Faculty AffiliatesEric Bubar
Associate Professor, Engineering,
Email: eric.bubar@marymount.edu

Eric has a formal degree in Applied Physics with a research concentration in Stellar Astrophysics. He uses these general research skills in developing open source solutions for individuals in need of assistive technologies by using hobbyist microcontrollers, electronics, and 3D printing/design. Through this work, Eric has collaborated with individuals worldwide (largely through eNABLE and the Alliance for Project Based Learning Solutions) to create and deploy upper limb assistive devices that provide some of the functionality offered by prosthetic limbs in situations where medically validated devices are unavailable. Through his research lab at Marymount University, he continuously works on creating solutions to problems as diverse as adapting devices to allow children with limb differences to play musical instruments to create tools to aid police officers with rehabilitation exercises. Most recently Eric has brought a virtual reality development lab to the university with his design of virtual reality STEM-themed escape rooms and work with the Marymount Center for Optimal Aging to create gamified rehabilitation/exercise experiences and simulations allowing the practice of ADLs (Activities of Daily Living).
