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).

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.

Joining Olivet's full-time faculty in 2013, Dr. Cheng currently teaches courses in calculus, foundations and differential equations. She taught at Indiana University-Kokomo before coming to Olivet.

In 2012, she presented her graduate work on "Chevron structures in liquid crystal films" to the American Mathematical Society Special Session at the Joint Mathematics Meetings. Her research focused on analytically exploring the effects of temperature change on the liquid crystal structures from a mathematical point of view.

Outside of the classroom and away from the computer, Dr. Cheng enjoys music and worship. She has set a goal to learn to play the piano so that she can play hymns for personal and family devotion times. She also enjoys doing aerobics and exploring the outdoors.

She is a native of China, and her husband, Peter, is a native of Taiwan. They met through the Chinese Christian Church while they were students at Purdue. Their leisure activities include travel, watching "feel good" movies, finding the best Asian food restaurants and fellowshipping with friends. With Peter as her personal coach, she is also learning to play tennis.
