Yamen Abbas

Hi there! My name is Yamen Abbas, and I’m a medical student at WashU interested in orthopaedic surgery. Much of my research looks at how peripheral nerves recover after injury. I also enjoy making things, from furniture to software.

I put together Bones & Nerves to share some of the tools I’ve built alongside that research. You can try the interactive projects here or read about the von Frey app I’ve been developing. Have a look around, and feel free to get in touch.
