Mathematics Education (PME-NA).

All is not classroom and research in Professor Rassi's life, however. In his leisure time, he enjoys reading, singing, working on home construction projects and playing board games. The beauty and adventure of the outdoors often call to him, and he is a hiking and camping enthusiast. During his Bible study time, he especially appreciates the book of Romans.

He and his wife, Janelle, are the parents of four children: Kyla, Layna, Trevin and Treyson. Spending time with his family is one of his greatest pleasures.

Dr. Lyle joined Olivet's full-time faculty in 2015. He enjoys teaching a variety of mathematics courses and considers graph theory to be his favorite area of study. Before coming to Olivet, he was a professor at the University of Southern Mississippi for seven years.

His professional accomplishments include the publication of 10 journal articles in the area of graph theory and computer science, in addition to other conference and workshop proceedings. His recent publications include "A Structural Approach for Independent Domination of Regular Graphs," published by Graphs and Combinatorics in 2015, and "A Note on Independent Sets in Graphs with Large Minimum Degree and Small Cliques," published by the Electronic Journal of Combinatorics in 2014.

He and his wife, Tracy, are the parents of four children: Emily, Alex, Austin, and Eli. One of the ways he enjoys relaxing is playing the harmonica.

Dr. Hathaway joined the mathematics department in 1989 and currently serves as chair. He has taught a variety of mathematics courses, including statistics; probability; linear algebra; discrete, finite, and liberal arts mathematics; and calculus.

In addition to his teaching responsibilities, Dr. Hathaway has been active in research with a dozen publications, including the textbook that is used for Olivet's mathematics for the liberal arts course. He is currently working on a book of devotionals related to mathematics.

He has given many professional talks, most at national meetings of the Mathematical Association of America. He has also served for many years as a table leader and question leader for AP calculus. Recently, he has served as the chair-elect, chair (two years) and past chair (two years) of the ISMAA (Illinois Section of the Mathematical Association of America).

His involvement with students has included supervising summer research experiences for eight students. He is also the organizer of the Math Club, which gives students and faculty a chance to get together for food and fun with mathematics.

Because of his positive involvement with students, Dr. Hathaway received the Second Mile Award in 2004. This is a student nominated award. In 2011, he received Olivet's Samuel L. Mayhugh Award for Scholarly Excellence.

When he's not busy with mathematics, you may find him with his wife, Heather, and their three adult children; riding his bike; or organizing his 1800-piece puzzle collection.

Dr. Green arrived on campus in 1993. His doctoral dissertation was in Real Analysis, but he now serves as the department's financial mathematics specialist in conjunction with the Actuarial Science major. He has published research in PRIMUS and Mathematics Teaching in Middle School.

He is the chief writer of the River Valley Mathematics Competition and writes questions for other area high school mathematics competitions. His areas of interest include the use of technology in Mathematics Education, Real Analysis and Actuarial Science.

His wife, Karen, is an Olivet alumna. They have an adult son, Mark, and a daughter, Julisa.

Associate Professor

Ph.D., 2009, Northeastern University
M.S., 2005, Northeastern University 
B.A., 2003, Point Loma Nazarene University 

Dr. Brown joined Olivet's faculty as a full-time professor in 2009. He currently teaches calculus, linear algebra, abstract algebra, number theory and differential equations.

For the 2010-2011 academic year, he was a Project NExT fellow. This is a professional development program for new or recent Ph.D.s in the mathematical sciences, sponsored by the Mathematical Association of America. It addresses all aspects of an academic career, with an emphasis on the teaching and learning of mathematics, and provides participants with a network of peers and mentors as they assume these responsibilities.

Before teaching at ONU, he was a graduate assistant at Northeastern University. There, he was named Outstanding Teacher of First Year Engineering Students in 2007. He also collaborated on a published textbook for graduate students studying algebraic geometry, which was the focal point of his doctoral research.

While an undergraduate student at Point Loma, he served on a three-week mission trip to Rwanda. He also helped with a weekly feeding program in downtown San Diego. While studying at Northeastern in Boston, he volunteered with a poverty advocacy group, advocating on behalf of poor families facing difficult financial situations.

He enjoys spending time with his wife, Jody; their sons, Owen, Evan, and Callen; and their daughter, Islyn. For relaxation, he likes watching football, kayaking, playing guitar and listening to Bob Dylan.

If you're a baseball fan, you might recognize his voice, too. He's the announcer for Tiger baseball at ONU.

Dr. Boros joined Olivet's faculty in 2012 after teaching at Michigan State University for seven years. He teaches calculus, differential equations, linear algebra, numerical analysis, real analysis and Senior Seminar.

His research interests lie in sharply estimating Fourier multiplier operators using techniques in harmonic analysis. His research has been published in Advances in Mathematics Journal, Indiana University Mathematics Journal, Comptes Rendus Mathématique and Journal de Mathématiques Pures et Appliquées. He has presented his work on harmonic analysis for the American Mathematics Society and Mathematical Association of America annual meetings, INRIA Sophia Antipolis Méditerranée (France), Instituto Matemáticas Universidad Sevilla (Spain), Institut Mittag – Leffler (Sweden), and Fields Institute (Canada).

While at Michigan State, Dr. Boros received the Senior Graduate Teaching Award. His teaching assignments included serving as the Charles Drew Science Scholars mathematics instructor, the Math Enrichment for Student Athletes instructor, and the Engineering and Science Summer Academy "Bridge Program" mathematics instructor. Much of his focus was working with underrepresented students in the STEM fields, who began in remedial math, yet had career aspirations that required graduate or professional school.

He is a member of the Mathematical Association of America, American Mathematical Society and Association of Christians in the Mathematical Sciences. For the 2012-2013 academic year, he was a Project NExT fellow.

Tending toward the eclectic, he enjoys traveling and eating ethnic foods from other countries. When he's off campus, you might find him watching one of his favorite international or independent films.

Dr. Boros and his wife, Lindsey, are the parents of Elizabeth and Katelyn, and family time is one of his top priorities.
