About Me
Christopher Cutler
I'm an M4 at CMS at Rosalind Franklin University in Illinois who's passionate about Neurosurgery and innovation. I invented Knotrainer to help myself learn how to suture wherever I was without carrying around a large suture training board. Before medical school, I worked as a Neurosurgical Surgical Technician and volunteered as an EMT-B on my local SAR team. When I'm not working on research projects, I love to spend time with my wife and two kids, canyoneer and mountain bike.
