Johns Hopkins Engineer Develops Groundbreaking Prosthetic Limb

30 August 2017

Johns Hopkins Engineering offers online and part-time master's degrees and certificates in 20 program areas spanning the fields of engineering and applied sciences.

Bill Haris is a recent graduate of the Electrical and Computer Engineering program. During his program, he embarked on an independent study project in which he developed a new, lower-cost prosthetic limb.

Haris was inspired by and worked closely with his instructors Bob Armiger and Jeff Lesho, both of the Johns Hopkins University Applied Physics Laboratory. Armiger and Lesho have been instrumental in DARPA's Revolutionizing Prosthetics project.

This opportunity is a common one for online and part-time Johns Hopkins Engineering students because most instructors there are currently working in their fields. As a result, they are able to discuss real-world examples and bring their expertise directly into the classroom.

Using open-source technology in his project, Haris was able to incorporate advanced features like pattern recognition and machine learning into upper-extremity prostheses for a fraction of the price. He presented his groundbreaking work at a conference this year.

You can read more about Haris's project on JHU Engineering magazine’s website.

The part-time and online graduate programs at Johns Hopkins Engineering provide students with the flexibility to earn master's degrees and certificates while they continue working. Given the fact that most instructors are practicing engineers and scientists, it is truly “education for professionals by professionals.” Students can complete their coursework 100% online in many of the part-time graduate programs – from Computer Science and Electrical & Computer Engineering to Data Science and Environmental Engineering – with new online options added every term.
