Professor Westphal has been at Wabash since 2004 and teaches in the Mathematics and Computer Science Department. His primary research interest is in the development of efficient numerical methods for problems in continuum mechanics, an area that is at the intersection of mathematics, computer science, and physics. It's perhaps no surprise that his favorite courses to teach are also in the area of applied and computational mathematics. Across campus he has been involved in the pre-engineering program at Wabash, various undergraduate research activities, and a host of mathematics related student activities. In his free time, professor Westphal can be found reading, juggling, skateboarding, mountain biking, or hanging out with his wife and two kids. Check out his personal webpage for more info.
