Nasty Nine Trail Run near finish line, Sept 2022
Greeted by personal fan club (aka the kiddos) a few minutes later!

Hello, welcome to Jon E’s website! I teach a bunch of outstanding, curious, and enthusiastic W&L students. Actually, I learn a lot from them!  My lab (the “Colon Crew”) performs research at the intersection of physics, medicine, and biology. We make new biomedical tools to non-invasively study gastrointestinal motility patterns.  I serve as faculty adviser for the W&L Engineering Community Development club. We work with local and international partners developing small civil infrastructure projects (water filters, small bridges). For a quick summary of my professional life, here is my CV. For fun, I love to play outside: hiking, trail running, biking, climbing, and trying to keep up with two energetic kiddos. 

So, how did I end up becoming a professor at W&L?  I have always loved math and science, and I still love learning new things.   But my academic path was sinuous.  I switched  undergraduate majors once, and PhD tracks twice.  In retrospect, the recipe was pretty simple:  I  found topics and projects that really ignited my curiosity and passion to apply science for the public good, took a chance on them, and have worked hard chipping away at them.  Moral of the story: I don’t think anyone really needs a long-term plan.  Find what you love, and invest yourself in it and build community doing so.
