About Paul Isihara
Dr. Paul Isihara joined Wheaton's faculty in 1987 after lecturing two years at Rochester Institute of Technology while completing his dissertation. He enjoys teaching students in many different areas and levels of college mathematics, and has been involved with undergraduate research in several different fields including atonal music theory, knot theory, cwatset theory, relational database and coding theory, wind turbines, dynamical systems in epidemiology, typhoon prediction, and community based operations research.
Dr. Isihara is also passionate about ministry, and has experience working with inner-city youth, mentally ill, homeless, and internationals. He helped develop an engineering college in Tigray, Ethiopia and is currently collaborating with the College’s Humanitarian Disaster Institute in projects in Japan and the Philippines.
He has a lifelong interest in playing classical and worship music on violin.
