About

Dr. M.H. Freeman is a pioneering biomedical engineer whose research focuses on the intersection of magnetic actuation and robotic surgery for minimally invasive otologic interventions. Their most notable contribution is the development of magnetically steered robotic systems for cochlear-implant electrode array (EA) insertion, a procedure demanding extreme precision to avoid trauma to the delicate inner ear. Freeman’s landmark 2020 study, "Magnetically Steered Robotic Insertion of Cochlear-Implant Electrode Arrays: System Integration and First-In-Cadaver Results," demonstrated that using external magnetic fields to steer magnet-tipped EAs significantly reduces insertion forces, a critical factor in preserving residual hearing. This work, which has garnered 51 citations, represents a paradigm shift from passive to active steering in cochlear implantation. By integrating robotic control with magnetic guidance, Freeman has laid the groundwork for safer, more consistent surgical outcomes, potentially expanding candidacy for hearing preservation. Their research is widely cited in the fields of surgical robotics, neuroprosthetics, and otolaryngology, establishing Freeman as a leading voice in the next generation of image-guided, minimally invasive ear surgery.
